Why does granite have larger crystals than obsidian?

Answers

Answer 1

Answer:Granite forms as magma cools far under the earth's surface. Because it hardens deep underground it cools very slowly. This allows crystals of the four minerals to grow large enough to be easily seen by the naked eye. Look at the photo of granite above, notice the different crystals in the rock

Answers

The chemical formula of the gas is Option c, Helium.

We need to take into account the molar masses and the root mean square (RMS) speeds of various gases in order to ascertain the chemical formula of the gas that escapes through the pinhole 2.65 times quicker than N₂ gas.

The following equation describes how a gas's molar mass and RMS speed are related:

RMS velocity = 1/√(molar mass)

The following ratio may be established since the provided gas leaves 2.65 times more quickly than N₂ gas:

RMS speed of the given gas / RMS speed of N₂ gas = 2.65

Now, let's compare the molar masses of the options provided:

a. Ne (Neon) has a molar mass of approximately 20 g/mol.

b. O₂ (Oxygen) has a molar mass of approximately 32 g/mol.

c. He (Helium) has a molar mass of approximately 4 g/mol.

d. Ar (Argon) has a molar mass of approximately 40 g/mol.

Since the ratio of RMS speeds is greater than 1, the molar mass of the given gas must be less than that of N₂ gas. Among the options, the only gas with a molar mass significantly lower than N₂ gas is Helium (He) with a molar mass of approximately 4 g/mol.

Therefore, the chemical formula of the gas is Option C, Helium.

b) Photons of the lowest energy are emitted in a trastion from the level with n=___ to a level with n=___.
c) The emission line having the shortest wavelength corresponds to a transition from the level with n=___ to the level with n=____

Answers

a) To determine the number of possible emission lines, we need to consider the transitions between the energy levels. The formula to calculate the number of possible transitions is given by:

Number of transitions = n*(n-1)/2

where n is the number of energy levels. In this case, considering the four energy levels (n = 1, 2, 3, 4), we have:

Number of transitions = 4*(4-1)/2 = 6

Therefore, there are six possible emission lines considering only the four quantum levels.

b) The lowest energy transition occurs from the level with n=4 to the level with n=1. This transition represents the largest energy drop and therefore emits photons of the lowest energy.

c) The emission line with the shortest wavelength corresponds to the transition with the highest energy. In this case, it occurs from the level with n=4 to the level with n=1. The transition from a higher energy level to a lower energy level results in the emission of a photon with a shorter wavelength.

write the equilibrium constant expression for the following chemical equation. co(g) 2h2(g) ⇌ ch3oh(g)

Answers

The equilibrium constant expression for the reaction CO(g) + 2H₂(g) ⇌ CH₃OH(g) is K = [CH₃OH] / [CO][H₂]^{2}.

The equilibrium constant is a measure of the relative concentrations of the reactants and products at equilibrium. A large value of K indicates that the reaction is product-favored, while a small value of K indicates that the reaction is reactant-favored.

The equilibrium constant is calculated by taking the product of the equilibrium concentrations of the products and dividing it by the product of the equilibrium concentrations of the reactants.

The equilibrium concentrations are the concentrations of the reactants and products at equilibrium, which is the point at which the forward and reverse reactions are occurring at the same rate.

The equilibrium constant is a useful tool for predicting the direction of a chemical reaction. A large value of K indicates that the reaction is product-favored, meaning that the products will be more abundant at equilibrium than the reactants.

A small value of K indicates that the reaction is reactant-favored, meaning that the reactants will be more abundant at equilibrium than the products.

The equilibrium constant is also a useful tool for predicting the effect of changes in temperature and pressure on a chemical reaction. An increase in temperature will generally shift the equilibrium to the side of the reaction that produces more moles of gas.

A decrease in pressure will generally shift the equilibrium to the side of the reaction that has fewer moles of gas. The equilibrium constant is a valuable tool for understanding and predicting the behavior of chemical reactions.

explain why your dilute solution of naoh needs to be standardized

Answers

A dilute solution of NaOH needs to be standardized in order to accurately determine its concentration. Standardization involves comparing the concentration of the NaOH solution to a known concentration of a primary standard substance.

There are several reasons why standardization is necessary. Firstly, NaOH is highly hygroscopic, meaning it readily absorbs moisture from the air. This moisture absorption can alter the concentration of the solution over time, leading to inaccurate results. By standardizing the NaOH solution, we can ensure that its concentration is accurately determined at a specific point in time. Secondly, during the manufacturing and storage process, impurities may be introduced into the NaOH solution, affecting its concentration. Standardization allows us to account for these impurities and determine the true concentration of the solution. Lastly, dilution of the NaOH solution introduces a potential for errors in the preparation process, such as inaccuracies in volumetric measurements. Standardization helps correct for these errors and provides a reliable concentration value for subsequent use in various analytical procedures.

given your answer in 2, would you expect the rate of the acid catalyzed dehydration of 1-methylcyclohexanol, to be slower, faster, or about the same as for cyclohexanol? explain your answer.

Answers

The rate of the acid-catalyzed dehydration of 1-methylcyclohexanol would be faster compared to that of cyclohexanol. This can be attributed to the presence of the methyl group ([tex]CH_{3}[/tex]) in 1-methylcyclohexanol.

The methyl group is an electron-donating group that increases the electron density on the adjacent carbon atom.

As a result, the carbon-hydrogen bond adjacent to the hydroxyl group becomes weaker and more susceptible to acid-catalyzed dehydration.

Therefore, the presence of the methyl group enhances the reactivity of 1-methylcyclohexanol compared to cyclohexanol, leading to a faster rate of dehydration.

