1. Silver metal can displace hydrogen gas from nitric acid.

Silver metal has the ability to displace hydrogen gas from nitric acid.
Silver cannot displace \(H_2\) from \(HNO_3\) acid since it is located below hydrogen in the activity series.

2. The pH of rain water containing dissolved gases like \(SO_3\), \(CO_2\), \(NO_2\) will be less than \(7\).

The pH of rain water containing dissolved gases like \(SO_3\), \(CO_2\), \(NO_2\) will be less than \(7\).
