Hand lighters contain butane gas. If a hand lighter contains butane gas at 2.50 atm of pressure at 293°K, then what would be the new pressure of the lighter if it were left in a
hot car at 393°K? If the lighter was designed to hold only 3.00 atm of pressure, would
it explode? Assume the volume does not change, until it possibly explodes!

Which common material is an example of a polymer? (25 pts) a. steel b. plastic c. petroleum d. rubbing alcohol

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.
