One essential step in the manufacture of many plant fertilizers is the production of nitrogen monoxide gas, NO(g). This step is represented by the following balanced equation: 4 NH3(g) + 5 O2(g) --> 4 NO(g) + 6 H2O(l) Determine the amount of oxygen needed to produce 1.2 x 104 mol of nitrogen monoxide gas.

1.5 moles, or 48 grams

Explanation:

Set up the following:

× = 1.5 moles of O2 needed

If you're also looking for the number of grams needed:

× = 48 grams needed

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.
