What are liquid crystals? Give examples.
Liquid crystals are an intermediate state among liquid state and solid state. They exhibit some characteristic properties of both solids and liquids. The liquid crystal state has ?ow properties like ordinary liquids and they show anisotropy and double refraction just such as crystalline solids. Examples are Cholesteryl acetate and cholesteryl benzoate
when H+ is removed from any compound it forms conjugate acid. the addition of H+ ion gives conjugate base.
a solid weak acid i weighed, dissolved in water and diluted to exactly 50ml. 25ml of the solution is taken out and is tittrated to a natural endpoin with .10M NaOH. The titrated po

A first order reaction takes 69.3 minutes for 50% completion. Set up an equation for determining the time needed for 80% completion of this reaction.
which is more acidic among o-methoxy benzoic acid and m-methoxy benzoic acid Ans) O-methoxy benzoic acid is more acidic than m-metoxy benzoic acid.
why is hcl used in acid radical
Name: Cyclohexane Formula: C6H12 Molar mass: 84.16 g/mol Density: 779.00 kg/m³ As it''s density is less than that of water, it floats on water rather than sinking.
