gas formation

Explanation:

frothy bubbles produced by carbon dioxide gas are a sign that a chemical reaction has occurred when a based is mix with acid.

Explanation:

A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.Yes, the equation is balanced. ... There are the same number of Hydrogen (H) and Oxygen (O) atoms on both sides of the equation.When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide.

have a nice day
