Answer: C) 8 moles
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
According to stoichiometry of the given balanced equation:
2 moles of decomposes to form 2 moles of
Thus 8 moles of decomposes to form= of
Thus 8 moles of are produced from 8 moles of
Answer:
The Surface Of The Earth
Explanation:
The Troposphere contains about half of all the air in the entire atmosphere. Because it is at the bottom, air pressure, or the weight of the air, is greatest in this layer. (The surface of the earth is in this layer, making it the answer.)
Answer:
B. It is a nonliving resource.
Explanation:
The definition of abiotic is "nonliving," and examples of abiotic resources may include soil or water.
<u>Answer:</u> The mass of the reactants is always equal to the mass of the products.
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be formed nor be destroyed but it can only be transformed from one form to another. This law is followed by all the balanced chemical reactions.
This law simply means that the total mass on the reactant side is always equal to the total mass on the product side.
For example: Formation of water from hydrogen and oxygen gas.
Total mass on the reactant side =
Total mass on the product side =
As, the total mass on the reactant side is equal to the total mass on the product side. Hence, this equation follows law of conservation of mass.
