Homework Statement [/b]
I need to balance the following redox equation
K2Cr2O7 + H2C2O4 [2H2O] ----> K[Cr(C2O4)2(H2O)2]2H2O + CO2 + H2O
. The attempt at a solution[/b]
so far I have this but I am stuck
14H30{+} + Cr2O7{2-} + 3C2O4{2-} --> 2Cr{3+} + 21H2O + 6CO2
Hi
I am having a lot of trouble with this problem. I don't actually know where to begin.
A box with a square base and open top must have a volume of 62,500 cm3. Find the dimensions of the box that minimize the amount of material used.
Need to find:
