Gaseous ethane (CH3CH3) reacts with gaseous oxygen gas (O2) to produce gaseous csrbon dioxide (CO2) and gaseous water (H2O). If 8.99g of carbon dioxide is produced from the reaction of 9.62g of ethane and 13.3g of oxygen gass, calculate the percent yeild of carbon dioxide.

Which is not true regarding reaction rates? (2 points) catalysts are not used up in the reaction. catalysts speed up reactions by lowering the activation energy. reaction rates decrease as the concentration of reactants decrease. during reactions, concentrations of all reactants decrease at the same rate.
