The Haber process is used to synthesize ammonia (NH3) on a large scale by the reaction of nitrogen gas with hydrogen gas as follows: N2 (g) + 3 H2 (g) → 2 NH3 (g) Consider a reaction between 9.9 L of nitrogen gas and 38.0 L of hydrogen gas at the exact same temperature and pressure. What volume of ammonia (in L) would you expect to be produced (at the exact same T and P as the reactants)? Express your...

References Liquid freon (CC12F2) is used as a refrigerant. It is circulated inside the cooling coils of older refrigerators or freezers. As it vaporizes, it absorbs heat. How much heat can be removed by 1.30 kg of Freon as it vaporizes inside the coils of a refrigerator? The heat of vaporization of Freon is 38.6 callg. Heat- cal References Suppose you put four 150-ml bottles of water into an ice chest filled with crushed ice. If the bottles were initially...

Ammonia gas is produced on a massive scale using the Haber-Bosch process. The reaction is: N2 (8) + 3H2 (8) À 2NH3 (8) AH = -92 kJ mol-1 (a) Write an expression for the equilibrium constant, Kp, for this reaction in terms of partial pressures. (b) Use the partial pressures given below to calculate the value of Kp at 700K, including its units. PM = 0.450 atmospheres P = 0.680 atmospheres Puu, = 0.152 atmospheres NIH (c) What would be...

1. The reaction N2 + 3 H2 2NH3 is used to produce ammonia. When 450. g of hydrogen is reacted with nitrogen, 2550 g of ammonia should be produced. If a chemist actually obtains 1,977 g of ammonia in the lab, what is the percent yield of this reaction? Report your answer to the correct degree of certainty. Do not included units (% yield is understood). 2.Calculate the volume of 2.12 moles of nitrogen gas at temperature of 31.7 oC and a pressure of...

Calculate the density of oxygen, O2, under each of the following conditions: STP 1.00 atm and 35.0 ∘C Express your answers numerically in grams per liter. Enter the density at STP first and separate your answers by a comma. To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 4.8-L bulb, then filled it with the gas at 1.40 atm and 30.0 ∘C and weighed it again. The difference in mass was 7.5 g ....
