Label each research topic below as an example of pure chemistry or applied chemistry. 1) developing a fire resistant fabric 2) reducing the active ingredient in a medication to minimize side effects 3) analyzing the compounds found in a soil sample from mars 4) measuring how much water expands upon freezing

These can be classified as

1) developing a fire resistant fabric  : it will involve the application of chemistry as this is not direct chemistry so this will be applied chemistry

2) reducing the active ingredient in a medication to minimize side effects :

This will involve the pure chemistry

3) analyzing the compounds found in a soil sample from mars  

This will involve again the analysis part hence it is pure chemistry

4) measuring how much water expands upon freezing

This is application of chemistry , hence applied chemistry

Pure chemistry:

Applied chemistry:

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
