Suppose a chemical engineer studying a new catalyst for the Claus reactions finds that 493. litres per secnd of dioxygen are consumed when the reaction is run at 183 degree celcius and the oxygen is supplied at 0.76 atm. calculate the rate at which sulfur dioxide is being produced. give your answer in kilograms.

In order to produce solid iron, it first must bc processed from its orc, Fe2O1, in a blast furnace. During operation, CO gas (flue gas) is introduced into the furnace at 1650 °C and a pressure of 250 kPa. In this process flue gas reduces iron to its elemental form in the following reaction: 41. Fe;O30) COg Fe+ COz At one point in this process 256.0 L of CO was used to reduce iron ore. Assuming a complete reaction, how many grams of solid iron can be produced. Balanced chemical equation: Mass of Fe (in grams)

Three bulbs are connected by tubing, and the tubing is evacuated. The volume of the tubing is 49.0 mL The first bulb has a volume of 58.0 ml and contains 6.07 atm of argon, the second bulb has a volume of 250 ml. and contains 1.62 atm of neon, and the third bulb has a volume of 27.0 ml. and contains 7.72 atm of hydrogen. If the stopcocks (valves) that isolate all three bulbs are opened, what is the final pressure of the whole system in atm? Answer:

Most of the sulfur used in the United States is chemically synthesized from hydrogen sulfide gas recovered from natural gas wells. In the first step of this synthesis, called the Claus process, hydrogen sulfide gas is reacted with dioxygen gas to produce gaseous sulfur dioxide and water. Suppose a chemical engineer studying a new catalyst for the Claus reaction finds that 421. liters per second of dioxygen are consumed when the reaction is run at 280. °C and the dioxygen is supplied at 0.35 atm. Calculate the rate at which sulfur dioxide is being produced. Give your answer in kilograms per second. Be sure your answer has the correct number of significant digits. 00 S X 6 000 Ar B
