Which of the following is a valid mole ratio from the balanced equation 2c3h6 + 9o2 → 6co2 + 6h2o? 1 mole of c3 h6/ 2 moles of c o2 6 moles of h2 o/ 9 moles of o2 2moles of c3 h6/ 6 moles of o2 3 moles of h2 o/ 2 moles of c o2

                  6 moles of H₂O / 9 moles of O₂

The Balance Chemical Equation is as follow,

                                    2 C₃H₆ +  9 O₂     →   6 CO₂  + 6 H₂O

According to this balance equation 2 moles of C₃H₆ (Propene) when combusted with 9 moles of O₂ (Oxygen) produces 6 moles of CO₂ (Carbon Dioxide) and 6 moles of H₂O (Water Vapors).

Hence, Given options are;

1 mole of C₃H₆ / 2 moles of CO₂: This is incorrect because 1 mole of C₃H₆ will produce 2 moles of CO₂.

6 moles of H₂O / 9 moles of O₂: This is correct as 6 moles of H₂O is produced by reacting 9 moles of O₂.

2 moles of C₃H₆ / 6 moles of O₂: This ratio is incorrect because for complete oxidation 2 moles of C₃H₆ requires 9 moles of O₂.

3 moles of H₂O / 2 moles of CO₂: This is also incorrect because the production of 3 moles of H₂O will be accompanied by the production of 3 moles of CO₂.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
