The electrolysis (decomposition) of water produces hydrogen gas at the rate of 30.0 mL/min.
A) Write a balanced chemical equation for this reaction and include phase designations.
2H2O(aq)> 4H2(g)O2(g)
Is whatever I've done above correct?
B) What volume of hydrogen gas can be produced in 4.5 min?
30.0 ml
_______ = 66.6v.
4.5 min
Is this right?
C) Based on your balanced equation, predict the rate of oxygen gas produced.
I am unsure of this question. I don't get it.

A looks ok but you omitted the + sign between the products.
B doesn't look right to me. The units don't seem to be right. I would think if the production is 30 mL/min then it would be 30 mL/min x 4.5 min (note the min calcel to leave mL which is what you want) = 30 x 4.5 = ??
C. Looking at the coefficients, I would think O2 would be produced at 1/4 the rate of H2 since the coefficients are 4/1 in favor of hydrogen.
