Consider the reaction between 50.0 mL of 0.200 M sodium hydroxide and 75.0 mL of 0.100 M hydrochloric acid. After the reaction has gone to completion, which of the following statements is correct? Select one: O A. The concentration of Na+ (aq) is still 0.200 M because it is a spectator ion O B. The concentration of Na+ (aq) is equal to the concentration of CI- (aq) O C. The concentration of Na+ (aq) is greater than the concentration of OH(aq) O D. More than one of the statements is correct O E. NaOH is the limiting reactant Consider the reaction of ammonia with oxygen gas to produce nitrogen monoxide and water. When 3.5 mol of ammonia reacts with 3.9 mol of oxygen gas, how many moles of water are produced? Assume the reaction goes to completion. Do NOT include units in your answer. If you round during your calculation, be sure to keep at least three (3) decimal places. Report your answer to one (1) decimal place. Answer:
