Complete the following sentence. A thermal decomposition reaction is __ a type of reaction where a more reactive metal from the reactivity series is able to take the place of a less reactive metal in a compound. a type of reaction where a substance called fuel reacts with oxygen It is also called burning. a type of reaction where a single compound is broken down to form simpler compounds and elements by heat. a type of reaction where a substances gains or combines with oxygen.

Answer 1

The correct description for thermal decomposition reaction is: "A type of reaction where a single compound is broken down to form simpler compounds and elements by heat."

Answer 2

## Step 1:In doing this question, first we need to understand what a thermal decomposition reaction is. In chemistry, thermal decomposition is a type of reaction where a single substance (usually a compound) breaks down into two or more distinct products due to the application of heat. Given that context, we can then look at the options at hand to figure out which appropriately describes a thermal decomposition.
