PLEASE HELP QUICKLY!! Version A
During a lab experiment, Helvetica created 0.436 g of hydrogen gas by reacting 15.00 g zinc
metal with an unlimited amount of hydrochloric acid:
Zn + 2HCI → ZnCl2 + H2
Mr. Poindexter indicated that in order to receive a passing grade for this lab, students must
produce enough hydrogen gas that falls greater than or equal to a 97 percent yield.
What is the theoretical yield based off the information given?
What was the percent yield that Helvetica achieved?
Did Helvetica receive a passing grade on this lab?
