Stoichiometry A metal oxide is reduced by heating it in a stream of hydrogen. After complete reduction, it is found that 3.15 gm of the oxide has yielded 1.05 gm of the metal. It may be inferred that the Atomic weight of the metal is 2 Equivalent weight of the metal is 8 Atomic weight of the metal is 4 Equivalent weight of the metal is 4 Atomic weight of the metal is 2 Equivalent weight of the metal is 8 Atomic weight of the metal is 4 Equivalent weight of the metal is 4 ANSWER DOWNLOAD EXAMIANS APP

Stoichiometry The density of a gas 'X' is twice that of another gas 'Y'. If the molecular weight of gas 'Y' is 'M'; then the molecular weight of the gas 'X' will be M 2M M/4 M/2 M 2M M/4 M/2 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Heat of neutralisation of a strong acid and strong base is always a constant value, i.e., 57 KJ/Kg mole. This is because The strong base and strong acid reacts completely The salt formed does not hydrolyse Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts in aqueous solution The strong base and strong acid reacts completely The salt formed does not hydrolyse Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts in aqueous solution ANSWER DOWNLOAD EXAMIANS APP
