When a solution of KOH is neutralized by hydrochloric acid, the solution gets hot.
Calculate the change in heat of the solution (in J).
Mass of combined solution = 45.0 g
Temperature change of the solution = 23.5 K
Specific heat capacity of the solution = 4.18 J/g. K

Benzonitrile (c6h5cn) is reduced to two different products depending on the reducing agent used. treatment with lithium aluminum hydride followed by water forms k, which has a molecular ion in its mass spectrum at 107 and the following ir absorptions: 3373, 3290, 3062, 2920, and 1600 cm-1. treatment with a milder reducing agent forms l, which has a molecular ion in its mass spectrum at 106 and the following ir absorptions: 3086, 2850, 2820, 2736, 1703, and 1600 cm-1. l shows fragments in its mass spectrum at m/z = 105 and 77. propose structures for k and l and choose an explanation for how this could be concluded.
