Two of the simplest compounds containing just carbon and hydrogen are methane and ethane. methane contains 0.3357 g of hydrogen for every 1.00 g of carbon. the ratio of grams of hydrogen per gram of carbon in methane to grams of hydrogen per gram of carbon in ethane is 4: 3. determine the number of grams of hydrogen per gram of carbon in ethane.

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
