What would be the heat released when an aqueous solution containing 0.5 mol if HNO_(3) is mixed with 0.3 mol of OH^(-1) (enthalpy of neutralisation is -57.1 kJ)

Answer»

28.5 KJ
17.1 kJ
45.7 kJ
1.7 kJ

Solution :0.3 mole `OH^(-)`, NEUTRALIZE 0.3 mole of `HNO_(3)`
Evolved HEAT, `=57.1xx0.3=17.13 kJ`.
