Q. What is Calcinations process?
This is fie method of heating the concentrated ore in a limited supply of air to a high temperature but under the fusion temperature. In calcinations, volatile constituents of an ore are expelled. Hydrated and Hydroxide ores lose their water forming metal oxides. In case of carbonate ores, carbon dioxide is lost and metal oxides are made.
Another way to show that water pressure increases with depth Search a tall tin can. Punch holes up the side of the can about 3 cm apart. Put a strip of adhesive or plastic tape
Explain experimental evidence to demonstrate the existence of ferromagnetic domains. Temperature increases, thermal motion, or entropy, competes with ferromagnetic tendency for

what is the difference between mirror image and optical isomerism?
explain about law of chemical combinations in about 200 words?
1)Aniline is more basic because of the strong electron withdrawing effect of the carbonyl oxygen on the amide of acetanilide. 2)Aniline is more basic because of the strong electro
The formation Alkenes by the dehydration of alcohols (using concentrated H 2 SO 4 ) the hydrogen atom will be separate (to remove as water) from the adjacent carbon atom correlated
