Understanding the different types of chemical reactions is really interesting!

These reactions depend on how atoms interact with each other. Here are some main types you might learn about in Year 10:

1. Synthesis Reactions: This is when two or more reactants come together to make one product.

   It’s like teamwork where atoms join forces!

   For example, if we have A and B, they combine to form AB:

   ( A + B \rightarrow AB ).

2. Decomposition Reactions: This is the opposite of synthesis.

   Here, a compound breaks down into simpler parts.

   Think of it like a breakup:

   ( AB \rightarrow A + B ).

3. Single Displacement Reactions: In these reactions, one element takes the place of another in a compound.

   You can imagine it like a swap:

   ( A + BC \rightarrow AC + B ).

4. Double Displacement Reactions: In these, two compounds swap parts with each other.

   It’s kind of like a dance-off:

   ( AB + CD \rightarrow AD + CB ).

5. Combustion Reactions: This happens when a substance reacts with oxygen, creating energy in the form of heat and light.

Each type of reaction shows how atoms can rearrange and connect in different ways.

This is what makes chemistry so exciting!
