Question

.State three reasons for the following facts (i) Sulphur is a non-metal (ii)Magnesium is a metal One of the reasons must be supported with a chemical equation.

Answer 1

Explanation:

1. Sulphur is a non-metal

Poor conductor of heat and electricity

Neither malleable nor ductile

Sulphur dioxide is acidic oxide.

Equation:-

S + O2 →SO2 SO2 + H2O → H2SO3 (Sulphurous acid)

2. Magnesium is a metal

Good conductor of heat and electricity

Malleable nor ductile

Magnesium oxide is basic in nature.

Equation:-

2Mg + O2 →2MgO2 MgO + H2O → Mg(OH)2 (Magnesium hydroxide).
