Iii. A sound wave can be modelled by using a slinky spring. A wavelength in this model is... a. the distance between a rarefaction and a compression.
b. the length of one compression.
c. the length of one rarefaction.
d. the distance between two rarefactions,

How could a student test the effect of removing heat from a gas that is stored in a sealed container? what must occur in order for matter to change states?

Idont understand it 1.what is the boiling point of a solution of 675 grams of ethylene glycol (c2h6o2) in 2.50 liters 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.
