If 22.5L of nitrogen at 0.98 atm is compressed to 0.95 atm,what is the new volume?
Ksenya-84 [330]

At constant temperature, if the pressure is compressed to the given value, the volume of the nitrogen gas increases to 23.2L.

<h3>What is Boyle's law?</h3>

Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.

Boyle's law is expressed as;

P₁V₁ = P₂V₂

Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.

Given that;

  • Initial volume of the gas V₁ = 22.5L
  • Initial pressure of the gas P₁ = 0.98atm
  • Final pressure of the gas P₂ = 0.95atm
  • Final volume of the gas V₂ = ?

P₁V₁ = P₂V₂

V₂ = P₁V₁ / P₂

V₂ = (0.98atm × 22.5L) / 0.95atm

V₂ = 22.05Latm / 0.95atm

V₂ = 23.2L

Therefore, at constant temperature, if the pressure is compressed to the given value, the volume of the nitrogen gas increases to 23.2L.

EXTRACTION OF CAFFEINE 1.Explain the reason each step of the separation is performed with three portions of the solvent rather t
marissa [1.9K]

Answer:

Throughout the explanations section below you will find a description of the question.

Explanation:

(1)

  • Whether a solution would be positioned inside a separative funnel, combined water, as well as solvent, disintegrate particulate caffeine. In every stage, the caffeine content incorporated relies upon the coefficient of caffeine partitioning throughout the combination of water as well as fluid.
  • Thus, increasingly caffeine is taken from the solvent whenever the moment you bring additional solvent. Consequently, we separate the solvent from the single component.

(2)

  • For compounds to be mixed thoroughly and separated into different layers, a shuddering mixture within the dividing funnel would be essential.
  • However, it vibrates the separation funnel forcefully, restricts airflow within the funnel, which can also induce the fluid under it to burst or causing fluid to fire.

What is most likely the ph of a solution containing many hydroxide ions (oh-) and few hydrogen ions (h )?
SIZIF [17.4K]
PH of solution will be greater than seven (pH>7), that means that solution is basic (<span>pH above </span>7<span> is a base, the higher the number, the stronger is the base).
</span>pH (potential of hydrogenis) is a measure of the hydrogen ion (H⁺) concentration of a solution. <span>Solutions with a pH less than 7 are acidic.</span>

Calculate the molarity of a solution that contains 0.175 mol of zncl2 n exactly 150 ml of solution.
scoray [572]
Molarity = mol/L

0.175 mol
0.15 L (1000 mL = 1 L)

Molarity = 0.175 mol/0.15 L = 1.1666667 M
