18. Consider the balanced combustion reaction below in which 6.67 mL C3H7QH (d = 0.804 g/cm) reacts in the presence of 9.04 g O2 gas yielding 2.45 mL of H2O (density = 1.00 g/cm*). Report your answers in standard notation. 2 C3H7OH (I) + 9 O2 (g) + 6 CO2 + 8 H20 (a) What is the limiting reactant? A. C3H7OH B. Oz (b) What is the theoretical yield of HzO (in grams)? | (c) What is the percent yield of H20? | 19. A scientist goes to lab to synthesize NasAlFs via the balanced chemical reaction below. If they need 780. grams of NasAlFe, and the overall percent yield is 45.4 %, how much Al2Os (in grams) is needed? You may assume NaQH and HF is in excess here. Report your answer in standard notation. 6 NaOH + AlzO3 + 12 HF 2 NasAlFe + 9 H20 |
