What is the relationship between the amount of space and the state of matter

1 answer:

6 0

The relationship between the amount of space between particles and the state of matter is that if the distance between the particles is very very less or closely packed) then it said to be a solid , If the distance between the particles is very less (more than that of solid) then the matter is a liquid & If the distance between the particles is less (more than that of liquid) then it is said to be gaseous. By this we conclude that when the amount of space between the particles varies then the states of matter (Solid , Liquid , Gas) also differs.

Which solution is a homogeneous mixture? sand and water salt and water salad dressing soil

Over [174]

Answer: Option (b) is the correct answer.

Explanation:

A solution whose constituent particles are uniformly distributed in the solution is known as a homogeneous solution.

In a homogeneous solution, particles of one solute completely dissolves in the solvent. This solution is also known a true solution.

When sand and water are mixed together then after a certain interval of time sand particles will settle at the bottom. Therefore, they do not dissolve in water. So, it is not a homogeneous solution.

When salt and water are mixed together then the salt particles will dissolve in water. Therefore, it is a homogeneous solution.

Salad dressing is not a homogeneous solution as it contains different solutions like oil, lemon juice etc which does not dissolve when mixed together.

On the other hand, soil is also not a homogeneous solution because we can visualize the distinct layers present in a soil. These layers when mixed in a solution does not dissolve so they did not form a homogeneous solution.

Thus, we can conclude that out of the given options, salt and water is a homogeneous mixture.

1. Freon (CCl2F2) is commonly used in refrigerators and air conditioners as a coolant. How many grams of fluorine are there in t

Georgia [21]

Answer:

285g of fluorine

Explanation:

To solve this problem we need to find the mass of Freon in grams. Then, with its molar mass we can find moles of freon and, as 1 mole of Freon, CCl₂F₂, contains 2 moles of fluorine, we can find moles of fluorine and its mass:

Mass Freon:

2.00lbs * (454g / 1lb) = 908g of Freon

Moles freon -Molar mass: 120.91g/mol- and moles of fluorine:

908g of Freon * (1mol / 120.91g) =

7.5 moles of freon * (2moles Fluorine / mole Freon): 15 moles of fluorine

Mass fluorine -Atomic mass: 19g/mol-:

15 moles F * (19g / mol) =

<h3>285g of fluorine</h3>
