Answer:

Whichever one of your answer options does not have a molcular formula of C5H12. It's hard for me to tell what the answer options show.

Explanation:

Pentane is a 5-carbon alkane, meaning all carbon atoms are connected by single bonds. In pentane, all the bonds not occupied by carbon atoms are occupied instead by hydrogen atoms. In general, a quikc way of figuring out the molecular formula for an alkane is CnH(n+2), where n is the number of carbon atoms. If you have a molecular formula that does not follow this rule, either there is a different number of carbon atoms, or there is a double or triple bond between carbon atoms such that there are fewer bonds available for hydrogen atoms to occupy.

When a writer uses “common knowledge” in an essay, why does it NOT require a citation nor is it considered plagiarism?

Plagiarism is when you just copy exactly what someone else says, without their permission, or without citing where you got it from.
Common knowledge should be your own words. unless you take it from somewhere else, it doesnt need anything.

Five gases combined in a gas cylinder have the following partial pressures: 3. 00 atm (N2), 1. 80 atm (O2), 0. 29 atm (Ar), 0. 1

Helen [10]

The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.

The partial pressure has been defined as the pressure exerted by each gas in the mixture.

According to the Dalton's law of partial pressure, the total pressure of gas has been the sum of the partial pressure of the gases in the mixture.

The given partial pressure of gases in the mixture has been:
