Please show me how to work! thanks

When Snno2(s) is formed form the comustion of gray tin, the reaction enthalpy is -578.6 kJ, and when white tin is burned to form SnO2(s), the reaction enthalpy is -580.7 kJ. Calculate the reaction enthalpu for Sn(gray)-->Sn(white)

  • Chemistry - ,


  • Chemistry - ,

    Sngrey + O2 ==> SnO2 -578.6
    SnO2 ==> Snwhite + O2 580.7
    Add the two equations
    Sngrey ==> Snwhite
    I have turned equation 2 around and changed the sign of dHf.
