    Chemistry Mystery

    Hi, I know this is a physics/math forum, but I'd really like some help on this equilibrium question. :frown: Consider this reaction: 2NO2 <---> N2O2 If I increase the pressure, then the system will shift to the right, and thus the forward reaction rate will increase. After awhile, a...

    Stats Question, any help is appreciated

    I'm working on a question which requires you to understand the difference between Independence and disjoint events. The question is: Suppose 24% of a population have 4 years of college, and 15% are laborers/workers. From this, can you conclude that 0.24 x 0.15 = 0.036=3.6% of the population are...

    Chemistry Reaction Rates

    I came across this question on one of the practice papers I have and isn't sure about the answer, any help would be appreciated. The following reaction occurs at constant temperature and constant volume in a closed system: CaCO3(s) + 2H(ion)(aq) + 2Cl(ion)(aq) -> CO2(g) + H2O(l) +...

    Vector/1-D kinematics help

    Hi, can anyone explain to me in detail the logic/physics to this question? I posted it in general physics, & i guess it's the wrong forum. So i'll post my question here: A riverboat is trying to go north and cross a horizontal river to the other side. In the river, there is a current...

    Can someone help me?

    Hey, I'm a high school physics student and I came across this question on one of my practice papers that stumbled me quite a bit. It's a relatively simple relativity/vector question, but I can't understand why the correct answer is what it is. Can any1 help me? Here's the question: Suppose...
