Re: Quiz 2 Winter 2017
Can someone explain why question 10 is false? I thought half-lives are always the same. I am also confused by this question. I know that the equation is second-order, but do not understand why the decomposition would take different amounts of time. For number 10 you use the integrated rate law for ...

Re: Oxidation States
In that example you can see that C appears in two different compounds in the reactant and product (C2H5OH and C2H4O). You can calculate the charge of the C in C2H5OH because the charge for H is +1 and O is -2, so in order to neutralize the overall charge, C is -1. Then you do the same for the C in C...

Re: HW Problem 8.37 Need Help
At standard temperature and constant pressure, the enthalpy of vaporization is the value needed to vaporize 1 mol of a given molecule. For 8.37 a) you can create a proportion in order to solve for the enthalpy of vaporization: 0.579 mol CH4 / 4.76 kJ = 1 mol CH4 / X, and then solve for X. You also d...
