C7H16 plus 11O2 gives 7CO2 plus 8H2O - According to this equation how many moles of carbon dioxide will be produced if 5 moles of heptane are burned?

Answer 1

Well you can see from your equation that each mole of heptane produces 7 moles of Carbon dioxide when burned so 5 moles of heptane produces 5 X 7 moles of carbon dioxide. I'll let you do the maths.

Answer 2

Reaction: 1 mole propane : 3 mole CO2

so with 3 mole propane you'll get 3 times more: thus 3x3= 9 moles CO2

Answer 3

The reaction isȘ
C7H16 + 11 O2 = 7 CO2 + 8 H2O
and the answer is 21 moles carbon dioxide.

Answer 4

If 5 moles of C7H16 are burned according to the equation, 7 moles of CO2 will be produced. This is because the stoichiometry of the balanced equation shows a 1:7 ratio between C7H16 and CO2.
