Regarding the vaporization of water, which of the following is true? A. A great deal of heat must be lost by water to form hydrogen bonds and allow molecules to move farther apart. B. A great deal of heat must be absorbed by water to break hydrogen bonds and allow molecules to move farther apart. C. Vaporization of water is an exothermic process. D. Water must lose a great deal of heat before it will vaporize.

Answers

Answer 1

Answer:

Answer: B. A great deal of heat must be absorbed by water to break hydrogen bonds and allow molecules to move farther apart.

Explanation:

Vaporization is a physical process where liquid state changes to gaseous state.

$H_2O(l)\rightarrow H_2O(g)$

Water molecules are bonded by strong hydrogen bonding between the hydrogen atom and the electronegative oxygen atom. Thus water molecules present on the surface are strongly attracted by the molecules present below the surface.

Thus as liquid state has to be changed to gaseous state, the heat must be supplied and the reaction will be endothermic.The heat is used to break the inter molecular forces or the hydrogen bonds present in water to convert them to randomly moving gaseous state.

Answer 2

Answer: B. A great deal of heat must be absorbed by water to break hydrogen bonds and allow molecules to move farther apart.

How do you get all the amino acids that your body needs to make proteins?

Answers

In order to get all the amino acids that the body needs to produce proteins, one must eat and drink the necessary food containing amino acids. Amino acids are what comprises proteins thus, in order to obtain the average amount of amino acid, make sure that you have an enough intake of foods rich in proteins.

Catalysts affect the chemical reactions that take place within the body. What function do catalysts perform in chemical reactions?a. Catalysts slow down the rate of chemical reactions.
b. Catalysts are always formed by chemical reactions.
c. Catalysts are used up during a chemical reaction.
d. Catalysts lower the activation energy of a chemical reaction

Answers

I think the best answer for this is D. Catalysts lower the activation energy of a chemical reaction. Catalyst is a substance that speeds a chemical reaction. It is not consumed as the reaction proceeds. A catalyst offers a new route for faster reaction.

According to the electron-cloud model of the atom, an orbital is a(1) circular path traveled by an electron around the nucleus
(2) spiral path traveled by an electron toward the nucleus
(3) region of the most probable proton location
(4) region of the most probable electron location

Answers

Answer : Option 4) Region of the most probable electron location.

Explanation : As per the electron cloud model of the atom, an orbital is a region where the probability of finding an electron is highest. According to this model which was used to identify the probable location of the electrons when they go around the nucleus of an atom.

This electron cloud model was different from the older Bohr atomic model by Niels Bohr.

According to the electron-cloud model of the atom, an orbital is a "region of the most probable electron location" In this mode, an electron can actually be in two places at once.

Could it have something to deal with the teeth or mouths? The first pumpkin you have two teeth, second pumpkin looks like a 0, the third pumpkin I’m unsure of. The forth pumpkin has two teeth again same with the fifth.

So first pumpkin - 2
The second pumpkin - 0
The third pumpkin I’m unsure of
The forth pumpkin - 2
The fifth pumpkin - 2
So 20?22
