    Determine the homolytic C-H bond strength in CH3OH employing the following data.

    DfH (CH3OH) = -201.6 kJ mol-1 DfH (H) = 218 kJ mol-1 DfH (HBr) = -36 kJ mol-1 DfH (Br) = 111.9 kJ mol-1 CH3OH + Br  CH2OH + HBr k(300K) = 1 x 106 M-1s-1; k(350K) = 4 x 108 M-1s-1 CH2OH + HBr  CH3OH + Br k(300K) = 1 x 107 M-1s-1; k(350K) = 7.7 x 108 M-1s-1 Any help would be...

    Chemistry What is the Molecular Formula of Gallium Oxide from 1.25g Ga and 1.68g GaxOy?

    Thank you for the help but can you please explain how to start it off fully, I tried to solve it but messed something up and got an answer that was not even close to the actual. As long as you explain how to start it off I should be able to do the rest myself. Thank you

    Chemistry What is the Molecular Formula of Gallium Oxide from 1.25g Ga and 1.68g GaxOy?

    The question is as follows: Gallium Oxide GaxOy forms when gallium is combined with oxygen. Suppose you allow 1.25 grams of gallium (Ga) to react with O2 and obtain 1.68 g of GaxOy. What is the formula of the product? Can you explain how to solve this problem any help is appreciated, thank you.
