The following molecular scenes depict an important reaction in nitrogen chemistry (nitrogen is blue; oxygen is red): Write a balanced equation for this reaction. N2O5 ___NO2 + ___O2

2 N2O5 4 NO2 + 1 O2

Explanation:

For the last one you dont really have to add the 1 but you can if its nedded,

since 3 divided by 3 is 1.

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.
