Calculate the binding energy per nucleon of a 13C carbon atom if the mass of a 13C carbon atom is 13.003355 amu, the mass of a proton is 1.007825 amu, and the mass of a neutron is 1.008665 amu.

Is this a scientific model? use complete sentences to explain why or why not. a graphic organizer showing the water cycle i need : ( asap i go it never mind

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

Why is the structure of molecule important to its function?
