Answer 1

Answer:

Decomposition of water

Explanations

What is a chemical reaction?

A chemical reaction s defined as the transformation of one subtsnace to another. Given the chemical reaction;

water → hydrogen + oxygen

The chemical formulas for the reactant and products are;

Water = H2O

Hydrogen = H2

Oxygen = O2

The chemical equation in terms of their chemical formula is given as;

$H_2O\rightarrow H_2+O_2$

The balanced form of the reaction is given as;

$2H_2O\rightarrow2H_2+O_2$

From the reaction, you can see that water decomposes into hydrogen oxygen, therefore the chemical reaction given describes decomposition of water
