In the early days of organic chemistry, scientists had only a few techniques available to them for the analysis of compounds. These included smell, taste, color, and physical state (gas, liquid, or solid). With this in mind, suggest how they could differentiate between the compounds in the following pairs. You will need to research the properties of the different chemicals using books and the internet. Share your answers in a post with others in your group. Comment on the posts of at least two other students - have they correctly identified tests that would allow them to differentiate the compounds?

Atrain travels 74 kilometers in 3 hours, and then 81 kilometers in 5 hours. what is its average speed?

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
