Question

Write the formulae and then balance the following chemical equations.

Magnesium + Silver nitrate $\to$ Magnesium nitrate + Silver

Answer 1

• Formulae: $\mathrm{Magnesium}-\mathrm{Mg},\mathrm{Silver}\mathrm{nitrate}-{\mathrm{AgNO}}_3,\mathrm{Magnesium}\mathrm{nitrate}-\mathrm{Mg}{\left({\mathrm{NO}}_3\right)}_2,\mathrm{Silver}-\mathrm{Ag}$
• When magnesium reacts with silver nitrate it gives magnesium nitrate and silver in solid form.

$\underset{\mathrm{Magnesium}}{\mathrm{Mg}\left(\mathrm{s}\right)}+\underset{\mathrm{Silver}\mathrm{nitrate}}{{\mathrm{AgNO}}_3\left(\mathrm{aq}\right)}\to \underset{\mathrm{Magnesium}\mathrm{nitrate}}{\mathrm{Mg}{\left({\mathrm{NO}}_3\right)}_2\left(\mathrm{aq}\right)}+\underset{\mathrm{Silver}}{\mathrm{Ag}\left(\mathrm{s}\right)}$

Balanced chemical equation is as follows:

$\underset{\mathrm{Magnesium}}{\mathrm{Mg}\left(\mathrm{s}\right)}+\underset{\mathrm{Silver}\mathrm{nitrate}}{2{\mathrm{AgNO}}_3\left(\mathrm{aq}\right)}\to \underset{\mathrm{Magnesium}\mathrm{nitrate}}{\mathrm{Mg}{\left({\mathrm{NO}}_3\right)}_2\left(\mathrm{aq}\right)}+\underset{\mathrm{Silver}}{2\mathrm{Ag}\left(\mathrm{s}\right)}$
