Consider the chemical equations shown here. CH (9) +20,(9) → CO2 (9)+ 2H, O(9) AH, = -802 kJ
2H2O(g) → 2H, O(1) AH, -
= -88 kJ
Which equation shows how to calculate Arxn for the equation below?
CH,(9) + 20 (0) - CO,(9)+ 2H 0(1)
-802 kJ - 88 KJY
COMPLETE
What is AHxn for the overall reaction?
KJ

PLEASE FOCUS ON THE SECOND PART !!

where's the diagram?

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.
