Consider the temperature versus time graph below. A graph of temperature versus time has time on the horizontal axis and tempera

ture in degrees Celsius from negative 20 to 140 on the vertical axis. A line extends through the following points: 0, negative 10; 4, 0; 7, 140; 18, 120; 19, 125. At what temperature is the substance a heated gas? at 100°C below 0°C above 100°C between 0°C and 100°C

Lily is doing a science experiment with a substance in a sealed jar. At first, the substance's molecules are moving around each
Alex

The molecules will be more separated, and will have least amount of intermolecular force of attraction.

<h3><u>Explanation:</u></h3>

The molecules inside the jar of Lilly are moving around each other. This means the state of the matter present inside the jar is liquid. As Lily gives more energy inside the jar , the molecules inside the jar will get more separated as the kinetic energy of the molecules increase and the intermolecular force of attraction decreases as well as the intermolecular separation or distance increase. As the energy is continued to be supplied from outside, there will be a time when this liquid will reaches boiling point and will start to change into gas. After this point the intermolecular force of attraction will be least among molecules and their separation will be maximum.

Which mixture would be best to use as a wash for removal of the alkylcatechol from skin exposed to poison ivy?water and baking s
Rudiy27

The question is incomplete. Here is hte complete question.

The components of poison ivy and poison oak that produce the characteristic itchy rash are cathecols substituted with long-chain alkyl groups. The image is attached.

If you were exposed to poison ivy, which of the treatments below would you apply to the affected area? Justify your choice.

(a) Wash the area with cold water.

(b) Wash the area with dilute vinegar or lemon juice.

(c) Wash the area with sopa and water.

(d) Wash the area with soap, water and baking soda (sodium bicarbonate)

Answer: (d) Wash the area with soap, water and baking soda.

Explanation: Alkyl is hydrophobic, which means it doesn't "mix" with water. To make it more soluble in water, soap helps to dissolve the chemical compound. As shown in the image, alkylcathecol is mildly alkaline. Baking soda is a salt that also helps dissolve it by ionizing with the -OH group, which makes it more soluble.

Although lemon juice and vinegar are acids, they are weak acids and so, won't have a strong effect on the alkylcathecol.

As said before, alkyl is hydrophobic, so plain water won't affect in any way the cathecol.

Which statement is correct abound chemical bonding in BF3 molecule O The molecule is not stable and hardly exist since the numbe
IceJOKER [234]

The molecule is stable and can exist even though the number of valence electrons around central atom in the molecule are less than 8.

<h3>Is BF3 molecule stable or not?</h3>

BF3 molecule is a stable molecule because all the electrons present in the outermost shell of boron are covalently bonded with fluorine. Boron in BF3, three bonds is the maximum possible because boron only has 3 electrons to share.

So we can conclude that the molecule is stable and can exist even though the number of valence electrons around central atom in the molecule are less than 8.
