You have to calculate Delta Hrxn (in kJ) for: B2H6(g) + 6C12(g) -> 2BC13(g) + 6HCl(g) -> Given: 1. BC13(g) + 3 H2O(1) -> H3BO3(s) + 3 HCl (g) (Delta Hrxn=-112.5kJ) 2. B2H6(g) + 6 H2O(1) -> 2 H3BO3(s) + 6 H2 (g) (Delta Hrxn=- 493.5kJ) 3. 1/2 H2 (g) + 1/2 Cl2(g) -> HCl(g) (Delta Hrxn--92.3kJ) What combination of reaction equations is red? Check all that apply -2 x equation 1 12 x equation 3 1 x equation 2 2 x equation 2 -6 x equation 3 - 1 x equation 1
