Answer 2

Answer:

In chemistry,

Substance are divided into

Metals and Non-Metals

Metals like Iron are used in construction sites i.e. in building, bridges. It's due to the high tensile strength.

Metals like Copper are used as electric wires in our houses. Being good conducter of electricity, it's used also in cables.

Non Metals like Calcium , Phosphorus etc are very important for our body. Infact , our bones contain Calcium in it.

Another important non metal without which life is impossible, is Oxygen. As you know its much needed Gas for our respiration.

Now we will take about how acid and bases are useful,

Acid like HCl are present in our stomach in lesser amounts but are needed for digestion.

NaCl is the common salt, which is added by all moms to increase the taste of curry for their children.

Bases like Mg(OH)² are needed for our body in the time of acidity. When the amout of HCl increase, this mild base nullify it and minimising the painful effect.

Like this way, CHEMISTRY is used in every spheres of our life.
