1.) Calculate the pH of a solution formed by mixing 200.0 mL of 0.300 M NaHSO4 with 200.0 mL of 0.200 M Na2SO4 and 1.0 ml 1.00 M NaOH. The Ka2 for H2SO4
is 1.2 x 10^-2.

What is the effect of returning nuclear reactor cooling water back into bodies of water?

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.
