13. Exercises VI

Exercise condition:

2 m.

1. Balance the following chemical equation.

$HNO_3$ +

$Ca(OH)_2$ →

$Ca(NO_3)_2$ +

$H_2O$

$2HNO_3$ + $Ca(OH)_2$ → $Ca(NO_3)_2$ + $2H_2O$
$2HNO_3$ + $2Ca(OH)_2$ → $Ca(NO_3)_2$ + $2H_2O$
$HNO_3$ + $Ca(OH)_2$ → $Ca(NO_3)_2$ + $2H_2O$
$2HNO_3$ + $Ca(OH)_2$ → $Ca(NO_3)_2$ + $2H_3O$
$2HNO_3$ + $Ca(OH)_2$ → $Ca(NO_3)_2$ + $3H_2O$

2. Write the balanced chemical equations for the following reactions.

Calcium hydroxide + Carbon dioxide → Calcium carbonate + Water

$Ca(OH)_2$ + $CO_3$ → $CaCO_3$ + $H_2O$
$Ca(OH)_2$ + $CO_2$ → $CuCO_3$ + $H_2O$
$Cu(OH)_2$ + $CO_2$ → $CaCO_3$ + $H_2O$
$Ca(OH)_2$ + $CO_2$ → $CaCO_3$ + $H_2O$
$Ca(OH)_2$ + $CO_2$ → $CaCO_3$ + $5H_2O$
