The alkanes are a homologous series of compounds containing only carbon and hydrogen that have the general formula

ps://tex.z-dn.net/?f=C_nH_%7B2n%2B2%7D" id="TexFormula1" title="C_nH_{2n+2}" alt="C_nH_{2n+2}" align="absmiddle" class="latex-formula">. Members of this series include butane (C₄H₁₀), 3,3-dimethylpentane (C₇H₁₆), hexane (C₆H₁₄), and heptane (C₇H₁₆).
The boiling points for a set of compounds in a homologous series can be qualitatively predicted using intermolecular force strengths. Using their condensed structural formulas, rank the homologous series for a set of alkanes by their boiling point.

Answer:

Heptane > hexane> 3,3-dimethylpentane > butane

Explanation:

All things being equal, it is expected that the boiling point of the members of the alkane homologous series increase as we move down the group.

Hence for example, butane is expected to have a higher boiling point than ethane. Another important factor we would be considering in this answer is the presence of a branched alkane amongst the answers in the question. A straight-chain alkane will have a boiling point which is higher than that of a branched-chain alkane due to the greater surface area in contact, thus the greater van der Waals forces, between adjacent molecules

Now if we are to rank the compounds on the basis of boiling point, the answer is as follows:

Heptane > hexane > 3,3-dimethylpentane> butane

The reaction is called chain reaction when
Maru [420]

Answer:

c. it involves a series of steps, each of which generates a reactive intermediate that brings about the next step

Explanation:

A chain reaction consist of many repeating steps. Chain reaction will never stop until all the reactant has been exhausted. It is more of a cycle of reaction that generate a reactive intermediate that brings about the next step.

Example of a chain reaction is the chlorination of methane.

CH4 + Cl2  ↔ CH3Cl + HCl

CH3Cl  + Cl2  ↔ CH2Cl2 + HCl

CH2Cl2 + Cl2  ↔ CHCl3 + HCl

CHCl3 + Cl2  ↔ CCl4 + HCl

10.Which device is designed to produce
andreev551 [17]

Which device is designed to produce mechanical energy?

Well, mechanical energy is the sum of potential and kinetic energy. Kinetic energy is a unit of energy in which is the reason why an object does movement, while potential energy is another unit of energy in which is the reason why an object doesn't move, or stops. While you can stop a fan or a lamp, it isn't automatic. It's manually. So the answer is (4) an oven because mechanical energy happens automatically, not manually, or for a greater reason.

How many ions are there in 0.187 mol of Na+ ions
kondaur [170]
Best Answer
1 mole of a substance contains 6.022x10^23 "units" of that substance.

So 0.187 mol of Na+ is 1.13x10^23 ions (6.022x10^23 x 0.187).
