Answer 1

Answer:

Detail is given below.

Explanation:

Chemical equation:

4NH₃ + 3O₂      →     2N₂ + 6H₂O

This reaction shows that when ammonia react with oxygen it form water and nitrogen gas.

There are two reactants on left hand side oxygen and ammonia. Ammonia is formed when nitrogen and hydrogen react. While on right hand side there are two products nitrogen and water. Water is formed by the reaction of hydrogen and oxygen.

The given reaction also shows that it follow the law of conservation of mass.

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.  

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

Luciana explains to Eric how electricity flows in a circuit. Which sentences are a part of her explanation? Select all that apply.



A. Without a resistor, electricity cannot flow in a circuit.


B. Without a switch, electricity cannot flow in a circuit.


C. For electricity to flow in a circuit, the circuit must be complete.


D. An insulator such as plastic is needed for electricity to flow in a circuit.


E. A conductor is needed for electricity to flow in a circuit.

Answers

I’m pretty sure it c hope that helped

Answer:

E. A conductor is needed for electricity to flow in a circuit.

Explanation:

Electric current can flow without a resistor, as in short circuit.

A short circuit is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance.

Without a switch, electricity can flow in a circuit, switch is only used to close or open the circuit.

Thus, the only correct option is  E

E. A conductor is needed for electricity to flow in a circuit.

Why do acids and bases neutralize eachother?

Answers

Answer:

Explanation:

When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.

a sample of alcohol has a density 0.82 g/ml.what is the mass of 5500 mL of the alcohol

Answers

Answer:

The answer is 4510 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

density = 0.82 g/mL

volume = 5500 mL

We have

mass = 0.82 × 5500

We have the final answer as

4510 g

What colors are the fireworks in the photo? How do you
think the matter and energy of fireworks of different colors are similar and
different?

Answers

Answer:

Shortly after, the electron will fall back down to a lower energy level, releasing energy in the form of light. Therein lies the key to colorful fireworks!

The matter and energy of fireworks simply rely on the flow of electrons from the ground stage to the excitatory stage.

What is Matter?

Matter may be defined as any sort of substance that is constructed of numerous types of particles that occupy physical space and possess inertia. In simple words, matter may be characterized as anything which occupies space and has mass.

When the electrons move from the ground stage to the excitatory stage, they require a significant amount of energy in any form. But when they fall back to the ground stage from the excitatory stage, they liberates energy.

The same principle is applied in the colorful observation of fireworks. The stored energy is released and different colors of fireworks become visible.

Therefore, the matter and energy of fireworks simply rely on the flow of electrons from the ground stage to the excitatory stage and vice-versa.

Answers

Answer:

Potential energy is the stored energy in an object or thing, while kinetic energy is the energy which an object contains because of a particular motion.

Explanation:

Potential energy is energy that is stored for example a wind up toy, it has energy but in order for you to get kinetic energy, it has to move. So kinetic energy is moving energy.

The difference is that potential is stored and kinetic is moving energy.

explain how to balance the chemical equation, KClO3 ⟶ KCl + O2 and include all steps

Answers

The balance of chemical equation : 2KClO₃ ⟶ 2KCl + 3O₂

Further explanation  

Equalization (balance) of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

Reaction

[tex]\tt KClO_3\Rightarrow KCl+O_2[/tex]

1. Coefficient

KClO₃ ⟶ aKCl + bO₂

2. Equation

K ⇒ left =1, right=a ⇒a=1

Cl⇒ left =1, right=a ⇒a=1

O ⇒ left = 3, right = 2b ⇒3=2b, b = 1.5

The equation turns into :

KClO₃ ⟶ KCl + 1.5O₂

multiplied by 2

2KClO₃ ⟶ 2KCl + 3O₂

Contains elements carbon, hydrogen and oxygen, the empirical formula of butanedion is C2H3O and its molar mass is 86.09% find its empirical formula

Answers

Answer:

Molecular formula = C₄H₆O₂

Explanation:

Given data:

Empirical formula of butanedion = C₂H₃O

Molar mass of  butanedion = 86.09 g/mol

Molecular formula  butanedion = ?

Solution:

Formula:

Molecular formula = n(empirical formula)

n = molar mass of compound / empirical formula mass

empirical formula mass  = 2×12 +1.008×3 +1×16 = 43.024

n = 86.09 / 43.024

n = 2

Molecular formula = n (empirical formula)

Molecular formula = 2 (C₂H₃O)

Molecular formula = C₄H₆O₂
