When a substance becomes part of a mixture, its chemical properties ONLY change if the resulting mixture is homogeneous. Otherwise nothing happens to the properties.
Step-by-step explanation:
The formula of a selected pure substance doesn't amendment simply because it becomes a part of a mix. Chemical properties can amendment in a very mixture. If you've got a mix of water and alcohol, the melting point are below 0C. That doesn't mean that water now not freezes at 0C, it simply means that the mixture of water and alcohol doesn't freeze at 0C.
