Q. A student dips a zinc plate in copper sulphate solution. Write the equation of the chemical reaction taking place. Which metal is displaced during this reaction?

Q.

Explain the following

1. Reactivity of Aluminum$\left(\mathrm{Al}\right)$ decreases, if it is dipped in Nitric acid$\left({\mathrm{HNO}}_3\right)$
2. Carbon$\left(\mathrm{C}\right)$ cannot reduce the oxides of Sodium $\left(\mathrm{Na}\right)$or Magnesium$\left(\mathrm{Mg}\right)$
3. Sodium chloride$\left(\mathrm{NaCl}\right)$ is not a good conductor of electricity in solid state whereas it does conduct electricity in Aqueous state as well as in molten state
4. Iron$\left(\mathrm{Fe}\right)$ articles are galvanized
5. Metals like Sodium$\left(\mathrm{Na}\right)$, Potassium$\left(\mathrm{K}\right)$, Calcium$\left(\mathrm{Ca}\right)$, Magnesium$\left(\mathrm{Mg}\right)$ are never found in their free state in nature.
