What are the products of simple decomposition?

In numbering carbon atoms in the parent chain of a hydrocarbon, why would you number from right to left, rather than left to right

When an object falls through the air and encounters air resistance its overall speed will be than if it had not encountered air resistance? (one word answer)

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
