To calculate X using the equation [m(h2o)+X]Cwater+water=-1(m(ice water)Cwatertice water) the variable X must be isolated and doing so we were than able to calculate the correction factor: Based on the calculations of the calorimeter correction factor, X was determined to be 0.158 g. Then using the equation q=m(HCl+X)C *T, where q is equal to the amount of energy given off, and than calculating the value in -kJ/Mol (because these are exothermic reactions) we were able to determine HA and HB. Ionic compounds are formed as the result of attraction of opposite charges. The enthalpy of formation is the energy change when one mole of a substance is formed from its constituent elements in their standard state. qA=(101.76 g + 0.158 g) x 4.184 J/gC x 21.7C, qB=(101.76 g + 0.158 g) x 4.184 J/gC x 5.50C. atoms.
