Consider the combustion reaction for acetylene: 2C2H2(l) + 5O2(g) → 4CO2(g) + 2H2O(g). If the acetylene tank contains 37.0 mol of C2H2 and the oxygen tank contains 81.0 mol of O2, what is the limiting reactant for this reaction?
Added by Marc F.
Step 1
Determine the stoichiometric ratio of C2H2 and O2 in the reaction: From the balanced equation, we see that 2 moles of C2H2 react with 5 moles of O2 to produce 4 moles of CO2 and 2 moles of H2O. Therefore, the stoichiometric ratio of C2H2 to O2 is 2:5. Show more…

When acetylene gas, C2H2, burns according to the balanced equation below, how many liters of C2H2 at 25.0 °C and 4.50 atm are combusted for every 3.78 mol of oxygen consumed? 2C2H2 (g) + 5O2 (g) --> 4CO2 (g) + 2H2O (g)
Acetylene (C2H2) gas and oxygen (O2) gas react to form carbon dioxide (CO2) gas and water (H2O) vapor. Suppose you have 3.0 mol of C2H2 and 2.0 mol of O2 in a reactor. What would be the limiting reactant? Enter its chemical formula below.
