The molar heat capacity of silver is 25.35 J/mol⋅∘C. How muchenergy would it take to raise the temperature of 9.10 g of silverby 10.5 ∘C? Use the following values:specific heat of water = 4.18J/(g⋅∘C) specific heat of steel = 0.452 J/(g⋅∘C)
Find ΔHrxn for the reaction: N2O(g)+NO2(g)→3NO(g) Use thesereactions with known ΔH's: 2NO(g)+O2→2NO2(g)ΔH=−113.1kJN2(g)+O2→2NO(g)ΔH=+182.6kJ 2N2O(g)→2N2(g)+O2(g)ΔH=−163.2kJ
