Stoichiometry For a neutral solution (pH = 7), the value of[H⁺] [OH⁻] is equal to 1 < 1 > 1 1 < 1 > 1 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 salt formed does not hydrolyse The strong base and strong acid reacts completely The strong base and strong acid reacts in aqueous solution Only OH⁻ and H⁺ ions react in every case The salt formed does not hydrolyse The strong base and strong acid reacts completely The strong base and strong acid reacts in aqueous solution Only OH⁻ and H⁺ ions react in every case ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry A butane isomerisation process produces 70 kmole/hr of pure isobutane. A purge stream removed continuously, contains 85% n-butane and 15% impurity (mole%). The feed stream is n-butane containing 1% impurity (mole%). The flow rate of the purge stream will be 6 kmole/hr 5 kmole/hr 3 kmole/hr 4 kmole/hr 6 kmole/hr 5 kmole/hr 3 kmole/hr 4 kmole/hr ANSWER DOWNLOAD EXAMIANS APP
