If a straight-chain hydrocarbon is a gas at room temperature, how many carbon atoms will it have?

1 answer:

6 0

The fewer the carbon atoms, the closer it is to being a gas. The only one you have to check out is A which is hexane. You know that gasoline at the pumps has 8 carbons and its a liquid. So B and C are both not gases because they are above 8.

C6 (hexane) is a liquid at room temperature not a gas.

The answer is D. If there is a gas present, it must be C3

PLEASE HELP: You have been given 2.42 moles of beryllium sulfide (BeS), determine the mass in grams of beryllium sulfide that yo

Alecsey [184]

The mass in grams of the given beryllium sulfide is 99.2 g. The correct option is the second option - 99.2 g BeS

<h3>Calculating mass of a compound </h3>

From the question, we are to determine the mass of the given beryllium sulfide.

From the given information,

Number of moles of beryllium sulfide (BeS) given = 2.42 moles

Using the formula,

Mass = Number of moles × Molar mass

Molar mass of BeS = 41 g/mol
