Step 1: Address question 4(a). In Chamber I, zinc oxide (ZnO), which is a basic oxide, reacts with sulphuric (VI) acid (H_2SO_4). This is an acid-base reaction. The type of reaction taking place in Chamber I is a neutralization reaction. Step 2: Address question 4(b). From the context of 4(a), Chamber I involves ZnO(s) + H_2SO_4(aq) ZnSO_4(aq) + H_2O(l). Substance A is therefore zinc sulphate ($ZnSO_
