Name CHEM 111-01 Date: February 22 Due Date: March 1 Recall the stoichiometric coefficients (the numbers before the individual species) in a balanced chemical reaction refer to the number of moles of that species involved in thhe chemical reaction. A balanced chemical equation shows the molar relationship between all of the reactants and products. Now, given the following chemical equation: (5 points) a. Is this equation balanced? (Yes / No) b. How many moles of HNO, are required to react with 6 moles of Cu? c. How many moles of Cu(NO,), are produced when 3 moles of Cu react? d. How many moles of Cu must react to produce 4 moles of NO? e. If 4 mole of NO are produced, how many moles of H2O are also produced? You must show your work for the On a separate sheet problems. II. (5 points each) 2. The overall equation for the metabolism of sucrose, C,H220,, is a. b. How many moles of CO, are produced when 1 g of sucrose is metabolized? How many grams of CO2 are produced when 1 g of sucrose is metabolized? Lithium hydroxide is used in the space program to remove carbon dioxide (from respiration in spacecraft. Specifically, lithium hydroxide, LiOH, reacts with carbon dioxide, CO2. to for 3. lithium carbonate, Li,CO, and water What mass of CO, can be absorbed by 15 of LiOH? 4. Urea, (NH2),CO, can be prepared by reacting ammonia, NH,, with carbon dioxide. 2 NH, + CO2 (NH2)2CO + H2O â If 12.24 g NH, are treated with 22.4 g of Co, a. Identify the limiting reactant b. What mass of urea can be produced?
