Please HELP Water can be separated into its elements. If 20.0 g water is decomposed by this method, how many liters of oxygen gas will be produced assuming STP? 2H2O --> 2H2 + O2

6.23 L oxygen gas

12.4 L oxygen gas

11.2 L oxygen gas

7.00 L oxygen gas

the answer is a. co2, this would be colder than the : )

explanation:

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.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
