I placed some magnesium ribbon in HCl and measured the temperature change. How would i find the change in enthalpy per mole of magnesium in the following reaction:
Mg + 2HCl --> H2 +MgCl2
If i know the following information: change in temperature = 19C
mass of ribbon = 0.5g
volume of HCl = 100mL
I can't use any known values (i.e. like the ones you'd find in a textbook). I must use the experimental values above. However, i can use specific heat capacity values, c, if i must.
