2A1+ 3Br2 --> 2A1Br3 The reaction shown above is performed in a lab. When 10.7 g of Br2 is reacted with excess
aluminum, 11.3 g of AlBrz is actually produced in the lab. What is the percent yield of this lab
reaction? (Hint: you will need to find the theoretical yield before you calculate the percent yield.

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
