26. For each of the following balanced equations, calculate how many grams of each product would be pro- duced by complete reaction of 15.0 g of the reactant
indicated in boldface.
a. 2BC13(s) + 3H2(3) → 2B(s) + 6HCl(3)
b. 2Cu2S(s) + 302(g) → 2Cu2O(s) + 2802(g)
c. 2Cu2O(s) + Cu2S(s) + 6Cu(s) + SO2(8)
d. CaCO3(s) + SiO2() → CaSiO3(s) + CO2(3)

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
