What happens to the boiling point of hydrocarbon compounds when the number of carbon atom increases

1 answer:

3 0

The boiling points of alkanes increases with increasing number of carbons. This is because the intermolecular attractive forces, although individually weak, become cumulatively more significant as the number of atoms and electrons in the molecule increases.

So therefore your answer choice will increase. (B)

Which statement explains why water is classified

hichkok12 [17]

Answer: Option (1) is the correct answer.

Explanation:

Compounds are the substances which contain two or more different elements.

Similarly, water is a compound as it is made up when two hydrogen atoms combine with one oxygen atom. Compounds can be broken down with the help of chemical reactions.

Hence, the statement water can be broken down by chemical means explains why water is classified as a compound.

How many milliliters of a 1.5 m h2so4 are needed to neutralize 35ml sample of a 1.5 m solution?

DochEvi [55]

Answer:

1) 17.5 mL

Explanation:

Hello,

In this case, the reaction between sulfuric acid and potassium hydroxide is:

$H_2SO_4+2KOH\rightarrow K_2SO_4+2H_2O$

In such a way, we notice a 1:2 molar ratio between the acid and the base, therefore, at the equivalence point we have:

$2*n_{acid}=n_{base}$

And in terms of concentrations and volumes:

$2*M_{acid}V_{acid}=M_{base}V_{base}$

Thus, we solve for the volume of acid:

$V_{acid}=\frac{M_{base}V_{base}}{2*M_{acid}} =\frac{35mL*1.5M}{2*1.5M} \\\\V_{acid}=17.5mL$

Best regards.

What are the prompt neutrons that occur during nuclear fission?

zysi [14]

Answer:

Prompt Neutrons

Explanation:

Principle. Using uranium-235 as an example, this nucleus absorbs thermal neutrons, and the immediate mass products of a fission event are two large fission fragments, which are remnants of the formed uranium-236 nucleus. These fragments emit two or three free neutrons (2.5 on average), called prompt neutrons.

Please help thank you

maxonik [38]

Answer:

$K=1.7x10^{-3}$

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to solve this problem by firstly setting up the equilibrium expression for the given reaction, in agreement to the law of mass action:

$K=\frac{[NO]^2}{[N_2][O_2]}$

Next, we plug in the given concentrations on the data table to obtain:

$K=\frac{(0.034)^2}{(0.69)(0.98)}\\\\K=1.7x10^{-3}$

Regards!
