Can you name ten chemical reaction that you see around you? and how does it happen?

Question

we need to make a record of 10 chemical reaction that we around. and we need to identify the observations that helps us realize that a chemical reaction is occuring.....

Answer 1

I'll name some reactions, but I don't have time for the "How they're happening" - You can figure that out on your own.

1.  Using a lighter - The flame part

2.  Starting a car engine

3.  Your bodies metabolism - Maybe a bit too complicated...

4.  Baking soda + vinager

5.  The ozone layer - Again perhaps too complicated...

6.  Coke and mentos

7.  Boiling an egg - It hardens inside

8.  I've run out... I'm sorry...  I need sleep...  Good luck

Answer 2

First, things that prove aa chemical reaction:

formation of a precipitate(a solid in a liquid), color change, formation of a gas (like air bubbles), and change in temperature.

The next thing about chemical reactions is that you CANNOT change them back...EVER!

That should help you distinguish chemical changes.

But, to help you out here are a few examples:

-wood burning

-metal rusting

-bread to toast

-alka seltzer

-food rotting

-digesting food

Answer 3

rusting of metal.

browning of apples & bannas & lettuce in open air.

photosynthesis of plants turning green.

fermetation of milk gone sour.

they way food cooks is whole chemical science.

That's as many as I can think of. Not sure is they are all true chemical reactions, but, they might give you a start.'

Answer 4

1.Acetylation

2.Chlorination

3.Bromination

4.Hydrogenation

5.Nitration

6.Esterifiction

7.Diazitisation

8.dehydrogenation

9.Cyclisation

10.Condensation and many more.Please see the below link,
