Question

Give balanced equation:
(a) Dilute sulphuric acid reacts with Aluminium powder
(b) Potassium carbonate reacts with hydrochloric acid
(c) Potassium hydroxide reacts with nitric acid
(d) Zinc reacts with sodium hydroxide solution

Answer 1

a) Dilute sulphuric acid + Aluminium powder $\to$ Aluminium sulphate + Hydrogen gas
$H_{2}S{O}_4\left(aq\right)+2Al\left(s\right)\to A{l}_2\left(S{O}_4{)}_3\right(aq)+3H_2\uparrow$

b) $K_{2}C{O}_3+2HCl\to 2KCl+H_{2}O+C{O}_2$

c) $HN{O}_3\left(aq\right)+KOH\left(aq\right)\to KN{O}_3\left(aq\right)+H_{2}O\left(l\right)$

d) $Zn+2NaOH\to Zn(OH{)}_2+2Na$
