Stoichiometry The net heat evolved or absorbed in a chemical process, i.e. total change in the enthalpy of the system is independent of the None of these Number of intermediate chemical reactions involved Temperature & pressure State of aggregation & the state of combination at the beginning & the end of the reaction None of these Number of intermediate chemical reactions involved Temperature & pressure State of aggregation & the state of combination at the beginning & the end of the reaction ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry With increase in the temperature of pure (distilled) water, its PH and pOH both increases PH decreases and pOH increases POH decreases and pH increases POH and pH both 4ecreases PH and pOH both increases PH decreases and pOH increases POH decreases and pH increases POH and pH both 4ecreases 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 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 The salt formed does not hydrolyse The strong base and strong acid reacts completely ANSWER DOWNLOAD EXAMIANS APP
