A100.0 ml solution containing 0.923 gof maleic acid (mw=116.072 g/mol) is titrated with 0.265 m koh. calculate the ph of the solution after the addition of 60.0 ml of the koh solution. maleic acid has pkapka values of 1.92 and 6.27.

ph=

at this ph, calculate the concentration of each form of maleic acid in the solution at equilibrium. the three forms of maleic acid are abbreviated as h2m, hm−, and m2− which represent the fully protonated, intermediate, and fully deprotonated forms, respectively.

[m2−]=__m

[hm−]=__m

[h2m]=__m

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
