Question

1) State any 2 difference between metals and non-metals.

2) Write the equation for the following reaction :-

a) Aluminium and dilute hydrochloric acid.

b) Sulphur and concentrated nitric acid.​

Answer 1

Answer:

1. "Metals are good conductors of heat and electricity. Non-metals are bad conductors of heat and electricity. Metals are Lustrous and can be polished. Non-metals are non-lustrous and cannot be polished.
2. Aluminium reacts with dilute hydrochloric acid to give aluminum chloride and hydrogen gas. The balanced equation is = 2Al(s) + 6HCl(aq) -----> 2AlCl3(aq) + 3H2(g).
3. S+6HNO3→H2SO4+2H2O+6NO2."

Answer 2

Answer:-

1)

→ Metals are good conductors of heat and electricity.

→Metals are Lustrous and can be polished.

→ Non-metals are bad conductors of heat and electricity.

→ Non-metals are non-lustrous and cannot be polished

2)

a) 2Al(s) + 6HCl(aq) →2AlCl3(aq) + 3H2(g)

b) S + 6HNO3 → H2SO4 + 2H2O + 6NO2
