1. What is the volume of 4.50 moles of propane gas (C3H8 ) at STP?
2. How many moles of oxygen gas are there in 13.5 L of
oxygen gas at STP?
3. What volume (in L) will be occupied by 0.0035 moles of
chlorine gas at STP?

thanks so much

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
