Hydrogen bonds can be found between molecules of which of the following

Chemistry
1 answer:
Fantom [35]2 years ago
8 0

Answer:

HF

Explanation:

Hydrogen bond is one of the chemical bonds that holds atoms and molecules together. Hydrogen bonding forms between an hydrogen atom and an electronegative atom such as fluorine, oxygen, or nitrogen. These electronegative atoms pull most of the electrons from the hydrogen atom, thereby, making the molecule a polar one.

An example of molecules that forms hydrogen bonding is Hydrogen fluoride (HF). The hydrogen atom of one HF molecule is attracted to the very electronegative fluorine atom of another HF molecule due to the difference in electrons. This forms the HYDROGEN BOND in HF molecule.

Toxicants generally follow the laws of ________, moving from areas of high concentration to areas of lower concentration
zloy xaker [14]

Toxicants generally follow the Law of Diffusion , moving from areas of high concentration to areas of lower concentration.

<h3><u>What are Toxicants ?</u></h3>

Any hazardous chemical is a toxicant. Both naturally occurring and artificial toxicants have the potential to be harmful. A toxin, in contrast, is a poison created spontaneously by an organism (e.g. plant, animal, insect). The many toxicant categories may be present in the air, land, water, or food.

A substance is toxic if it has the potential to be harmful or have negative effects on health. Chemicals like polychlorinated biphenyls (PCBs) and dioxin, which are present at some hazardous waste sites, often cause people to worry.

<h3><u>What is the Law of Diffusion ?</u></h3>

Graham's law of diffusion states that the ratio of the diffusion rate of two gases is the same as the ratio of the square root of the molar mass of the gases.

Describe one way to prove that a mixture of sugar and water is a solution and that a mixture of sand and water is not a solution
Llana [10]

Answer:

The solution is always homogeneous mixture and transparent through which the light can travel. The mixture of water and sugar is a solution because sugar is soluble in water and form homogeneous mixture while the sand can not dissolve in water and sand particles scatter the light.

Explanation:

Solution:

"The solution is always homogeneous mixture and transparent through which the light can travel"

The mixture of water and sugar is a solution because sugar is soluble in water and form homogeneous mixture. The solubility of sugar is high as compared to the sand in water because the negative and positive ends of sucrose easily dissolve into the polar solvent i.e, water

Suspension:

"Suspension is the heterogeneous mixture, in which the solute particles settle down but does not dissolve"

The mixture of water and sand is suspension. The sand can not dissolve in water because it is mostly consist of quartz. The nonpolar covalent bonds of  sand are too strong and cannot be break by water molecules.
