Which of the following types of waste should not be recycled at home?

What functional feature(s) does the phosphate group contribute to the structure of a phospholipid? select all that apply. select

bezimeni [28]

A phospholipid structure is shown in the picture attached. It has three parts: the hydrophobic tail, the hydrophilic head and the phosphate group in the center. Thus, the function of the phosphate group is to link the hydrophobic and hydrophilic parts of a phospholipid. Specifically, the phosphate group is part of the hydrophilic head. So, it is used to connect the phospholipids to polar compounds.

Why is it not possible to directly count the number of particles in a mole?

SVETLANKA909090 [29]

Answer: because a mole is based on Avogrado's number, which is 6.02 x 10²³ particles. It isn't possible to directly count that many particles at a time.

Calculate the value of [CH3OH][CO][H2]2 when all concentrations are 2.4. Keep in mind that the reaction may not be at equilibriu

NikAS [45]

Explanation:

The given reaction will be as follows.

$CO + 2H_{2} \leftrightharpoons CH_{3}OH$

So, equilibrium constant for this equation will be as follows.

$K_{c} = \frac{[CH_{3}OH]}{[CO][H_{2}]^{2}}$

As it is given that concentration of all the species is 2.4. Therefore, calculate the value of equilibrium constant as follows.

$K_{c} = \frac{[CH_{3}OH]}{[CO][H_{2}]^{2}}$

= $\frac{2.4}{2.4 \times (2.4)^{2}}$

= 0.173

Thus, we can conclude that equilibrium constant for the given reaction is 0.173.

Acetone (nail polish remover) has a density of 0.7857 g >cm3.

Stella [2.4K]

If acetone has a density of 0.7857 $\frac{g}{cm^{3} }$ the mass in grams of point A is 22.4 g and the volume at point B is 8.32 mL.

<h3>What is acetone?</h3>

Acetone is known as a chemical substance that is usually found in the environment but can also be produced artificially. Acetone is a polar organic product that interacts very well with water molecules, generating dipole-dipole relationships.It is colorless with a distinctive smell and taste, we find it in products known as <u>cleaning and personal care products</u>, but we can also use it as a solvent for substances.

Also in the environment in <u>plants, trees and in volcano emissions or in forest fires</u>, it does not become <em>toxic</em> in low doses but if it is exposed to an individual in high doses it can become <em>fatal</em>.

In the statement we can find that acetone has a density of 0.7857 $\frac{g}{cm^{3} }$ .

Therefore, we can confirm that if acetone has a density of 0.7857 $\frac{g}{cm^{3} }$ the mass in grams of point A is 22.4 g and the volume at point B is 8.32 mL.
