Stoichiometry Addition of a non-volatile solute to a pure solvent Increases its freezing point Both B and C Increases its boiling point Decreases its freezing point Increases its freezing point Both B and C Increases its boiling point Decreases its freezing point 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 Only OH⁻ and H⁺ ions react in every case The salt formed does not hydrolyse The strong base and strong acid reacts in aqueous solution The strong base and strong acid reacts completely Only OH⁻ and H⁺ ions react in every case The salt formed does not hydrolyse The strong base and strong acid reacts in aqueous solution The strong base and strong acid reacts completely 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 1335 1735 1525 1225 1335 1735 ANSWER DOWNLOAD EXAMIANS APP
