The difference between Argon-38 and Argon - 45 is the number of neurons in their nuclei.

<h3>What is Isotope?</h3>

Isotopes are two or more types of atoms of the same element that have the same atomic number but differs in mass numbers due to different numbers of neutrons in their nuclei.

Argon atom with a mass number of 38 (Ar-38) - number of neutrons = 20

Argon atom with a mass number of 45 (Ar-45) - number of neutrons = 27

Thus, the difference between Argon-38 and Argon - 45 is the number of neurons in their nuclei.

The answer should be A, flammability.


The isotopes of the same element would result in the same chemical properties, as the number of protons and electrons are not changed, meanwhile, the physical properties would be slightly different with each other because they have different numbers of electrons.


Out of the 4 options, only option A is a chemical property. Chemical properties are the properties of an element reacting with other substances that creates new substances at the end. While physical properties are the ones that does not produces new substances or any reactions. They are usually observable and measurable.


Therefore, since flammability is a chemical property, the answer is A.

The solvolysis of t-butyl bromide in methanol yields 2-methylpropene in an E1 reaction (among other products). What is the effec
jolli1 [7]

Answer:

See explanation

Explanation:

For a reaction that proceeds by E1 mechanism, the rate determining step involves the formation of the carbocation.  

The rate of formation of this carbocation depends only on the concentration of the t-butyl bromide since it is the only specie that enters into the rate equation.

Hence, when the concentration of t-butyl bromide is tripled, the rate of reaction is tripled.

Methanol does not enter into the rate equation hence doubling its concentration does not affect the rate of reaction.

Svetradugi [14.3K]
Asexual reproduction involves the production of offspring without the need for a secondary partner to contribute genetic information.

Pollination and mating are two forms of sexual reproduction, so B, C, and D are incorrect. A, because the new potato grows directly from the old without the contribution of new genetic material, asexually reproduces.
