| CHEMISTRY HELP!!! Stoichiometry!!!!?
There are 3 questions. 1) C(2)H(2) burns in oxygen and forms CO(2) and H(2)O at STP. What Volume of oxygen is needed to produce 18.0 L of CO(2)? 2) How many L of hydrogen gas will be produced by the reaction of 15.0g of calcium with HCl at STP? 3) What will be the volume of SO(2) produced at 30 Degrees Celcius and 0.963 atm if 25.0g of sulfer reacts with oxygen? She gave us the answers, but I need to know how to find them. The answers are 1) 22.5 L O(2) 2) 8.38 L H(2) 3) 19.9 L Please help and explain as much as possible!      |
