Which test tube has largest amount precipitate? Why? (use terms such as limiting reactant and excess reactant to explain)
Do I just name the test tube that weighs the most and I need help with the explanation. I did not list the actual chemicals just need general statement.
The tube with the most precipitate is the one with the most solid stuff inside. You may be able to tell by looking. Did you need to put it in a centrifuge to get all the solds at the bottom? Picking the tube that weighs the most might not work if the weights of the empty test tubes or the liquid contents are unequal.
I cannot help you with your explanations since I have no idea what your lab experiment was, or the amounts of reactants that you used.
