Answer 3

Reactants for the Reaction with Calcium Chloride:

The substances that react with calcium chloride are:

а) HNO3 (nitric acid) б) KCl (potassium chloride) в) Ca(OH)2 (calcium hydroxide) г) Na2CO3 (sodium carbonate)

Balanced Chemical Equation for the Reaction:

The balanced chemical equation for the reaction of calcium chloride with the given substances are as follows:

а) With HNO3 (nitric acid): ``` CaCl2 + 2HNO3 → Ca(NO3)2 + 2HCl ```

б) With KCl (potassium chloride): ``` CaCl2 + 2KCl → CaCl2 + 2KCl ```

в) With Ca(OH)2 (calcium hydroxide): ``` CaCl2 + 2Ca(OH)2 → 2CaCl2 + 2H2O ```

г) With Na2CO3 (sodium carbonate): ``` CaCl2 + Na2CO3 → CaCO3 + 2NaCl ```

These balanced chemical equations represent the reactions of calcium chloride with the specified substances.
