Match the mixture with the substance// I really need help on this guys (it’s a pic btw)
koban [17]

Answer:

See below  

Step-by-step explanation:

1. Colloid

B) Microscopic insoluble particles that are suspended throughout another substance.

Milk is a colloid. It consists of small fat globules suspended in water.

2. Emulsion

D) Two or more liquids that are not normally mixable.

Mayonnaise is an emulsion. It consists of oil, egg yolks, vinegar, and seasonings. Normally, the oil and vinegar (95 % water) do not mix. Without the egg yolk , they would quickly separate. Egg yolk contains the emulsifier, lecithin, which is attracted to both oil and water and stabilizes he mixture.

3. Solution

A) A solute that is evenly distributed within the solvent.

Sugar syrup is a solution of sugar in water.

4)Homogeneous

C) A mixture that has its components distributed evenly within the substance.

A homogeneous mixture has only one phase. For example, the sugar syrup is homogeneous, because, even with a powerful microscope, you can't see a boundary between the sugar particles and the water.

In a plant, 1500kg of nitrogen oxide is consumed per day to produce 1,500 kg of nitrogen per day. What is the prevent yield?
slavikrds [6]

Answer:

65.21 percent

Explanation:

We are to find the percentage yield

We have this equation,

2no+o2 -->2no2

Such that 1500 kilograms/30grams

= Mno2/46

=1500/30 = mno2/46

We cross multiply from here

1500x46 = 30xMnO2

69000 = 30Mno2

69000/30 = MnO2

2300 = Mno2

The percentage yield would be

1500/2300 *100

= 0.6521 x 100

= 65.21%

This answers the question

As the amount of a substance increases what does the density of the substance do
hram777 [196]

Answer:

As the amount of substances increases density will increase.

Explanation:

Density and mass have direct relation while density and volume has inverse relation. If the volume of substance is kept constant then the density of substance will increase with same factor as the mass of substance is increases.

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Dalton's law states that Dalton's law states that a. the volume of gas that will dissolve in a solvent is proportional to the so
irina [24]

Answer:

c. in a mixture of gases like air, the total pressure is the sum of the individual partial pressures of the gases in the mixture.

Explanation:

<em>Dalton law is also known as Dalton's law of partial pressure. It simply explains that the total pressure exerted by a mixture of gases in a container is the sum of the individual gas pressure (partial pressure) exerted by each of the gases.</em>

Hence, the correct option is C.
