Nitric acid is often manufactured from the atmospheric gases nitrogen and oxygen, and hydrogen prepared by reforming natural gas, in a two-step process. In the first step, nitrogen and hydrogen react to form ammonia: N₂(g) + 3H₂(g) 2 NH3 (8) In the second step, ammonia and oxygen react to form nitric acid (HNO3) and water: NH3 (g) + 20₂(g) - HNO3(g) + H₂O(g) Suppose the yield of the first step is 81.% and the yield of the second step is 88.%. Calculate the mass of hydrogen required to make 3.0 kg of nitric acid. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits. 0 x10 00 X

Your lab partner accidentally mixed some sodium chloride with your sample of Epsom salts (MgSO₄･7H₂O). You want to make a standard solution of magnesium ion, and this is the only sample of a magnesium salt you have. To determine the amount of magnesium salt in the mixture, you heat 100.00 g to drive off the water of hydration and find that the anhydrous mixture has a mass of 55.25 g. What is the mass in grams of the original salt mixture that you must add to 1.000 L of water to make a 0.1000 M solution of Mg²⁺ ion?
