Question

A decomposition occurs when you open a can or bottle of soda. Carbonic acid, H2CO3, is in carbonated beverages. It decomposes into carbon dioxide and water. If you leave an open soda can out for a long time, it loses its fizz. Which equation represents the balanced chemical equation for this reaction?

Answer 1

An example of a balanced chemical equation representing a reaction is:

2H2 + O2 → 2H2O

It represents two molecules of hydrogen reacting wit one molecule of oxygen to form two molecules of water.

Answer 2

An example of a balanced chemical equation representing a reaction is:

2H2 + O2 → 2H2O

It represents two molecules of hydrogen reacting wit one molecule of oxygen to form two molecules of water.
