Enthalpy Changes Practical As Level Chemistry

[@MtechxLK]

Thank you so much, I was finding the method and also for reading to try out a practical paper based on enthalpy changes.

[@Krn_K]

I am begging you... Can you please tell me what's the enthalpy change of the displacement reaction between Magnesium and Copper sulafte? I've been looking for hours for the exact value ... and I cannot find it. Where to look?

[@rifannizar8629]

sir i have a doubt
in the equation Q=mc(temp change)
is m only the mass of water and liquids that have same density as water
or the substances added like for example I have a solution of 20cm^3 and I add 4g of FB5( salt Na2A.5H2O)
then do I add the mass of FB5 also to get Q=(20+4)*4.18*(temp change)
or would I just do Q=20*4.18*(temp change)
please answers I have my p3 exam tomorrow

1g= 1cm^3 that's the assumption here. so m is the volume of the liquid used.
