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 strong base and strong acid reacts completely The salt formed does not hydrolyse The strong base and strong acid reacts in aqueous solution Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts completely The salt formed does not hydrolyse ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Pick out the wrong unit conversion of calorific value. 1 kcal/m³ = 0.1124 BTU/ft³ 1 kcal/kg = 1.8 BTU/lb = 4.186 kJ/kg 1 BTU/lb = 2.3 kcal/kg 1 BTU/ft³ = 8.9 kcal/m³ = 0.038 MJ/m³ 1 kcal/m³ = 0.1124 BTU/ft³ 1 kcal/kg = 1.8 BTU/lb = 4.186 kJ/kg 1 BTU/lb = 2.3 kcal/kg 1 BTU/ft³ = 8.9 kcal/m³ = 0.038 MJ/m³ ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry A car tyre of volume 0.057 m³ is inflated to 300 kPa at 300 K. After the car is driven for 10 hours, the pressure in the tyre increases to 330 kPa. Assume air is an ideal gas and Cv for air is 21 J/mole.K. The change in the internal energy of air in the tyre in J/mole is 760 380 880 630 760 380 880 630 ANSWER DOWNLOAD EXAMIANS APP
