Question

Write the balanced chemical equations for the following reactions:
(a) Zinc + Silver nitrate → Zinc nitrate + Silver
(b) Sodium + Water → Sodium hydroxide + Hydrogen.

Hint:

Balancing chemical equations ensures that the law of conservation of mass is followed.

Answer 1

Balanced Chemical Equations:
\[ \text{(a) } Zn + 2AgNO_3 \rightarrow Zn(NO_3)_2 + 2Ag \] \[ \text{(b) } 2Na + 2H_2O \rightarrow 2NaOH + H_2 \]
