(a) What are A and B?
(b) Identify C and D.
(c) What will be the action of C on litmus solution? Why?
(d) State whether element B is a solid, liquid or gas at room temperature.
(e) Write formula of the compound formed when element B reacts with an element E having atomic number 5.

(a) A is sodium and B is chlorine.
(b) C is sodium chloride and D is sodium hydroxide.
(c) C will have no effect on litmus solution since it is neutral in nature.
(d) B is a gas at room temperature.
(e) EB3
