(ii) Barium chloride + Aluminium sulphate
-Barium sulphate + Aluminium chloride
(iii) Sodium + Water-
Sodium hydroxide + Hydrogen



plz give me answers​

Answer 1

$\sf\: \fcolorbox{pink}{pink}{Balanced \: chemical \: equations \: :}$

1) Hydrogen + Chlorine $\longrightarrow$ Hydrogen chloride.

$\implies$ H2 + Cl2 $\longrightarrow$ 2HCL.

2) Barium chloride + Aluminium sulphate $\longrightarrow$ Barium sulphate + Aluminium chloride.

$\implies$ Bacl$_2$ + Al2(SO4)3 $\longrightarrow$ BaSo4 + AlCl3.

3) Sodium + water $\longrightarrow$ Sodium hydroxide + Hydrogen.

$\implies$ 2Na + 2H2O $\longrightarrow$ 2NaOH + H2.

• Chemical reaction :- The reaction in which one or more substances are transformed to one or more new substances are called chemical reaction.
• $\red{\sf Example \: :}$ $\sf H_2 \: + \: O_2 \: \longrightarrow 2H_2 O$
