Question

State the type of reactions each of the following represent and balance the ones that are not balanced.
(l)PbO + 2HNO${}_3$ $\to$ Pb(NO${}_3$)${}_2$ + H${}_2$O

Answer 1

PbO + 2HNO${}_3$ $\to$ Pb(NO${}_3$)${}_2$ + H${}_2$O
The given reaction is a
neutralization reaction. Lead oxide (metal oxide) is basic in nature.
therefore,it will be react with an acid like nitric acid to give lead nitrate (salt) and water,
A balanced equation should contain equal number of atoms on both the sides of the equation,
As the givn equation contains equal number of atoms on both the sides of the equation, it is balanced.
