A solution is a homogenous mixture of solute and solvent. There are different types of solutions. A carbonated drink is an examp

le of a solution where the solute is a gas and the solvent is a liquid. Sugar crystals dissolved in water is an example of a solution where the solute is a solid and the solvent is liquid. Acetic acid is miscible in water, forming a solution commonly known as vinegar. In this case, both the solute and the solvent are liquids. The solubility of solute in a solvent depends on various parameters, such as temperature, pressure, the nature of the solute, and the nature of the solvent. Considering these parameters, identify the statements that are correct for the solubility of a solute in a solvent.

Answer:

  • A.) Gases are readily soluble in water at higher temperatures: FALSE
  • B.) Carbon dioxide gas will be less soluble in water when the partial pressure is low: TRUE
  • C.) Zinc sulfate is soluble in water: TRUE
  • D.) Propanol and heptane are miscible: FALSE
  • E.) Table salt dissolves in water to form a solution: TRUE

Explanation:

The answer choices are:

  • A.) Gases are readily soluble in water at higher temperatures.
  • B.) Carbon dioxide gas will be less soluble in water when the partial pressure is low.
  • C.) Zinc sulfate is soluble in water.
  • D.) Propanol and heptane are miscible.
  • E.) Table salt dissolves in water to form a solution.

<h2>Solution</h2>

Let's see every statement

<u><em>A.) Gases are readily soluble in water at higher temperatures.</em></u>

This is false. At higher temperature, the gas molecules will have higher kinetic energy, meaning that they will move faster and escape more easily from the liquid phase. Thus, gases are less soluble at higher temperatures.

<u><em>B.) Carbon dioxide gas will be less soluble in water when the partial pressure is low.</em></u>

This is TRUE.

HIgher pressures "push" the gas molecules into the liquid phase. When more molecules get dissolved the pressure is partially relieved.

This relation is stated by Henry's Law: the solubility of gases in liquids is directly proportional to the pressure of the gases above the surface of the solution. Thus, carbon dioxide will me less soluble in water when the pressure is low.

<u><em>C.) Zinc sulfate is soluble in water.</em></u>

This is TRUE.

You must resort to the rules of solubility or search the properties of this salt.

Th solubility rules state that most sulfates are soluble in water. Exceptions are sulfates of Ag⁺,Ca²⁺, Sr²⁺, Ba²⁺, Hg²⁺, and Pb²⁺. Thus, you can expect that zinc sulfate is soluble in water.

<u><em>D.) Propanol and heptane are miscible.</em></u>

This is false.

Propanol is a polar compound. It is miscible with water because water is polar too. Heptane is not polar. Thus, following the rule that "like dissolves like" propanol and heptane are not miscible.

<u><em></em></u>

<u><em>E.) Table salt dissolves in water to form a solution.</em></u>

This is TRUE.

This is a classical example of an ionic compound (sodium chloride) that is soluble in water (a polar solvent), showing the rule that polar solvents dissolve polar and ionic compounds.

It is also an everyday fact: rice, for instance, absorbs salt from water because the salt is dissolved in the water.

Which shows the correct order of increasing trophic level, from producer to tertiary consumer?
polet [3.4K]

Answer:

Grass, deer, wolf, fungi.

Explanation:

The tropical level of an organism is defined as the position of organism occupied in the food chain. The food chain is starts from tropical level one which is primary producers (such as plants), then move to herbivores (such as deer) in level two, carnivores, (such as wolf) at level three, apex predators in level four (such as lions), and it ends in decomposers such as fungi.

Fungi play important role in ecosystem to help in breakdown of dead organic matter and return nutrients to the soil. Without fungi nutrients cannot cycle in an ecosystem, and causing the breakdown of entire food web.

Identify the mixture of powdered charcoal and powdered sugar and suggest a technique for separating their components
mihalych1998 [28]
A- Identify the mixture:
The mixture of powdered charcoal and powdered sugar is considered as a homogeneous mixture. This means that you cannot identify the components with naked eye as they are uniformly distributed in the mixture.

B- Separate components:
You ca separate the charcoal powder from the sugar powder using the following steps:
1- add water. Sugar will dissolve in water while charcoal won't.
2- filter the solution where the powdered charcoal will remain on the filter paper and the solution of powder will pass through.
3- boil the sugar solution (above 100 degrees celcius). The water will evaporate and the sugar will precipitate.

What size pipette accurately measures 0.8 ml of fluid? indicate the volume and accuracy of the pipette.
chubhunter [2.5K]

The pipette that accurately measures 0.8mL of fluid is P1000 micropipette.

It is given that:-

The volume of fluid = 0.8mL

We know that,

1 mL = 1000 microliter.

Hence,

0.8 mL = 0.8*1000 microliter = 800 microliter

We know that, a P1000 micropipette's volume ranges between 200 microliter to 1000 micro liter.

As,

200 < 800 < 100

Hence, P1000 micropipette is the right instrument.

The accuracy of this pipette decreases as volume decreases. Since the value 800 is near the maximum volume 1000 of the pipette, the accuracy of the pipette will be within a few percentages of the actual value.
