Iron pyrite, FeS2, reacts with O2 according to the following reaction: 4 FeS2(s) + 11 O2(g) ® 2 Fe2O3(s) + 8 SO2(g)
a) Calculate the mass of Fe2O3 that is produced from the reaction of 75.0 L of
O2(g) at 2.33 atm and 150.0oC with an excess of FeS2.

During which time interval does the object travel approximately 10 meters

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
