  1. I’ve seen Hess’ law problems where you have to get rid of the fractions in the original equation, and then proceed however at the end of the problem you have to divide by the number that you applied to the coefficients in the beginning equation provided. Example: 1/2 H2 + 1/2 Cl2—-HCl. I did this problem for hours until I realized that I needed to double the coefficients, and then use the given formulas AND then divide my answer by two.

    IS this the rule in situations like this?

  2. Where can I find the quizzes that are associated with the lectures. Especially Gen Chemistry? Thank you! Also Chad my fiance works for GoDaddy and he is the supervisor for the hosting department and perhaps he can help your site out? All the best,
