The balanced chemical reaction is:
HC2H3O2<span> (aq) +Ba(OH)2 (aq) --> H2O (l) +Ba(C2H3O2)2
</span>
We are given the amount of HC2H3O2 to be used in the reaction. We use this amount as the starting point of our calculations.
0.432 mol HC2H3O2 ( 1 mol Ba(OH)2 / 1 mol HC2H3O2 ) = 0.432 mol Ba(OH)2 needed
Hope this answers the question.
Answer:
#1
The temperature that this happens is called the freezing point and is the same temperature as the melting point. As more energy is put into the system, the water heats up, the molecules begin moving faster and faster until there is finally enough energy in the system to totally overcome the attractive forces.
Explanation:
#2
Heating a liquid increases the speed of the molecules. An increase in the speed of the molecules competes with the attraction between molecules and causes molecules to move a little further apart. ... A decrease in the speed of the molecules allows the attractions between molecules to bring them a little closer together.
A 3.1 L sample of hydrogen <u>d. contains the same number of molecules</u>
as 3.1 L of carbon dioxide at the same temperature and pressure.
This is the fundamental principle of <em>Avogadro’s hypothesis</em>: equal volume of gases at the same temperature and pressure contain the same number of molecules.
The sample of carbon dioxide has a <em>greater mass</em>, a <em>greater number of atoms</em>, and a <em>greater density</em>, than the sample of hydrogen.
Even if two samples of matter have the same temperature, it does not necessarily mean they have the same total energy. The more particles a substance has at a given temperature, the more thermal energy it has.
