The chemical changes in matter from the list you provided are:
- **Bleaching your hair:** This process involves a chemical reaction that changes the structure of the hair's pigment.
- **Lighting a match:** The process produces a chemical reaction that converts the matchstick material into ash and releases gases.
- **Letting fruit rot:** This process involves decay and decomposition, which are chemical changes as the composition of the fruit breaks down.
The other two options, mixing lemonade powder in water and mowing the lawn, do not involve chemical changes; they are physical changes. Mixing lemonade powder in water does not alter the chemical composition of the ingredients, and mowing the lawn does not change the nature of the grass itself.
