Volatility and vapor pressure are ________. Volatility and vapor pressure are ________. not related directly proportional to one

another both independent of temperature the same thing inversely proportional to one another
Chemistry

alina1380 [7]3 years ago

Answer:

directly proportional to one another

Explanation:

Volatility refers to how quickly a substance changes from liquid to gas.

If a substance has a high vapour pressure, the substance is highly volatile. Similarly, if a substance has a low vapour pressure, then the substance is much less volatile.

This implies that volatility and vapour pressure gives a direct proportionality.

What is the solubility of salt in water at room temperature
rewona [7]
<h3><u>Answer;</u></h3>

357 mg/mL

<h3><u>Explanation;</u></h3>
  • Solubility is defined to be the maximum amount of solute that will dissolve in a given amount of solvent at a specific temperature. The solubility of a salt is one of many physical properties that depend on temperature.
  • At room temperature 25 °C, the solubility of salt or Sodium Chloride is 357 mg/mL.
  • For many solutes, increasing the temperature increases the solubility of the solute. The solubility of sodium chloride or table salt is only slightly affected by temperature increase.

Calculate the mass of water produced by metabolism 84.0 g of glucose
scoundrel [369]

The amount of water that will be produced is 50.36 grams

<h3>Stoichiometric problems</h3>

The metabolism of glucose is represented by the following equation:

C_6H_1_2O_6(s)+6O_2(g)--- > 6CO_2(g)+6H_2O(g)

The mole ratio of glucose metabolized to the water produced is 1:6.

Mole of 84.0 g glucose = 84/180.156 = 0.4662 moles

Equivalent mole of water = 0.4662 x 6 = 2.7975 moles

Mass of 2.7975 moles water = 2.7975 x 18 = 50.36 grams

PLEASE HELP
otez555 [7]

Answer:

P2≈393.609Kpa so I think the answer is 394 kPa

Explanation:

PV=mRT Ideal Gas Law

m and R are constant because they dont change for the problem. That means

PV/T=mR = constant

so P1*V1/T1=P2*V2/T2 and note that the temperatures are in absolute temperatures (Kelvin) because you can't divide by zero.

So P2 = P1*V1*T2/(V2*T1) = 101325 Pa * 700 mL * 303K/(200 mL*273K)

P2 = 393609 Pa

What does a most-favored-nation (MFN) status mean?
MatroZZZ [7]

Most Favored Nation status is an economic position in which a country enjoys the best trade terms given by its trading partner. That means it receives the lowest tariffs, the fewest trade barriers, and the highest import quotas (or none at all).

I got this from google, hope it helps! :)
