It could get bigger or it could have something a lot different to it than anything else
Both derive from H20, one is agitated molecules from being heated up. The other molecules are slowed down by being cooled.
Molar mass Cu(OH)2 => 97.561 g/mol
Therefore:
1 mole Cu(OH)2 ------------ 97.561 g
? moles Cu(OH)2 ----------- 68 g
= 68 x 1 / 97.561
= 68 / 97.561
= 0.696 moles of Cu(OH)2
Answer:
gravitational potential energy
Explanation:
a. You can rule out kinetic energy because it is a different type (the energy of motion).
<u>b. this is correct, because it is the energy that depends on an objects place on the gravitational field. As you can imagine, an object resting at a high place could be moved by gravity if it has the chance to fall.</u>
c. I am assuming you meant elastic, and that can be ruled out because while that is potential energy, it is dependent upon being stretched (for example a rubber band holds elastic energy when stretched).
d. mechanical energy is the sum of both kinetic and potential energy, and the question specifically asks about potential energy.
