i may be wrong but Use the normal boiling points: propane, C3H8, –42.1˚C; butane, C4H10, –0.5˚C; pentane, C5H12, 36.1˚C; hexane, C6H14, 68.7˚C; heptane, C7H16, 98.4˚C; to estimate the normal boiling point of octane, C8H18.

Answer:

C₄H₁₀ > C₃H₈

Explanation:

Propane (C₃H₈) is symmetrical and non-polar, so the only inter-molecular forces are London dispersion forces.

Butane (C₄H₁₀) is symmetrical and non-polar, so the only inter-molecular forces are also London dispersion forces.

The only difference is the size.  Butane has more atoms, more surface area, and therefore more inter-molecular forces.  So it has a higher boiling point.

C₄H₁₀ > C₃H₈

A shiny chunk of metal is found to have a mass of 37.28g. The metal is dropped into a graduated cylinder which contains 20.0 mL
Amanda [17]

Answer: The density of the material is 2.66 g/mL and it is likely this  is made of Aluminum

Explanation:

The first step to know the material of the chunk of metal is to calculate its density. The general formula for density is P (density) = \frac{m (mass)}{ v (volume)}. Moreover, in this case, it is known the mass is 37.28 g, but the volume is not directly provided. However, we know the water in the graduated cylinder had a volume of 20.0 mL and this increased to 34.0 mL when the chunk of metal is added, this means the volume of the metal is 14 mL (34.0 mL - 20.0 mL = 14 mL). Now let's calculate the density:

P = \frac{37.28g}{14.0mL}

P = 2.66 g/mL

This means the density of this metal is 2.66 g/mL, which can be rounded as 2. 7 g/mL, and according to the chart, this is the density of aluminum. Therefore, this material of this chunk is aluminum.

Fluorine has an atomic number of 9, how many electron shells does it have?
aleksandr82 [10.1K]
2 shells because if you do the electronic configuration: 
 2,7 which adds up to 9
7 stands for the group it in and it also stands for how many electrons are in the outer shell.
the amount of spaces stands for which period its in therefore it in period 2

Please help! I have no idea what a galactic symbol is. It says it on one of my science assignments and I'm confused. All I know
Ilya [14]
Hey, its alright bro! I gotchu.

Im pretty sure the galactic symbol is the same reference to the symbol of the element on the periodic table.
For an example (Hydrogen) is H 
So if im correct im pretty sure its referring to the symbols for each element

Hopefully this helps
