Suppose a 500. mL flask is filled with 1.3 mol of O, and 0.10 mol of SO3. This reaction becomes possible: 250,(g) + 0,(g) = 2so;(g) Complete the table below, so that it lists the initial molarity of each compound, the change in molarity of each compound due to the reaction, and the equilibrium molarity of each compound after the reaction has come to equilibrium. Use x to stand for the unknown change in the molarity of O,. You can leave out the M symbol for molarity. so, 0, so,

5. Sodium acetate can be formed from the metathesis/double replacement reaction of sodium bicarbonate and acetic acid. (See the Supplemental Information concerning metathesis reactions.) Determine the percent yield when 0.537 g of sodium acetate is obtained from mixing 15.0 g of NaHCO3 with 125 mL of 0.15 M acetic acid.

Suppose a 250. mL flask is filled with 0.70 mol of H2 and 1.1 mol of 12. The following reaction becomes possible: H2(g) +I2(g) — 2HI(g) =0 The equilibrium constant K for this reaction is 8.37 at the temperature of the flask. Calculate the equilibrium molarity of 12. Round your answer to two decimal places. Ом

For an experiment you are measuring the decomposition rate of organic matter, You have a large amount of CH402 in a container filled with 3.024 Lof water. You Created a saline environment by adding 2.4 g of sodium chloride, 3.6 g of calcium chloride, and 2.8 g of magnesium chloride before diluting. iron (1) oxide is available for the microbes to oxidize the matter into carbon dioxide by forming iron (II) aqueous ions. At the beginning of the experiment, you measure the pH using a probe to be 7.13. After 73 hours you measure the pH again and obtain 7.54. Assuming that the pH change is solely due to the oxidation of organic matter, what is the rate of organic matter decomposition in nanograms per hour?
