Answer to Question #293000 in General Chemistry for Amy

Question

Calculate the standard heat of vaporization for tin( IV)chloride, SnCl4.

change heat of fusion=-511.3kj/mol for SnCl4(l) and -471.5 kj for SnCl4 (g).

Answer 1

Equation 1: Sn_(s)+2Cl_2(s)→SnCl_{4(l). ∆H°=-511.3 KJ/mol.....}

Equation 2: Sn_(s)+2Cl_2(g)→SnCl_{4(l). ∆H=-471.5 KJ/mol....}

_{Equation 2- equation 1}

SnCl_4(l)-SnCl_4(g)

∆H=-471.5-(-511.3)

Ans=+39.8 KJ/mol
