The branch of chemistry that the chemist might use will be the branch of <em>organic chemistry</em>. This is because gasoline is an organic compound. We can say that a compound is organic if it contains a carbon atom. Gasoline is composed of long chains of alkanes (hydrocarbons with single bonds) ranging from 4 carbon atoms to 12 carbon atoms.
Answer:
C
Explanation:
C because there is more in it than the rest of the idems
-0° freezing point ice or ice cream
B
The emission spectrum of an element is identical to its absorption spectrum.
Explanation:
This is because a quantum leap of an electron of an atom from one lower energy level to a higher one results in the absorption of a specific wavelength of electromagnetic radiation. When the electron leaps back to the lower energy level, it releases the same wavelength of electromagnetic radiation. This is according to Bohr's theory. Every atom has a signature absorption and emission spectra that are used to identify it.

Answer:
Explanation:
Force can be found by multiplying the mass and the acceleration.
The mass of the sled is 300 kilograms and the acceleration is 2 meters per second squared.
Multiply.
1 kilogram-meter per second squared is equal to 1 Newton. Therefore, 600 kilograms-meter per second squared is equal to 600 Newtons.
The force used on the sled is 600 Newtons.
