Chemistry (Part-VI)

3Fe + 4H₂O → Fe₃O₄ + 4H₂

So it is clear that the number of water molecules in the left side is 4.

The leaching process is the operation of chemicals in the upper layers of the soil to dissolve in water, into the lower layers of the soil, or into the groundwater. The process of leaching within the chemical industry is commonly known as extraction.

PV = nRT

$PV=nRT$

Pmd=nRT

$P\propto d$

It is clear from the above that density is directly proportional to pressure. Therefore, pressure will increase with the increase in density and decrease with a decrease in density. It is clear from this that the molecular mass of a gas is twice its vapor pressure.

Solid carbon dioxide is known as 'dry ice'. Normally carbon dioxide remains in the gaseous state, but when the normal pressure of carbon dioxide gas is reduced, that gas shrinks to the solid state and it freezes like ice.
