importance of elements and compound?

elements and compounds?

um oxygen (O2) and carbon dioxide (CO2) plants need them for photosynthesis

if you’re interested the formula for photosynthesis is

6CO2 + 6H2O >light> C6H12O6 + 6O2

and.. im too lazy to write anymore

Uranium (U) – fuel in nuclear reactors

Calcium oxide (CaO) – used in preparation of cement

hydrogen (H2) – most common element in universe. used to obtain energy during hydrolysis: 2(H2) + O2 =2(H2O) +energy

It is also used in the manufacture of ammonia (NH3)

Ammonia (NH3)- colourless, pungent gas, highly soluble in water. It is an important refrigerant & is used to produce fertilizers & explosives.

Sulphur (S) – tasteless, odorless, light yellow nonmetallic element. The most important use of sulfur is in the manufacture of sulfur compounds, such as sulfuric acid, sulfites, sulfates, and sulfur dioxide. Also employed in the production of matches, vulcanized rubber, dyes, and gunpowder.

Sulphuric acid (H2SO4) – It is a corrosive, oily, colorless liquid. The concentrated acid destroys skin and flesh, and can cause blindness if it gets into the eyes. The best treatment is to flush away the acid with large amounts of water. The use of sulfuric acid is for making fertilizers, paints and pigments. One of the few consumer products containing sulfuric acid as such is the lead storage battery, or car energizer.

Hope this helps
