Stoichiometry At room temperature, the product [H⁺] [OH⁻] in a solution is 10⁻¹⁴ moles/litre. If, [OH⁻] = 10⁻⁶ moles/litre, then the pH of the solution will be 10 12 6 8 10 12 6 8 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry One mole of methane undergoes complete combustion in a stoichiometric amount of air. The reaction proceeds as CH₄ + 2O₂ → CO₂ + 2H₂O. Both the reactants and products are in gas phase. ΔH°298 = - 730 kJ/mole of methane. If the average specific heat of all the gases/vapour is 40 J/mole.K, the maximum temperature rise of the exhaust gases in °C would be approximately equal to 1525 1225 1735 1335 1525 1225 1735 1335 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 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 The strong base and strong acid reacts completely ANSWER DOWNLOAD EXAMIANS APP
