Question

a chemical equations shows the ____ on the right side of the yield arrow. a products b reactants
in the example equation that illustrates the synthesis of water, each element has a 2 subscript because they are ____. a gases b diatomic
to balance a chemical equation, we use ____. a coefficients b subscripts

Explanation:

1. In a chemical equation, products are on the right - hand side of the yield arrow. Reactants are on the left - hand side.
2. In the synthesis of water ($2H_2 + O_2

ightarrow2H_2O$), hydrogen and oxygen are diatomic elements, which is why they have a subscript of 2.

1. To balance a chemical equation, we adjust the coefficients in front of the chemical formulas, not the subscripts which are part of the chemical identity of the substances.

Answer:

1. A. products
2. B. diatomic
3. A. coefficients
