    Determination of the enthelpy of combustion of Magnesium using Hess's law

    dang...ouch 38% error well...i guess that's what you get when you use Styrofoam insulators...

    Determination of the enthelpy of combustion of Magnesium using Hess's law

    Homework Statement ok so I'm trying to find the change in enthalpy for this reaction: Mg(s) + (1/2)O2--> MgO(s) I've done the lab to find the temperatures of certain reactions, these were: 9.70 Celsius for the reaction Mg(s) + 2HCl(aq)--> MgCl2(aq) + H2(l) 7.60 Celsius for the reaction...
