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.

AI Generated Solution

To solve the problem step by step, let's identify the components mentioned in the question and write down the relevant reactions. ### Step 1: Identify the Amorphous Solid A The question states that an amorphous solid A burns in air to produce a gas B. The gas B is also produced as a by-product during the roasting of sulfide ore. - **Amorphous Solid A**: The only solid that fits this description is **Sulfur (S)**. When sulfur burns in air, it forms sulfur dioxide (SO2). ### Step 2: Identify the Gas B ...
