C3H8+ 5 O2-->3 CO2+ 4 H2O How many moles of Oxygen are necessary to produce 3 moles of CO2?

If you wanted to produce 9moles of CO2, how many moles of C3H8 would you need?

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
