Jonathan Sterling 2 CONCLUSIONS AND QUESTIONS 1. According to the balanced equation for the reaction used in this experiment, what is the ratio of moles of reacted to moles of produced? The equation is . Because there are no coefficients, the ratio would have to be 1:1 . 2. How many moles of are reacted in this experiment? How many moles of is produced? What is the ratio of moles reacted to moles of produced? Therefore, about
