When adding and subtracting, the answer must have the same number of digits to the right of the decimal as the original number value having the fewest number of digits to the right of the decimal point.
Add and subtract as indicated. Round off when necessary.
1) (4.32x10^3cm)-(1.6x10^4mm)
2) (2.12x10^7mm)+(1.8x10^3cm)

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.
