    Hey could someone pls help me with this question its been bugging me for a while now and i just hate physical chemistry

    1g of calcium is reacted with excess fluorine gas in a calorimeter with a heat capacity of 1 kj K^-1 causing the temperature to rise from 25C to 28C

    calculate the enthalpy of formation at 298K

    I'm not sure if it's most effective to perform the calculations for you (unless you've already made an attempt and haven't managed to make any headway), could you tell us what you've been able to pick out from the question?

    I'll post a worked solution on the thread afterwards if you're still stuck.
