A student (Becky) is helping a friend (Taylor) solve a stoichiometry problem. Taylor needs to know how many liters of nitrogen monoxide (NO) gas are created at STP when 150 g of solid copper reacts with excess nitric acid. 3Cu(s) + 8HNO3 (aq) 3Cu(NO3), (ag) + 4H,0(1) + 2NO(g) Taylor knows they should put 150 g Cu down first, and they also know they need to convert from grams to something else. Becky provides a clue to Taylor: they will need 3 conversion factors (which are empty, below). What does Taylor need in order to complete the third conversion factor? 150 g Cu 1 Coefficients from the balanced equation (molar ratio) The molar mass of nitrogen monoxide O The molar mass of copper Avogadro's number The STP volume of gas (22.4 L/mol)

Hydrogen peroxide decomposes releasing oxygen with iodine as catalyst. When 50.0 mL of 35% hydrogen peroxide (density 1.11 g/mL) was diluted with 100 mL of water, and then decomposed, 5.1_L of oxygen were collected at STP. What was the percent yield of this procedure? Please clearly show your calculations.
