omg thank you! I do not understand this at all!
If 3.0 liters of oxygen gas react with excess carbon monoxide at STP, how many liters of carbon dioxide can be produced under the same conditions? 2 CO (g) + O2 (g) yields 2 CO2 (g)
that is easy!! you have to look at the equation and see how many mol of O2 and moles of CO2 you have one mol of ANY gas at STP condition has the same volume. so if you have 1mol of O2 that produce 1mol of CO2 you will have the same volume of CO2 produced than the O2 consumed in the reaction. now if in the reaction you have 1mol O2 that produce 5 mol of CO2 then the volume of the CO2 is going to be 5 times more than the volume of the O2 consumed in the reaction
im still a little confused..
tell me how many mol of O2 you see in the equation?
I see 2
NO! O2 the 2 is the sub-index that indicate how many atoms per molecule you have to look at the prefix, if there is no number before the O2 means that is 1. 2 O2 = 2 mol O2
now how many mol of O2 do you see in the equation and how many mol of CO2 do you see in the equation
1 O2 and 2 CO2
Now the amount of moles from O2 to CO2 increase by 2 then the volume will increase also by 2
3.0 L O2 x 2 mol CO2/ 1 mol O2 = 6 L CO2
do you have more?
Thank you so much!!
How many liters of methane gas (CH4) need to be combusted to produce 8.5 liters of water vapor, if all measurements are taken at the same temperature and pressure? Show all of the work used to solve this problem. CH4 (g) + 2 O2 (g) yields CO2 (g) + 2 H2O (g)
what do you think? how many mol of CH4 you have in the equation and how many moles of H2O you have in the equation?
