86.14 ml of an acid solution was needed to neutralize 30.24 ml of a base solution of unknown concentrations. a second trial is run but this time 30.24 ml base solution is diluted to a total volume of 50.00 ml before starting the titration. how many ml of the acid solution are needed to neutralize it?
a) 45.26 ml
b) 86.14 ml
c) 61.11 ml
d) 52.10 ml

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.
