What would be the heat released when an aqueous solution containing 0.5 mole of `HNO_(3)` is mixed with 0.3 mle of `OH^(-)`? (Enthalpy of neutralisation is -57.1 kJ)A. 28.5 kJB. 17.1 kJC. 45.7 kJD. 1.7 kJ |

Answer» Correct Answer - B 0.5 mole of `HNO_(3)-=0.5` mole of `H^(+)` and 0.3 mole of `OH^(-)` `0.5H^(+)(aq)+0.3OH^(-)(aq)to0.5H_(2)O(l)` `DeltaH=0.3xx57.1=17.13kJ` |
