Answer:

Scenario B

Explanation:

In Scenario B; Yuki reads an article in the Professional Journal of Medicine stating that ginger root can help prevent some types of cancer. The article was published in a professional journal. Manuscripts sent to professional journals for publication must pass through a peer review process in order to ascertain the reliability of the data presented.

Magazine articles may not go through a peer review process since it is not written for the consumption of a professional audience.

A sample of oxygen gas (O2) has a volume of 7.51 L at a temperature of 19°C and a pressure of 1.38 atm. Calculate the moles of O
Maslowich

Answer: 0.43molO₂

Explanation:

The ideal gas law for moles is n=\frac{PV}{RT}. If you did not know, R is the ideal gas constant, 0.0821\frac{L*atm}{mol*K}.

Since the temperature must be in Kelvin, we must convert our given temperature from ℃ to K. 19C+273=292K

Now that we have the temperature converted to Kelvin, we can plug in our information to the ideal gas law for the number of moles.

n=\frac{PV}{RT}

n=\frac{1.38atm*7.51L}{0.0821\frac{L*atm}{mol*K} *292K} =0.43molO_{2}

n=0.43molO_{2}

Therefore, the number of moles is 0.43molO₂.

I hope this helps! Pls mark brainliest!! :)
