(a) Generally, non-metals react with acids.
(b) Sodium is a very reactive metal.
(c) Copper displaces zinc from zinc sulphate solution.
(d) Coal can be drawn into wires.

Answer 1

a) Generally, non-metals react with acid $\to False$

b) Sodium is a very reactive metal $\to True$

c) Copper displace zinc from zinc sulphate solution $\to False$

d) Coal can be drawn into wire $\to False$.

Note:

(a) Metals react with acid because metals are Eierro positive, $\therefore$ metals can give $e^{\ominus }$ to hydrogen gas while non-metals not

(c) Zinc is more reactive metal and Hence it displaces copper from copper sulphate solution.

(d) Coal is a non-metals and that is why it is not ductile in nature.
