Explanation:
Combustion of a compound is the reaction with oxygen , hence , the process of combustion is an oxidation reaction.
The carbohydrates contain more amount of oxygen as compared to the fats ,
Hence ,
carbohydrates , have a lot of oxygen contents , are are already partially oxidized , but fats have lower oxygen content .
Therefore ,
The partially oxidized carbohydrates are very difficult to oxidized in comparison to fats .
Ba2+ and Cu2+, and Sr2+ and Li+
Well, you could get the mass as

I have attached a photo of the structure.
You can get better at solving problems like this by practicing a lot!
Because cytoplasm is made of a jelly like consistent
