It's how many atoms are in two water molecules (H2O)?
Answer:
The chemical formula for water is H2O which means that every molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O). Here comes the key part. From the Periodic Table of Elements, one sees that one mole of hydrogen atoms weighs 1 gram while one mole of oxygen atoms weighs 16 grams.
Explanation:
:)
The number of atoms present in two water molecules is 6 atoms. 4 hydrogen atoms and 2 oxygen atoms.
What are atoms?Atoms are the basic unit of a substance. An atom is made of a nucleus, protons, neutrons and electrons. Different atoms combines to form a molecule and molecules combines to form compounds.
Water has the formulas H₂O, thus one molecule of water contains 2 hydrogen and one oxygen. Therefore, two molecules of water that is (H₂O)₂ have 4 hydrogen and 2 oxygens thus, a total of 6 atoms.
Hence, the number of atoms present in two molecules of water is 6.

3.Zinc has an atomic number of 30 and a mass number of 65, how many neutrons does it have?
30
65
35
95
Answer:
35
Explanation:
Given parameters:
Atomic number of zinc = 30
Mass number of zinc = 65
Unknown
Number of neutrons = ?
Solution:
The mass number of an atom is the sum of its protons and neutrons;
Mass number = Protons + neutrons
Atomic number is the number of protons in an atom;
Atomic number = Protons
So;
Mass number = Atomic number + Neutrons
Neutrons = Mass number - Atomic number
Neutrons = 65 - 30 = 35
The number of neutrons in the atom is 35

A hiker tries to prepare a hard-boiled egg on the high slopes of Mount Everest. The base camp is located 5,300 meters above sea level. The hiker observes that the water begins to boil at 82⁰C, much lower than the 100⁰C needed to cook the raw egg. He hopes that just leaving the egg in the boiling water longer will let the egg cook. Will he have hard-boiled eggs for breakfast?
Answer:
He will not have hard-boiled eggs for breakfast
Explanation:
The given parameters are;
The elevation at which the base camp of the hiker is located = 5,300 meters
The boiling point of water at the elevation of the base camp = 82°C
The temperature required to cook the raw egg = 100°C
Therefore, we have;
The temperature of the boiling water at the given elevation of the base camp 82°C < The temperature required to cook the raw egg 100°C
Therefore, the eggs will not be hard boiled.
The hiker won't have hard-boiled eggs for breakfast as a result of the
boiling point of water being less than 100⁰C.
The boiling point decreases with an increase in altitude. The hiker was at
5,300 meters above sea level which made the boiling point of water to be
decreased to 82⁰C.
Since the water isn't able to achieve the boiling point of 100⁰C, then the raw
egg won't be hard boiled for breakfast.

A student found the mass of a brick: 50 grams. The volume was 10 cubic centimeters. If the student had 5 bricks, what would be the total density?
Answer:
The answer is 5 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
The mass of one brick is 50 g
the volume of one brick is 10 cm³
Since the student had 5 bricks
Total mass = 5 × 50 = 250 g
total volume = 5 × 10 = 50 cm³
So the total density is
[tex]density = \frac{250}{50} = \frac{25}{5} \\ [/tex]
We have the final answer as
5 g/cm³Hope this helps you

Why do some transition metals have multiple oxidation states?
Transition metals have multiple oxidation states because of their (a. completely filled b. partially filled c. empty) (s, p, d, or f) sublevel.
Answer:
because of energy difference between (n1)d and ns orbitals (sub levels) and involvement of both orbital in bond formation
Explaination:
the reason is that there is a difference in energy of orbitals of an atom of transition metal, so there (n1)d orbitals and there ns orbitals both make a bond and for this purpose they lose an electron that is why both sublevels shows different oxidation state.
Hope this helped you
Transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.
What are transition metals?Transition metals are defined as essentially, a configuration attended by reactants during complex formation, as well as the reaction coordinates.
It can also be defined as a very short-lived atomic configuration at a reaction-energy diagram's local energy maximum.
Transition metals are best defined as an element with a partially filled d sub-shell on its atom or that can give rise to cations with an incomplete d sub-shell.
Transition state is defined as a chemical reaction is defined as a certain configuration along the reaction coordinate.
Oxidation state is defined as the total number of electrons that have been deleted or added to an element.
It can also be defined as an atom's charge if all of its links to other atoms were entirely ionic.
Thus, transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.
