During the manufacture of sulfuric acid, sulfur dioxide is converted to sulfur trioxide. 2SO_(2)+O_(2)arrow 2SO_(3) Which type of reaction is this? A displacement B neutralisation C oxidation D thermal decomposition

The correct answer is C. oxidation.<br /><br />In the given reaction, sulfur dioxide (SO2) is converted to sulfur trioxide (SO3) by reacting with oxygen (O2). This type of reaction is known as an oxidation reaction.<br /><br />Oxidation reactions involve the gain of oxygen or the loss of hydrogen by a substance. In this case, sulfur dioxide is oxidized to sulfur trioxide by gaining oxygen.<br /><br />Displacement reactions involve the replacement of one element with another in a compound. Neutralization reactions occur between an acid and a base to form a salt and water. Thermal decomposition reactions involve the breaking down of a compound into simpler substances by heat.<br /><br />Therefore, the correct answer is C. oxidation.