The electron-donating nature of the methyl group promotes the departure of the hydroxyl group and facilitates the formation of the double bond.

Respiration in plants: The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. ... As with photosynthesis, plants get oxygen from the air through the stomata.

Transpiration in plants: The water eventually is released to the atmosphere as vapour via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapour by leaves is known as transpiration.

Answers

The statement "You can visualize a single nucleotide change through gel electrophoresis" is false.

Gel electrophoresis is a method for separating DNA fragments by size, not for visualizing single nucleotide changes. To visualize single nucleotide changes, other methods like DNA sequencing are used.Gel electrophoresis is a method of separating molecules according to their size and electrical charge. DNA fragments are loaded onto a gel, and an electric field is applied to move the fragments through the gel matrix. The smaller fragments will travel faster and end up at the bottom of the gel while the larger ones will remain closer to the top. The gel can then be stained with a dye such as ethidium bromide to visualize the bands.However, gel electrophoresis cannot visualize single nucleotide changes. To do this, other methods like DNA sequencing or hybridization probes are used. DNA sequencing directly reads the DNA sequence and can identify individual nucleotide changes. Hybridization probes are small pieces of DNA that are designed to bind to a specific sequence of nucleotides and can be labeled with a fluorescent marker to visualize the presence or absence of a specific sequence or mutation.

Answers

To calculate the average rate of disappearance of H2O2(aq) in M/s in the first 45.0 seconds of the reaction, we need to determine the change in the concentration of H2O2 over the given time interval. By using the data provided for the volume of O2 collected at different time points, we can convert the volume of O2 to moles and then to moles of H2O2. Dividing the change in moles of H2O2 by the time interval gives us the average rate of disappearance. The correct answer from the options provided is B) 1.64 x 10^4 M/s.

To calculate the average rate of disappearance of H2O2 in M/s, we first need to convert the volume of O2 collected to moles. Since 2 mL of O2 is collected when 1 mole of H2O2 reacts, we can convert the volume of O2 to moles of H2O2 at each time point.

At 45.0 seconds, 2 mL of O2 is collected, which corresponds to 1 mole of H2O2. Therefore, the concentration of H2O2 at t = 45.0 seconds is 1 M.

At 90.0 seconds, 4 mL of O2 is collected, indicating that 2 moles of H2O2 have reacted. Hence, the concentration of H2O2 at t = 90.0 seconds is 2 M.

To calculate the average rate of disappearance, we find the change in concentration of H2O2 over the given time interval:

Change in concentration = (Final concentration - Initial concentration)

= (2 M - 1 M) = 1 M

Since the time interval is 45.0 seconds, we can calculate the average rate of disappearance by dividing the change in concentration by the time interval:

Average rate = Change in concentration / Time interval

= 1 M / 45.0 s = 1.64 x 10^4 M/s

Therefore, the average rate of disappearance of H2O2 in the first 45.0 seconds of the reaction is 1.64 x 10^4 M/s, which corresponds to option B.

Abraham, Inc., a New Jersey corporation, operates 57 bakeries throughout the northeastern section of the United States. In the past, its founder, James Abraham, owned all the companys outstanding common stock. However, during the early part of this year, the corporation suffered a severe cash flow problem brought on by rapid expansion. To avoid bankruptcy, Abraham sought additional investment capital from a friend, Dennis Bostitch, who owns Highland Laboratories. Subsequently, Highland paid $700,000 cash to Abraham, Inc., to acquire enough newly issued shares of common stock for a one-third ownership interest. At the end of this year, the accountants for Highland Laboratories are discussing the proper method of reporting this investment. One argues for maintaining the asset at its original cost: "This purchase is no more than a loan to bail out the bakeries. Mr. Abraham will continue to run the organization with little or no attention paid to us. After all, what does anyone in our company know about baking bread? I would be surprised if Abraham does not reacquire these shares as soon as the bakery business is profitable again." One of the other accountants disagrees, stating that the equity method is appropriate. "I realize that our company is not capable of running a bakery. However, the official rules state that we must have only the ability to exert significant influence. With one-third of the common stock in our possession, we certainly have that ability. Whether we use it or not, this ability means that we are required to apply the equity method."Question How should Highland Laboratories account for its investment in Abraham, Inc.? he second quartile for the numbers: 231,423,521.139347,400,345 is A 231 B. 347 C330 D. 423 47.

Each higher key (black or white) has a frequency of fo *r", where n is the distance (number of keys) from that key, and ris 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f} {:.2f} {:.2f} {:.2f} {:.2f}'.format(your_valuel, your_value2, your_value3, your_value4, your_value5)) Ex: If the input is: 440 (which is the A key near the middle of a piano keyboard), the output is: 440.00 466.16 493.88 523.25 554.37 Note: Use one statement to computers 2(1/12) using the pow function (remember to import the math module).

They have contracted you to develop the program. You are required to ANALYSE, DESIGN and IMPLEMENT a script solution that solves this problem using the following methods: A function numStudents that continuously requests the user for the number of students registered for WRSC111 until a positive value is entered. This positive number is returned by the function A function generate Marks that generates a list of n random marks in the range 0 100, where n is the input argument. Each mark is rounded to the nearest integer. The list of marks is returned by the function A function check that takes a list of marks and returns true if any mark is duplicated in the list, otherwise returns false The main script file that uses the functions written above to generate and check 25000 lists of marks for a WRSC111 class, the number of students obtained from the user. The program must determine and display the probability of any 2 students in the WRSC111 class having exactly the same mark
