Which method would increase the solubility of a gas

Chemistry

Increasing the partial pressure of the gas over the liquid or lowering the temperature of the liquid can increase the solubility of a gas in a liquid

Explanation:


Liquids and solids exhibit much no modification of solubility with changes in pressure. Gases as may well be expected, increase in solubility with a rise in pressure. law states that: The solubility of a gas during a liquid is directly proportional to the pressure of that gas on top of the surface of the solution.

Increasing the partial pressure of the gas over the liquid or lowering the temperature of the liquid can increase the solubility of a gas in a liquid. I hope this. Let me know if anything is unclear or if you want any further explanation.

2 Which chemical reaction is exothermic and why A 25 degrees after 25 minutes B 23 degrees after 15 minutes C 30 degrees after 2
baherus [9]

Answer:

C 30 degrees after 25 minutes

Explanation:

A reaction is exothermic if heat is evolved as the reaction proceeds. How do we know if heat was given out in the course of the reaction? We have to measure the temperature of the system using a thermometer as  the reaction progresses.

If the temperature becomes higher than room temperature (25 degrees), we can now conclude that the reaction is exothermic and heat was indeed given out during the course of the reaction.

Why would you get electrocuted if you went swimming in a pool during an electrical storm?
fredd [130]

Answer:

In a swimming pool chlorine ion are mix with water, a polar molecule. In this case the pool is a perfect environment for the conductive solution. The reason why, people can be electrocuted is that the hypochlorite is an ion and in the water, it form an ionic compound.

PLZ HELP THIS IS DUE TODAY!!!!!!
Goshia [24]
It would be letter C, because the molecules of solids can have a little vibration in their places.
The first one is for gas, so it's wrong. The second one is for liquids. And finally, the third one is right.

If you digested 25 mg of pure ferrocene in nitric acid and then diluted the resulting solution up to 500 mL with 1% aqueous hydr
Vilka [71]

Answer:

1.345*10⁻⁴ mol/L

15.023 mg/L

Explanation:

The chemical <u>formula of ferrocene</u> is Fe(C₅H₅)₂, thus its molecular weight is:

55.845 g/mol + 10*12g/mol + 10 *1g/mol = 185.845 g/mol

  • The moles of Fe contained in 25 mg (or 0.025 g) of ferrocene are:

0.025gFerrocene*\frac{1molFerrocene}{185.845g} *\frac{1mol Fe}{1molFerrocene}=1.345*10^{-4} molFe

  • The final volume is 500 mL, or 0.5 L. So the iron concentration in mol/L is:

\frac{1.345*10^{-4}molFe}{0.5L}= 2.69*10^{-4} mol/L

  • We can convert that value into mg/L:

2.69*10^{-4} \frac{molFe}{L} *\frac{55.845g}{1molFe}*\frac{1000mg}{1g}=15.023 mg/L

a jar of crunchy peanut butter contains 1.43kg of peanut butter. if you use 8.0% of the peanut butter for a sandwich, how many o
chubhunter [2.5K]

Answer: 4.04 ounce

Explanation: Given: Peanut butter contained in the jar = 1.43 kg

Used Peanut butter=8.0 % of 1.43kg = \frac{8}{100}\times 1.43kg=0.1144kg

As we know 1kg=35.274 ounce

0.1144 kg=\frac{35.274}{1}\times 0.1144=4.04ounce
