Question

Give a balanced equation for a direct combination reaction
involving:
a) Two elements – one of which is a neutral gas and the other
a yellow non-metal
b) Two elements – one of which is a neutral gas and the other
a monovalent metal
c) Two compounds – resulting in formation of a weak acid

Dear Student

a ) Neutral gas ----> O2
Yellow non-metal -----> S

Balanced equation -
3S + 4O2 ----> SO2 + 2SO3

b ) Neutral gas ----> O2
Monovalent metal ----> Na (with valency equal to 1)

Balanced equation is -
6Na + 2O2 ----->
2Naâ€‹2O +
Na2O2

c ) CO2 and H2O reacts to form Carbonic Acid,
H2CO3 (a weak acid)

Balanced equation -
CO2 + H2O ------>
H2CO3
