The volume of a gas filled balloon is 22L at 313K and 1.5 atm. What would the volume be at 273K and 1 atm?

Answers

Answer:

28L

Explanation:

V1 = 22L                             V2 = ?

T1 = 313K                            T2 = 273K

P1 = 1.5atm                          P2 = 1.0atm

Using the combined gas law equations;

[tex]\frac{P1V1}{T1}= \frac{P2V2}{T2}[/tex]

∴[tex]V2 = \frac{P1V1}{T1} * \frac{T2}{P2}[/tex]

         = [tex]\frac{1.5*22}{313} * (\frac{273}{1})[/tex]

   V2 = 28L

From the calculations and the statement of the general gas equation, the volume of the gas becomes 28.8 L

What are gas laws?

The gas laws are used to show the relationship between the variables in problems that has to do with gases.

In this case, we have to apply the general gas law as follows;

P1V1/T1 = P2V2/T2

P1V1T2 = P2V2T1

V2 =   * 22L *  1.5 atm * 273K/313K * 1 atm

V2 = 28.8 L

The correct structure that corresponds to the name 2,2,3-trichloro-3-fluorohexane is both. Thus option C is correct.

What is chemical structure?

Chemical structure is defined as the physical configuration of atoms within a molecule. The molecular geometry of the molecule is determined by its chemical structure. By illustrating how the atoms and chemical bonds are arranged in space within the molecule, chemical structure can be used to establish the molecular geometry of a product. Chemists can now see a crucial visual depiction of a chemical formula thanks to this.

2,2,3-trichloro-3-fluorohexane structure given is both are correct as one of the structure is trans form and the other is cis form of the structure. Option A is trans form while option B is cis form of structure.

Thus, the correct structure that corresponds to the name 2,2,3-trichloro-3-fluorohexane is both. Thus option C is correct.

What is the IUPAC name of the compound N2O?

Answers

Answer:

Nitrous Oxide

Explanation:

A.
Select the correct structure that
corresponds to the name.
heptane
B.
CH3(CH2)4CH3

Answers

Answer:

Only A., the stick structure with no branches and five vertices between the two endpoints.

Explanation:

An alkane is a saturated hydrocarbon compound with no branches- just a series of carbon atoms connected with [tex]{\rm C}-{\rm C}[/tex] single bonds. Heptane is the name for an alkane with [tex]7[/tex] carbon atoms (the prefix "[tex]\verb!hept-![/tex]" means "seven".)

Notice that there are only [tex]6[/tex] carbon atoms in the alkane with the condensed structure formula [tex]{\rm CH_{3}}({\rm CH_{2})_{4}{\rm CH_{3}}[/tex]. The name for that structure would be hexane, not heptane.

In general, the condensed structure formula of an alkane with [tex]n[/tex] carbon atoms ([tex]n > 2[/tex]) is [tex]{\rm CH_{3}}({\rm CH_{2}})_{n-2} {\rm CH_{3}}[/tex]. The correct condensed structure formula for heptane ([tex]n = 7[/tex]) would be [tex]{\rm CH_{3}}({\rm CH_{2}})_{5} {\rm CH_{3}}[/tex].

The structure in choice A is represented as a line-angle formula. As long as no letter is present in the formula, each vertex in the line-angle formula (including the endpoints) represents a carbon atom. Hence, the line-angle formula in choice A would represent a hydrocarbon with [tex]7[/tex] carbon atoms.

A single line denotes a single bond between atoms. All [tex]7[/tex] carbon atoms in this structure are thus joined in a line with [tex]{\rm C}-{\rm C}[/tex] single bonds. Hence, this structure denotes an alkane with [tex]7[/tex] carbon atoms- heptane.
