Answer:

A solution can be diluted and saturated at the same time depending on the solubility of the solute.

Explanation:

A dilute solution is when the amount of solute is in a small amount of solvent, and a saturated solution occurs when the solvent contains the maximum amount of solute that can be dissolved at a specific temperature.

These 2 concepts can occur at the same time depending on the solubility of the solute, for example a saturated solution of CaCO3 will be diluted because the compound is very poorly soluble in the solvent.

Dilution is when you decrease the concentration of a solution by adding a solvent. As a result, if you want to dilute salt water, just add water. ... Add more solute until it quits dissolving. That point at which a solute quits dissolving is the point at which it's saturated.

Answer:

58.61 grams

Explanation:

Taking The molecular weight of NaCl = 58.44 grams/mole

Determine how many grams of NaCl to prepare the bath solution

first we will calculate the moles of NaCl that is contained in 6L of 170 mM of NaCI solution

= ( 6 * 170 ) / 1000

= 1020 / 1000 = 1.020 moles

determine how many grams of NaCl

= moles of NaCl * molar mass of NaCl

= 1.020 * 58.44

= 58.61 grams

The air inside a flexible 3.5L container has a pressure of 115Kpa. What should the volume of the container be increased to in th

LenaWriter [7]

Answer:

V₂ = 4.82 L

Explanation:

Given data:

Initial volume of gas = 3.5 L

Initial pressure = 115 Kpa

Final volume = ?

Final Pressure = 625 torr

Solution:

Final Pressure = 625 torr (625/760 =0.82 atm)

Initial pressure = 115 Kpa (115/101 = 1.13 atm)

The given problem will be solved through the Boly's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume

Now we will put the values in formula,

P₁V₁ = P₂V₂

1.13 atm × 3.5 L = 0.82 atm × V₂

V₂ = 3.955 atm. L/0.82 atm

V₂ = 4.82 L

Enter the appropriate symbol for an isotope of phosphorus-32 corresponding to the isotope notation AZX. Express your answer as a

Lelechka [254]

Answer:

$^{32}_{15}P$

Explanation:

Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.

However, when we talk about the atomic number of the ion, it is not equal to the number of electrons as electron can be gained or loosed.

This is why, more appropriately, the number of the protons which are present in the nucleus of the atom is called the atomic number.

Thus, atomic number of phosphorus = 15

Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.

Given, Mass number = 32

Thus, the symbol of the isotope is:-

$^{32}_{15}P$

Your little sister asks you a scientific question: "Does chocolate milk come from brown cows?" In order to answer the question,

aksik [14]

Answer:

Hey there,

Your answer is iii. Brown cows produce white milk. (1 point) and ii. Brown cows never produce chocolate milk. (1 point)

You already know from the basic understanding that chocolate comes from beans, not cows, and is added to milk, and thereby- brown cows do not produce chocolate milk. You also know that they produce white milk.
