Which pair of products are formed when amorphous boron is burned in air?

Iron burns in air to from

An amorphous soild A burns in air to form a gas B which turns lime water milky. The gas is also produced as a by - product during roasting of sulohide ore. This gas decolourises acidified aqueous KMnO_(4) solution and reduces Fe^(3+) to Fe^(2+) . Identify the solid A and the gas B and write the reactions involved.

An amorphous solid (X) burns in air to form a gas ( Y) which turns lime water milky. This gas decolourises aqueous solution of acidified KMnO_(4). Gas (Y) reacts with oxygen to give another gas (Z) which is responsible for acid rain. X, Y and Z are
