Ammonium chloride and calcium hydroxide can react. The ammonia that is released in the reaction is collected in a gas syringe and sealed in. This gas is allowed to come to room temperature which is 32.0oC. The volume of the ammonia is found to be 182 ml. It is now placed in a water bath set at 47.6oC. What will be the volume reading after the syringe has been left in the bath for some time. (assume the plunger moves completely freely)?
Nitric acid is a key industrial chemical, largely used to make fertilizers and explosives. The first step in its synthesis is the oxidation of ammonia. In this reaction, gaseous ammonia reacts with dioxygen gas to produce nitrogen monoxide gas and water. Suppose a chemical engineer studying a new catalyst for the oxidation of ammonia reaction finds that 150. liters per second of dioxygen are consumed when the reaction is run at 195. °C and the dioxygen is supplied at 0.22 atm. Calculate the rate at which nitrogen monoxide is being produced. Give your answer in kilograms per second. Round your answer to 2 significant digits. kg x10 S
A canister containing 8g of helium gas (atomic mass 4.0U) was used to fill up party balloons. When the canister was full, the pressure in the gas was 3 atmospheres and its temperature was 27 degrees C. After filling the balloons, the pressure was seen to have dropped to 2 atmospheres and the temperature dropped to 17 degrees C. Exactly how many grams of helium gas were used to fill the balloons?
Use the necessary constant in solving this problem. See the second image.
In the Haber reaction, patented by German chemist Fritz Haber in 1908, dinitrogen gas combines with dihydrogen gas to produce gaseous ammonia. This reaction is now the first step taken to make most of the world's fertilizer. Suppose a chemical engineer studying a new catalyst for the Haber reaction finds that 715. liters per second of dinitrogen are consumed when the reaction is run at 153. °C and the dinitrogen is supplied at 0.18 atm. Calculate the rate at which ammonia is being produced. Give your answer in kilograms per second. Round your answer to 2 significant digits. kg S Continue dallall 80 x10 X 802 S ?

A flask contains a mixture of two gases: NO2 and Ne. The flask holds 0.519 mol of NO2 and an unknown amount of Ne. If the partial pressure of Ne is 0.43 bar and the total pressure in the flask is 0.83 bar, calculate the mass of Ne in the flask (in g). TIP: You don't need the volume of the flask nor the temperature to solve this problem. Express answer in 2 significant figures.

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
