Question

2. Write the formula and then balance the following equations.
a. Chlorine + Sodium hydroxide → Sodium chloride + Sodium chlorate +
water
b. Iron sulphate + Hydrochloric acid + Iron chloride + Hydrogen sulphide
C. Calcium + Water + Calcium hydroxide + Hydrogen
d. Zinc carbonate + Zinc oxide + Carbon dioxide​

Answer 1

Answer:

The Balanced equations are as follows :

a.) Chlorine + Sodium hydroxide → Sodium chloride + Sodium chlorate +

water.

Hence the equation is :

3Cl₂ + 6NaOH ---> NaClO₃ + 5NaCl + 3H₂O

b.) Iron sulphate + Hydrochloric acid → Iron chloride + Hydrogen sulphide

Hence the equation is :

2FeCl₃ + 2H₂S ---> FeS₂ + FeCl₂ + 4HCl

c.) Calcium + Water → Calcium hydroxide + Hydrogen

Hence the equation is :

Ca + 2H₂O ---> Ca (OH)₂ + H₂

d.) Zinc carbonate ---> Zinc oxide + Carbon dioxide​

Hence the equation is :

ZnCO₃ → ZnO + CO₂
