    Two hydroxides doesn't matter in this problem

    I'm having trouble understanding why the fact that there are two hydroxides doesn't matter in this problem. What volume of 0.150-molar HCl is required to neutralize 25.0 milliliters of 0.120-molar Ba(OH)2? I thought the setup would look like this simple enough: (25.0 mL)(.120 M)(2) =...

    Chemical Kinetics - Rate Laws and Mechanisms

    So, for (c), wouldn't it also be half of the initial concentration of NO, .02? And, as far as (d) goes, I know that choice I is correct, but I just don't understand why.

    Chemical Kinetics - Rate Laws and Mechanisms

    Homework Statement This is straight off an old AP Exam, but I can't seem to find it online so I'm hoping you all can help me out. 2 NO(g) + Br2(g) --> 2 NOBr(g) The following results were obtained in experiments designed to study the rate of the reaction above. Experiment Initial...
