Question

symbol chemical equation examples

Answer 1

Hydrogen and oxygen are indicated by (g), which means they are gases. Water is marked (l), which means it is a liquid. Another symbol you may see is (aq), which means the chemical species is in water—or an aqueous solution.

Answer 2

For Example . This is a reaction between methane (CH4) and oxygen (O2), producing carbon dioxide (CO2) and water (H2O). The reaction shown is a combustion reaction: a compound reacts with oxygen and produces carbon dioxide and water.

(CH4 + O2 =CO2 + H2O)
