A carbon compound is made up of two parts: R−F, where R is the hydrocarbon part and F is the functional group part.
So, this R (hydrocarbon) part determines the physical properties of a compound and the F (functional group) part determines the chemical properties of the compounds.
In chemistry, there is a common note that says, "Like dissolves like".
This pertains to the concept that polar substances can dissolve only other polar substances. Also, nonpolar substances are also only able to dissolve nonpolar substances.
Polarity of the substance depends primarily on the type of bond and the difference in electronegativity.
Water is a polar substance while vegetable oil is not. From the concept presented above, it may be concluded that water will not be able to dissolve the vegetable oil and the assumption is logical.

Took the test and got this right. :)
The substances for moving things is that they are in motion which is Kinetic Energy
Answer:
The answer to your question is the number 4. 1.53175 L
Explanation:
Data
Volume 1 = V1 = 557 ml
Concentration 1 = C1 = 11 M
Volume 2 = V2 = ?
Concentration 2 = C2 = 4 M
Formula
Volume 1 x Concentration 1 = Volume 2 x Concentration 2
or V1 x C1 = V2 x C2
Solve for V2 V2 = V1 x C1 / C2
-Substitution
V2 = (557)(11) / 4
-Simplification
V2 = 6127 / 4
-Result
V2 = 1531.75 ml or 1.53175 L
Conclusion
557 ml of 11 M must be diluted to 1.53175 L
