remembering that the barrier to rotation for a pair of eclipsing hydrogens is 4 kj/mol and 6 kj/mol for the eclipsing of a hydrogen and a methyl group what is the barrier to rotation for 2,2-dimethylpropane?

Agas has a volume of 0.7 l at 300 mmhg. what would be the new volume at 900 mmhg

Listen base your answer to the question on the information below.propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below.c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol.what is the correct structural formula for a molecule of methanethiol
