9) Use Hess’s Law and your answers from questions 7 and 8 (and research questions ) to calculate the heat of reaction for the burning of magnesium in oxygen. 10) Look up the heat of formation of magnesium oxide in your textbook.

Hess’s Law Labs By Austin Lee, Alayna Baron, Lily Zmachinski Introduction - In order to calculate the enthalpy change for the combustion of magnesium oxide (Mg (s) +1/2O 2(g) > MgO (s)), we used a coffee cup calorimeter to calculate the enthalpies of of two separate reactions.

Mar 03,  · I did a bunch of calculations and I got that q of water is a negative number. I'm then supposed to use this negative number in the calculation for the heat capacity of the calorimeter: Specific heat capacity of the calorimeter = q of water/(T of mix - T of initial) I got a negative number.
