1. Complete the missing components/variables given as 'x' and 'y' in the following reactions.
\(Cu\)(s) + \(2AgNO_3\)(aq) → \(Cu(NO_3)_2\)(aq) + x(s)
 
\(Cu\)(s) + \(2AgNO_3\)(aq) → \(Cu(NO_3)_2\)(aq) +
 
Therefore, in the above reaction, x is (s); \(Ag\) gets replaced by \(Cu\).
 
2. Which among the following changes are exothermic or endothermic in nature?
Dilution of sulphuric acid.
  
\(H_2​SO_4\) ​+ \(2H_2​O\) → \(2H_3​O^+\) + \(SO_4{^2}{-}\) ​+
 
The process of dilution of sulfuric acid with water is because it involves the evolution of heat.
