2H20(l) = 2H2 (g) +O2 (g) For the above, if 1.50 mg of water is decomposed, what mass of hydrogen is procduced? (1 Mg=10^6g=1 metric ton)? What is the answer and what is the best way to solve this?

Thank you for the link! Here is my answer below. I am not sure if I am figuring it right. Please advise. NH3(g) + 2O2 (g) = HNO3 (aq) + H2O (l) N is -3,H3 is +1, 2o2 is 0, H is +1, N is X ??, O3 is -2, H2O is -2 Therefore X=-2 I am not sure how to figure N. Is it X or is N include NO3? and it is Oxidized

Thanks for the info. I came up with 0.1678475161 and rounded it to .17 mg H2. Am I on the right track and did I include the correct amount sig figs?

That is what I am confused about. Do you separate the N out of the HNO3? So, it is H+1, N -3, O3 is -2? I guess I am making harder then it is.

Thank you!

Number 1 is really a not c. Because i put c and it got me a 95 and not a hundred. :(

I think the answer is c .
