yes some chemical reactions are harmful to us. as digestion of food, photosynthesis, decomposition of organic waste are some examples of the useful chemical reactions.
Anabolic reactions form organs and tissues of the body.

Two types of displacement reactions are known:- single displacement- double displacement
burning fuel reactions are useful because when energy is released and be converted into different forms they do useful work.. sorry find out your self about what useful works ......
Catabolism is breaking molecules down into smaller molecules (to get energy). You can remember this if you've ever had a cat -- they break things. Anabolism is the opposite: building things up (to make useful stuff). Now look up the definition of synthesis.
Transfer of protons
i think it is uranium
Combustion reactions are very valuable and useful to humans in several ways. One important combustion reaction takes place in an internal combustion engine.
Because they let us get around a lot eg like in our cars.But some reactions cause a lot of pollution so you cant use them to often. but other reactions are good!
4 useful chemical reactions are: fermentation, smelting combustion and electrolysis
make it useful for testing for signs of carbonation reactions in concrete
