Answer 1

2C6H14 + 19O2 → 12CO2 + 14H2O

The theoretical number of carbon dioxide moles produced from three moles C6H14 is

2 moles of C6H14 gives 12 CO2

If 3 moles of C6H14 gives ??

(3 x 12)/ 2 = 18 Answer is B. 18

2C3H8O + 9O2 → 6CO2 + 8H2O

The maximum number of moles of carbon dioxide that can be isolated from four moles of C3H8O is ___

2 moles of C3H8O gives 6 CO2

4 moles of C3H8O gives ??

(4 x 6)/ 2 = 24/2 = 12 Answer is A.12

2C6H14 + 19O2 → 12CO2 + 14H2O

If 3 mol of C6H14 and 25 mol of O2 are reacted, the limiting reactant is

Answer is
