The gas in a balloon occupies 2.25 L at 298 K and 300 kPa. At
o-na [289]

If a gas in a balloon occupies 2.25 L at 298 K and 300 kPa, the temperature at which the balloon expand to 3.50L and 2.17 atm is 345.23K.

<h3>How to calculate temperature?</h3>

The temperature of an ideal gas can be calculated using the following formula:

P1V1/T1 = P2V2/T2

Where;

  • P1 = initial pressure
  • P2 = final pressure
  • V1 = initial volume
  • V2 = final volume
  • T1 = initial temperature
  • T2 = final temperature

According to the information given in this question;

  • P1 = 300kpa = 2.96 atm
  • P2 = 2.17 atm
  • V1 = 2.25L
  • V2 = 3.50L
  • T1 = 298K
  • T2 = ?

2.96 × 2.25/298 = 2.17 × 3.5/T2

0.022T2 = 7.595

T2 = 7.595 ÷ 0.022

T2 = 345.23K

Therefore, if a gas in a balloon occupies 2.25 L at 298 K and 300 kPa. the temperature at which the balloon expand to 3.50L and 2.17 atm is 345.23K.

A technician prepared a solution by heating 100 milliliters of distilled water while adding KCl crystals until no more KCl would
almond37 [142]

Answer:

At lower temperatures the solubility of the KCl decreased and recrystallization occurred

Explanation:

Solubility refers to the amount of solute that dissolves in one litre of water at a particular temperature. Solubility is a property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called a saturated solution.

Solubility is dependent on temperature. This is the reason why we must state the particular temperature at which a given solubility data was collected. Above or below the quoted temperature, the solubility data may no longer be accurate.

Let's return to the question, at elevated temperatures, we can see that the KCl is very soluble in water as evidenced by the clear solution obtained at high temperature. However, as the temperature decreases, the solubility of KCl also decreases accordingly and recrystallization of the solute occurred hence the formation of a cloudy solution and the settling of some solid at the bottom of the flask.

A typical hydrogen peroxide solution from a drug store is labeled as 3.0% hydrogen peroxide. What is the other 97% of this compo
GarryVolchara [31]

Answer: Water

Explanation:

Chemically speaking, a solution has two components: solute and solvent.

The <u>solute</u> is that substance (usually solid, but it can also be liquid or gas) that dissolves in a liquid substance and <u>its proportion in the resulting solution is usually less than the solvent. </u>

The <u>solvent</u> is the substance used to <u>dissolve the solute, and generally its proportion in the resulting solution is greater.</u> Being the most common used  solvent water.

This means that in a solution there is usually more solvent than solute.

So, in the case of the hydrogen peroxide solution, since the proportion is 3\% to 97\%, the hydrogen peroxide is the solute and water is the solvent.
