Answer:

Octane

Explanation:

Hydrocarbons are composed of carbon and hydrogen atoms and are generally non-polar. The only intermolecular force of attraction between hydrocarbons is the weak van der waals interaction. Longer the hydrocarbon chain, stronger will be this interaction.

In the given options:

Propane = C3H8

Octane = C8H18

Hexane = C6H14

Ethane = C2H6

Thus, octane is has the longest chain and will have the strongest van der waal interaction which will allow the molecule to stay in a liquid state longer.

I just took a test with this question and got the answer wrong for saying ethane. The correct answer is propane.

Plz answer thx<br><br><br> How many moles are in 2.5 x 10^18 grams of water?

alex41 [277]

Answer:

$1.39\times 10^{17}$ moles of water in $2.5\times 10^{18} g$ of water.

Explanation:

Mass of water = $m = 2.5\times 10^{18} g$

Molar mass of water = M = 18 g/mol

Moles = n = $\frac{m}{M}$

$n=\frac{2.5\times 10^{18} g}{18 g/mol}=1.39\times 10^{17} moles$

So, there are $1.39\times 10^{17}$ moles of water in $2.5\times 10^{18} g$ of water.

When driving your car, you hear a squeal every time you press the brakes. You decide the problem is that there's a mouse trapped

Hypothesis because law don’t make sense and theory is for something that already has data behind it. In this case you don’t do it’s not hypothesis
