Chemistry plays a crucial role in our life. Even in our body chemical reactions occur. these are as follows-
..firstly even many elements which are present our body are also mentioned in periodic table ( carbon, iron ( haemoglobin), calcium( bones and tooth), Co2 and O2, Hydrogen and chlorine ( HCL) etc-etc.)
..acid present in our stomach ( hcl ) breakdown complex forms of food into simpler ones so that they can be digested easily.
...Even chemistry has importance in our mouth, our teeth are made up of calcium. when ph value of our mouth goes less than 5.5 then our tooth decay starts.
... we use baking soda for neutralizing the affect of pain caused by ant sting and bee sting.
..... we use vinegar and citric acid to neutralize affect of pain caused by hornet sting ( its sting is basic in nature).
.... Hcl is used in inverter batteries.
.... acids or digestive juices also have chemical formulas ( insulin, bile etc.)
when our brain sends message to our organ to move this message is actually a chemical which is injected in muscles so that contraction or extension of muscles occurs.
... Even rusting of iron occurs by reaction of atmosphere components on it, now you will think whats importance of this answer is that ' now bridges are made of iron. they will get rust. by this we will know that iron is damagad and we apply to them paints etc so tjat we can prevent them from rust. if this action wasnt there then a bridge would breakout without any warning and can take heavy toll of life.'
.... we apply paints, greese , lubricants, and galvanize them which prevents them from rusting. it can save our money and time too.
.. Even medicines are based on chemistry.
I think its enough. hope it will help. please mark brainliest if you like it.
