Answer 2

The Theory

Before performing the experiment, let’s find out what combination reactions are!

A combination reaction is a general category of chemical reactions. It may be defined as a chemical reaction in which two or more substances combine to form a single substance under suitable conditions.

Combination reactions are also known as synthesis, because in these reactions new substances are synthesized.

The general equation that describes a combination reaction is:

What are the types of combination reaction?

Combination reactions are of three types.

       

Similarly, non-metals may react with highly active metals to form covalent compounds. Example, sulphur reacts with oxygen gas to form gaseous sulphur dioxide
