The boiling point of hydrocarbons generally increases as the size of the molecules increases because more bonds are needs to be broken in larger organic molecules.
<h3>What are hydrocarbons?</h3>
Hydrocarbons are organic compounds which here composed of hydrogen and carbon alone.
Hydrocarbons are grouped into families or homologous series based on a reactive group known as the gincyiial group
The homologous series include

Answer:
V/V% = 8.2%
Explanation:
Given data:
Volume of methanol = 37.5 mL
Volume of solution = 456 mL
V/V% = ?
Solution:
V/V% = [volume of solute / volume of solution ]×100
V/V% = 37.5 mL / 456 mL × 100
V/V% = 0.08× 100
V/V% = 8.2%
The answer for the first question is A. Single covalent bond.
The answer for the second question is C. Carbon dioxide.
The answer to your question is liquid hydrogen
Answer:
What led him to change his outlook was because in his experiment, when he fired positively charged alpha particles at a piece of gold foil, he observed that some of the alpha particles were deflected to some degree, and some others bounced back directly toward him.
Explanation:
In his experiment, he fired positively charged alpha particles at a piece of gold foil.
Now, after doing that he observed that some of the alpha particles were deflected to some degree, and some others bounced back directly toward him.
After those observations, he felt that for the order of the alpha particles to have been deflected, they would possibly have been hit or come close to being hit by a positively charged particle in the atom. This made him to conclude that an atom consists mostly of empty space, with a very small and dense but positively charged nucleus at the center. And that this nucleus contains most of the mass of the atom, while the electrons orbit the nucleus.
