I was given four molecular equations to balance. the next question states, "based on your balanced equation in #1, if 0.150g of copper was used to begin the experiment, calculate the mass of zinc required to reduce the CuSO4 obtained.(assume 100% completion of all intermediate steps and that no Zn(s) is lost in competing reactions.) show all work."
the balanced equations are
Idont even know how to start this problem can someone help.
