Using the reaction below, how many moles of co2 can be produced when 2.25 mol of c3h8 reacts?

c3h8 + 5o2 --> 3co2 + 4h2o

The answer to your question is 6.75 moles of CO₂

Explanation:

Balanced reaction

                             C₃H₈  + 5O₂    ⇒    3CO₂   +  4H₂O

Check that the equation is balanced

                         Reactant        Element              Product

                               3                    C                          3

                               8                   H                          8

                              10                  O                         10

This equation is balanced

Use proportions to find the moles of CO₂ produced.

                         1 mol of C₃H₈    3 moles of CO₂

                       2.25 moles of C₃H₈     x

                        x = (2.25 x 3) / 1

                       x = 6.75 moles of CO₂

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
