Question
Determine the enthalpy for the addition of Mg to HCl for this trial. Assume the specific heat capacity is 4.184 J/g degrees Celsius.
Givens:
mass of Mg = 0.150 g
moles of Mg = 0.00617 mol
mass of HCl= 45.0 g
temperature of calorimeter= 21.5 degrees celsius
max temp. of mixture = 35.6 degrees celsius
mass of calorimeter, Mg & HCl after reaction: 169.620 g
I know the formula is qrxn = m x c x change in T + C cal x change inT cal
,but I'm unsure where the values go
