In the reaction hcl (aq) + naoh (aq) → nacl (aq) + h2o (l), if 45.0 milliliters of a 2.0 m hcl react in an excess of naoh, how many grams of h2o will be produced?

0.045 L × 2.0 M = 0.09 mol

0.09 mol × 1 mol H2O/1 mol HCl = 0.09 mol H2O

0.09 mol H2O × 18 g/1 mol = 1.62 g

Solution: 1.62 grams of H2O

Answer from edmentum

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.

the objects have the same charge is correct.
