The statement that best describes the type of bond a molecule of water has and how the electrons behave is : O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it; option D

<h3>What are covalent molecules</h3>

Covalent molecules are molecules which are formed by the sharing of electrons between atoms of two or more elements whose elecyronegativity values are close to each other.

Covalent bonds are usually formed by non-metals such as hydrogen, oxygen, nitrogen to form their gases.

Example of covalent molecules include water and hydrogen gas.

<h3>What are Polar molecules</h3>

Polar molecules are molecules which are formed by the uneven sharing of electrons between atoms or by the formation of ions by substances such that the two ends of the molecule will have different charges, positive and negative.

In polar covalent molecules, the more electronegatibe element pulls the shared electrons more to itself. For example, in a water molecule which is polar, oxygen pulls the shared electrons with hydrogen more to itself to have a partial negative charge while the hydrogen atom has a partial positive charge.

Therefore, statement that best describes the type of bond a molecule of water has and how the electrons behave is : O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it; option D

Answer:

see below

Explanation:

1. One atom pulls an electron from another atom.

2. Forming bonds releases energy and is exothermic.

3. Additional bonds require more energy to break, so the bond energy is higher.

4. −153

5. O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it.

Question 1: A substance that is soluble in two liquids and makes an emulsion last longer is called what?
Pavlova-9 [17]

<u>Answer:</u>

1. A substance that is soluble in two liquids and makes an emulsion last longer is called "Emulsifier".

2. The process that reduces the size of particles so emulsions will last longer is called "Homogenization".

<u>Explanation:</u>

Emulsifiers are additives which enable two liquids to mix around each other. Water and oil separate in a container, for an instance, but using an emulsifier can make the liquids blend along. It is widely used on various foods and beverages. Egg yolks and mustard are a few examples of emulsifiers.

Homogenization is the physical mechanism by which the fat molecules in milk are broken down because then they stay incorporated instead of segregated as cream. Majority of the milk sold in the United States is homogenized.

When 20 grams of KCIO3, is dissolved in 100 grams of water, the solution can be
tia_tia [17]

Answer:

b. unsaturated .

Explanation:

Hello there!

In this case, according to the given information, it turns out necessary for us to bear to mind the definition of each type of solution:

- Supersaturated solution: comprises a large amount of solute at a temperature at which it will be able to crystalize upon standing.

- Unsaturated solution: is a solution in which a solvent is able to dissolve any more solute at a given temperature.

- Saturated solution can be defined as a solution in which a solvent is not capable of dissolving any more solute at a given temperature.

In such a way, since 20 grams of the solute are less than the solubility, we infer this is b. unsaturated, as 33.3 grams of solute can be further added to the 100 grams of water.

Regards!

Which of the following natural resources cant be reused
ohaa [14]
Hi there! Air and sunlight can definitely be reused. Those are abundant and renewable resources. Therefore, A and D are eliminated. There is a limited amount of water, however, it's impossible to run out of it to the point that there's no more on Earth. C is out. The only answer choice that makes sense is coal, because it's a nonrenewable resource, and it takes millions of years to make more of. It's a fossil fuel, so once we use them up, we can't get anymore during our lives. The answer is B: coal.
