    Chemistry p41: How'd it go peeps?

    Wait, what?! I got a different reaction. 2KBr + ClF=KCl + KF + Br2. Because both are more reactive than bromine.

    Sorry bromine went from -1 to 0 not +1. Displacement is definitely right.

    Chemistry p41: How'd it go peeps?

    I called it a redox reaction. Cl went from +1 to -1 and br from -1 to +1.

    Chemistry p41: How'd it go peeps?

    Liquify the gases before doing it? Hell, I don't know. Got the Ksp right then. Oh that's a good point. I wrote about cross links and the polymer being more compact.

    Chemistry p41: How'd it go peeps?

    Yeah I wrote that longer hydrocarbons would produce more CO2 during combustion. I wrote about limewater, fractional distillation and squeezed in gas liquid chromatography as well. Damn those electrochemistry questions! Anyway I wrote no effect for when it was added to the iron half cell because...

    The last question. What was the reason the shale gas gave less carbon dioxide? And how did you remove it?
