HELP PL ASAP im so desperate to get this done my course is due in 2 days and im sick so if you can help plz plz plz do if i dont finish it ill be forced to redue the whole course over again plzz im literally dyeing of stress and this cold is not helping In this project, you will conduct research on a substance called polypropylene and explore the relationship
between its properties and its molecular structure. You will provide an explanation of how the molecular
structure is well suited for commercial use. You will also create a model of polypropylene to display its
structure.

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

Draw any one of the skeletal structures of a 2° alkyl bromide having the molecular formula of c6h13br and two stereogenic centers. indicate chirality by using wedge and hashed wedge notation. lone pairs do not need to be shown.

How do you know when a chemical reaction has occurred
