Question

2C3H7OH + 9O2 -> 6CO2 + 8H2O

How Many Moles of CO2 can be produced by reacting 6 moles of C3H7OH with oxygen?

Answer 1

Up to
`18\; \rm mol`
`\rm CO_2`.

Step-by-step explanation:

The equation for this reaction:
`2\; \rm C_3 H_7 OH + 9\; O_2 \to 6\; CO_2 + 8\; H_2O` is indeed balanced.

Notice that the coefficient of
`\rm C_3 H_7 OH` is
`2` while that of
`\rm CO_2` is
`6`.

Therefore, each unit of this reaction would consume
`2` units of
`\rm C_3H_7OH` while producing
`6` units of
`\rm CO_2`. In other words, this reaction would produce three times as much
`\rm CO_2\!` as it consumes
`\rm C_3H_7OH\!`.

If all that
`6\; \rm mol` of
`\rm C_3H_7OH` molecules are actually consumed through this reaction, three times as many
`\rm CO_2` molecules would be produced. That corresponds to
`3 * 6\; \rm mol = 18\; \rm mol` of
`\rm CO_2\!` molecules.
