Please help um if you can only answer one its fine 1. explain what happens when an electron moves from a lower energy level to a higher level of energy. an electron needs 1.2 eV of energy to jump from energy level 1 to energy level 2. Predict what would happen if the electrons receive 1.0 eV of energy. explain your reasoning.

2. differentiate between the magnetic quantum number and spin quantum number. discuss what each represents and the possible values.

Which feature do highland climates have that lower elevation areas do not?

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
