Can someone help me out with this one?
I have 105cm^3(2*100+10)/2)
So you know that equal volume of gases have equal volume at the same temperature and pressure.
It means 2V of X combines with 1 V of Y to give 2V of Z
One of the gases is the limiting reactant .Find out the limiting reactant and calculate volume of Z formed from limiting reactant and volume of gas left as excess reagent.
1V of Y combines with 2V of X
so.... 10mL of Y will combine with how much volume of X?
10mL of Y will give how much volume of Z?
How much volume of X left unreacted ?
