## Applications of Chemistry The knowledge of chemistry can be applied in the following areas: 1. **Hospitals:** The knowledge of chemistry makes it possible for people to involve in chemical research and technology which lead to the production of medicine that we use today. 2. **Military:** Chemistry contributes to the discovery and description of the theoretical bases for the behaviour of chemical substances such as explosives used by the military. The gunpowder used in the earliest guns was made by mixing sulphur, charcoal and potassium nitrates ($KNO_3$); compounded by early chemists. ## Equipment 1. **Spatula:** Made of iron, it is used to transfer solutions in drops during experiments. It is like a spoon.
