Answer the following questions and attach with your prelab write-up. a) what is the [h+ ] in m, mm, and µm in a solution that has ph 5.5? b) which formula would you use if you are to calculate the ratio of dissociated vs. un-dissociated forms c) when sufficient h+ is added to lower the ph by one unit, what is the corresponding increase in [h+ ]? explain with example. d) calculate the ph of 2.56x10-3 m monobasic base solution (assuming complete ionization) e) identify sources of acid and base components of the following salts: i) sodium chloride ii) potassium acetate iii) ammonium chloride

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
