Question

Complete and balance the following chemical equations
(a) NaCl (aq) + H2O (l) Electricity→
(b) NaHCO3 Heat→ (c) NaCl + NH3 + H2O + CO2 →
(d) Ca(OH)2 + Cl2 →

Answer 1

Explanation:

       $NaCl (aq) + H_2 O (l) Electricity→ NaoH + HCL$

• When $Nacl$ (aqueous state) reacts with Water in the presence of electricity it will form $NaOH$ and $HCL$ as the sub resultant product.

        $\mathrm{NaHCO}_{3} \text { Heat } \rightarrow \mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O}$

• When $NaHCO_3$ is heated it will get form$H_2 O$ and $CO_2$

        $NaCl + NH3 + H2O + CO2 → NaHCO_3 + NH_4CL$

• When $Nacl$ and $NH_3$ in the presence of $H_2 O$ and $CO_2$ ,It will result in $NaHCO_3$ and $NH_4CL$

        $Ca(OH)2 + Cl2 = Ca(ClO)2 + CaCl_2+ H_2 O$

• When $Ca(OH)^2$ reacts with $Cl_2$, It forms $CaCl_2$and $H_2 O$.
