Question

Hydrogen gas combines with nitrogen to form Ammonia. Translate the following statement into the chemical equation and then balance the equation?

Answer 1

Hydrogen gas combines with Nitrogen to form Ammonia:

• The representation of a chemical reaction in the form of a chemical formula with the help of an arrow pointing from reactant to product is called a chemical equation and where the number of atoms of all the elements is equal on both sides of the equation is known as a balanced chemical equation.
• Here, the law of conservation of mass governs the balancing of a chemical equation.
• The given chemical reaction is; Hydrogen gas combines with nitrogen to form ammonia.
• The following chemical reaction takes place when hydrogen gas reacts with nitrogen to form ammonia which can be shown as;

$\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Nitrogen}}{{\mathrm{N}}_2\left(\mathrm{g}\right)}\rightleftharpoons \underset{\mathrm{Ammonia}}{{\mathrm{NH}}_3\left(\mathrm{g}\right)}$

• By balancing the equation above, we get can get;

$\underset{\mathrm{Hydrogen}}{3{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Nitrogen}}{{\mathrm{N}}_2\left(\mathrm{g}\right)}\rightleftharpoons \underset{\mathrm{Ammonia}}{2{\mathrm{NH}}_3\left(\mathrm{g}\right)}$

Hence, the translation of the above following statement into the balanced chemical equation is given as:

$\underset{\mathrm{Hydrogen}}{3{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Nitrogen}}{{\mathrm{N}}_2\left(\mathrm{g}\right)}\rightleftharpoons \underset{\mathrm{Ammonia}}{2{\mathrm{NH}}_3\left(\mathrm{g}\right)}$
