Mixtures
Chemistry: Cambridge International GCSE Supplement, topic 12.1.2
Mixtures
Mixtures are made of 2 or more substances (elements or compounds) that haven't been chemically combined. Mixtures can be separated. Their chemical properties don't change because they have been mixed with another substance. Mixtures are common in everyday life:
Air
- Air is a mixture of gases, including oxygen, nitrogen and carbon dioxide.
Pasta and vegetables
- A bowl with both pasta and vegetables in is a mixture.
- This is because there have been no chemical reactions between the vegetables and the pasta.

Why are both air and a bowl of pasta and vegetables classed as mixtures?
