Oxygen reacts with 22g of C5H10 producing CO2 and water. What will the volume of CO2 produced at STP?

The numbers in the equation are subscripts *in front of compound are coefficients to balance the equation please show your work, so i can see how you did it(:

CH4(g)+2O2(g)=CO2(g)+2H2O(g)

Chemistry

3Al(a) + 3NH4ClO4(s) = Al2O3(s) + AlCl3(s) + 3NO(g) + 6H2O (g)

CH4(g)+2O2(g)=CO2(g) +2H2O(g)

SiCk4(g) +2Mg(a) =2MgCl2(aq) +Si(s)

how many moles of oxygen are formed? a. 0.36 b. 0.54 c. 1.06 d. 2.50
