Answer 2

To indicate the presence of a gaseous reactant or product, we use the symbol (g).

• In a chemical reaction, the gaseous reactants and products are represented by the symbol (g).
• For example, one mole of nitrogen gas reacts with three moles of hydrogen gas to form two moles of ammonia gas.
• Hence the reaction is represented is as follows-
• $N_2(g)+3H_2(g)\rightarrow 2NH_3(g)$.
• Here the nitrogen, hydrogen and ammonia gases are represented by the symbol "g".
