mixture with baking soda is heated and has a mass loss of 0.325 g. Refer to Example Exercise 14.2 and calculate the percentage of NaHCO3 in the mixture. 1 mol H2 CO3 62.03 g H2 CO3 2 mol NaHCO3 1 mol H2 CO3 84.01 g NaHCO3 1 mol NaHCO3 [?B1] g H2CO3 x = [?B2] g NaHCO3 %D Percentage of NaHCO3 in the mixture = [?B3] %

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
