State the term : (Do not give examples)
The substance that can remove hydrogen and oxygen atoms in the ratio of 2:1 (in the form of water) from the compounds.

State the term : (Do not give examples) A substance which contains water of crystallisation.

State the term : (Do not give examples) A solution where solvent is a liquid other than water.

State the term : (Do not give examples) When a substance absorbs moisture from the atmosphere, but does not form solution.

State the term : (Do not give examples) When a compound loses its water of crystallisation on exposure to dry air.

Give reason : The ratio of hydrogen and oxygen formed at the cathode and anode are 2 : 1 by volume.

Carbohydrates are compounds containing only carbon, hydrogen and oxygen having the atomic ratio of H : O as 2 : 1 . When heated in the absence of air, these compounds decompose to form carbon and water. a. If 310 g of a carbohydrates leaves a residue of 124 g of carbon on heating in absence of air, whatis the empirical formula of the carbohydrate?

Assertion : In the formation of water molecule, both hydrogen and oxygen atoms attain octet of electrons. Reason : Oxygen atom forms two ionic or electrovalent bonds with two hydrogen atoms.

How many different photons can be emitted by hydrogen atoms that undergo transitions to the ground state from the n=5 states?

If water sample are taken from sea, rivers or lake, they will be found to contain hydrogen and oxygen in the approximate ratio of 1 : 8 . This indicates the law of :
