How many grams of MnO, are needed to prepare 10.0 liters of Cl2, gas at 22 C and 710 torr according to the following reaction? MnO2 + 4NaCl + 2H2SO4 2Cl2 + MnSO4 + Na2SO4 + 2H2O

Calculate the enthalpy of the following reaction: 4 b (s) + 3 o2 (g) → 2 b2o3 (s) given the following pertinent information: (a) b2o3 (s) + 3 h2o (g) → 3 o2 (g) + b2h6 (g), δhoa = +2035 kj (b) 2 b (s) + 3 h2 (g) → b2h6 (g), δhob = +36 kj (c) h2 (g) + latex: \frac{1}{2} 1 2 o2 (g) → h2o (l), δhoc = −285 kj (d) h2o (l) → h2o (g), δhod = +44 kj
