Book Free Demo1. Why is respiration considered an exothermic reaction? Explain.
Respiration is an exothermic process because reacts with oxygen in our body's cells to produce and water, as well as energy.
\(C_6H_1{_2}O_6\)(aq) + \(6O_2\)(aq) → \(6CO_2\)(g) + \(6H_2O\)(l) + Energy.
2. In the refining of silver, the recovery of silver from silver nitrate solution involved displacement by copper metal. Write down the reaction involved.
The recovery of silver from silver nitrate solution involved displacement by copper metal. copper (\(Cu\)), being a more reactive than silver (\(Ag\)), displaces silver from silver nitrate. In this way, we can obtain from its solution.
\(2AgNO_3\)(aq) + \(Cu\)(s) → \(CuNO_3{_2}\) + \(2Ag\)(s)
