what word describes when tiny droplets of one liquid are finely dispersed within another liquid?

Answers

When tiny droplets of one liquid are finely dispersed within another liquid it is called emulsion.

Emulsion can be defined as the process by which two liquids that are not miscible come together to form a mixture.

The emulsion mixture usually consists of an oil phase and a water phase.

The oil phase appears as droplets when dispersed (mixed with) the water phase.

The uses of emulsion include:

It is used in chemical industries for production.

It is used for production of medicine.

Digestion of fatty food components in the intestine takes place through the process of emulsion.

The following image shows what happens when the particles in a certain state occupy a space. What is the state of the substance that is occupying the space and how do you know?





A. The substance is a gas because the particles are spreading out to fill the space of the container.


B. The substance is a liquid because the particles inside are taking the shape of the container.


C. The substance is a mixture of a gas and a liquid because the particles are filling the space of the container.


D. The substance is a solid because the particles inside the box have a definite shape.

Answers

Answer:

A

Explanation:

The substance is a gas because the particles far randomly arranged and far apart from each other. This happens because when a substance is a gas, particles have weak attraction to each but a lot more kinetic energy which means the they move around all the time spreading out to fill the container. If it was a solid, then all the particles would be very close together and have a fixed position and if it was a liquid then the particles would be fairly close and moving around each other but as we can see in the diagram, all the particles are far apart confirming that it is a gas.

The balanced chemical equation for the reaction of solid carbon with oxygen gas to form carbon monoxide gas is  2 C + O₂[tex]\rightarrow[/tex] 2 CO.

What is chemical equation?

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

What is a hydrogen atom?

Hydrogen is a chemical element placed at the top of group 1 in the periodic table and is represented by the chemical symbol H and atomic number 1.

A hydrogen atom is the lightest atom of the element in the whole periodic table. Hydrogen exists as a gas of diatomic molecules having the formula H₂ at standard conditions. Hydrogen gas is tasteless, colorless, odorless, non-toxic, and highly combustible.

Hydrogen is constituting roughly 75% of all normal matter and is the most abundant chemical substance in the universe. Most of the hydrogen element on Earth exists in forms like water and organic compounds.  Each atom of hydrogen (¹H) has one proton, one electron, and no neutrons.

Hydrogen element is nonmetallic and easily forms a single covalent bond with most nonmetallic elements, forming compounds like water.
