Write "true" or "false" for each statement.

(a) we balance chemical equations as we do because energy must be conserved.
(b) if the reaction 2 o3(g) s 3 o2(g) goes to completion and all o3 is converted to o2, then the mass of o3 at the beginning of the reaction must be the same as the mass of o2 at the end of the reaction.
(c) you can balance the "water-splitting" reaction h2o(l) s h2(g) + o2(g) by writing it this way: h2o2(l) s h2(g) + o2(g).

For a: The given statement is False.

For b: The given statement is True.

For c: The given statement is False.

Explanation:

For a:

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor can be destroyed but it can only be transformed from one form to another form.

The total mass on the reactant side must be equal to the total mass on the product side.

For Example: The formation of water from hydrogen and oxygen gas follows:

Total mass on reactant side =  

Total mass on product side =  

Hence, the given statement is False.

For b:

The given chemical reaction follows:

The given equation is a balanced chemical equation and will follow law of conservation of mass.

Thus, after the completion of a chemical reaction, total mass of the reactants taken in the beginning will be equal to the total mass of the products produced at the end.

Hence, the given statement is True.

For c:

The chemical reaction for the water-splitting follows the equation:

To balance a chemical equation, coefficients in front of the chemical species changes, not the subscripts.

Coefficients are defined as the numbers that are written in front of the atoms in a chemical reaction. They represent the number of moles of substance in a chemical reaction.

Subscript numbers are defined as the number of atoms of each element present in a compound.

The balanced chemical equation follows:

Hence, the given statement is False.
