If 7.50 L of water vapor at 50.2 °C and 12.26 kPa reacts with excess iron, how many grams of iron(III) oxide are produced? 2 Fe(s) + 3 H,O(g) - Fe,0,(s) + 3 H,(g) 2.02 iron(III) oxide produced: Incorrect

5.72 A sample of zinc metal reacts completely with an excess of hydrochloric acid: Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g) The hydrogen gas produced is collected over water at 25.0°C using an arrangement similar to that shown in Figure 5.15. The volume of the gas is 7.80 L, and the pressure is 0.980 atm. Calculate the amount of zinc metal in grams consumed in the reaction. (Vapor pressure of water at 25°C = 23.8 mmHg.)

Ammonia burns in oxygen in the presence of a platinum catalyst to produce nitrogen monoxide and water by the following reaction: 4NH3(g) +50₂ (g) 4NO (g) + 6H₂O (1) If 9.00 g of ammonia is burned in excess oxygen, what is the mass of water that will be produced and the volume of NO gas if the reaction was carried out at 25 °C under a pressure of 100 kPa?

Refer to the following equation: Mg (s) + 2HNO3(aq) -> Mg(NO3)2 (aq) + H2 (g) A reaction between 0.359 grams of Mg and 21.12mL of a 0.450M HNO3 solution was conducted in a room witht he following conditions: 27.5 degrees Celius, 723mmHg of atospheric pressure. If .15mL of H2 were collected over water (by the water displacement method), calculate the percent yeild of the reaction. (Pressure H2O at 27.5 degrees Celius = 27.82 mmHg)
