Question

b)A white compound A when strongly heated produces a yellow residue B which turns white on cooling. A colourless gas Cis also released which turns freshly prepared lime water milky.
i)Write a balanced chemical equation for the heating of the compound A.
ii)Give a balanced chemical equation when B reacts with sodium hydroxide.
iii)What will you observe when the gas Cis passed in excess through the lime water?
