If you made up a solution of NaOH by adding 0.010 mole of solid NaOH to 1.0 liter of distilled water, what would be the concentration of the OH-(aq)?

physics
how far (in meters) will you travel in 3.0 minutes running at 6.0 m/s?

math
what square number is less than 64 but greater than 36? write a multilication sentence to solve.

calculus
solve (12/t)+t-8=0 (solving rational equations)

Chemistry
Thank you!

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.

Chemistry
NH3(g) + 2O2 (g) = HNO3 (aq) + H2O (l) How do I calculate the oxidation states of Nitrogen and figure out if it is reduced, oxidized or neither? My answer is 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,...

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)? 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?

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 inc...
