In which of the following processes is the end product more ordered than the reactants? (in which process does entropy decrease.) select one: a. a. 2h2 (gas) + o2 (gas) = 2 h2o (gas) b. b. 2c8h18 (liquid) + 25o2 (gas) = 16co2 (gas) + 18h2o(gas) c. c. c6h12o6 (solid) + 6o2 (gas) = 6co2 (gas) + 6h2o (liquid) d. d. 2c7h5n3o6 (solid) = 3n2(gas) + 7co(gas) + 5h2o(gas) + 7 c(solid) e. e. nahco3(solid) + c2h4o2(liquid)=c2h3nao2(solid)+ h2o(liquid) + co2(gas)
