Homework Help: Chemistry

Posted by Hannah on Monday, February 13, 2012 at 3:50pm.

I had to perform an experiment using a coffee-cup calorimeter to determine the enthalpies of two seperate reactions. For part 1 we worked with magnesium metal, and magnesium oxide. Data was collected and now I need to find the q, heat transferred for both magnesium and magnesium oxide.

For magnesium the mass of rxn mixture was 24.371g and for magnesium oxide it was 25.036g.

I think that I am suppose to use the q=mc delta T equation and the rxn value but I am not sure quite how to do this. Do I just plug the rxn number into the equation along with the delta T value I got for both?
