The balanced equation below represents a reaction between propane and oxygen. C3H8 + 5 O2 → 3 CO2 + 4 H2O According to this equation, which ratio of propane to oxygen is correct? 5 grams CO2 1 gram C3H8 3 moles CO2 1 mole C3H8 5 moles O2 1 mole C3H8 3 moles CO2 4 moles H2O

5 moles O2 1 mole C3H8

Explanation:

In the question, it is mentioned about the ratio Propane and Oxygen. So the the ration will be 1:5 i.e, 5 moles of O2 1 mole C3H8. There is only one option which mentions both Propane and Oxygen and others doesn't.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
