Argon has three naturally occurring isotopes: argon-36, argon-38, and argon-40. Based on argon's reported atomic mass, which isotope do you think is the most abundant in nature? Explain.

Answers

Answer 1

Answer:

argon-40

Explanation:

The relative atomic mass of Argon is 39.948. This is very close to the mass of argon-40. Usually, the relative atomic mass of an element is the sum of the percentage abundance of each isotope in nature multiplied by its mass. The result of this sum is normally biased towards the isotope with the highest abundance. In the case of argon, argon-40 must have the highest abundance, hence the value of the relative atomic mass.

Answer 2

Answer:

Argon-40 is the most abundant isotope of argon in nature because the reported atomic mass of argon is closer to 40 atomic mass units.

Given that argon has three naturally occurring isotopes: argon-36, argon-38, and argon-40, compare their masses to determine which one is most likely to contribute the most to the average atomic mass of argon.

The atomic mass of argon is typically given as approximately 39.95 atomic mass units (u). This value is a weighted average of the masses of the different isotopes of argon, taking into account their relative abundance in nature.

Argon-36 has a mass of approximately 36 atomic mass units.

Argon-38 has a mass of approximately 38 atomic mass units.

Argon-40 has a mass of approximately 40 atomic mass units.

Since the reported atomic mass of argon is closer to 40 atomic mass units, it suggests that argon-40 is the most abundant isotope of argon in nature.

The combustion of fossil fuels releases ____ into the atmosphere. oxygen

gasoline

carbon

glucose

Answers

Answer: The correct answer is carbon.

Explanation:

Combustion reaction is defined as the reaction in which a hydrocarbon burns in oxygen or reacts with oxygen gas to produce carbon dioxide and water molecule.

Fossil fuels are defined as the hydrocarbons which mainly contains coal, fuel oil, natural gas etc..

When fossil fuels are burned in air, it mainly releases carbon dioxide, sulfur dioxide, methane, nitrous oxide etc..

The major component released during the combustion of fossil fuels is carbon.

Hence, the correct answer is carbon.

In nuclear reactions, which of the following is likely to occur? Some of the mass is converted to energy.
The products can weigh less than the reactants.
There is no loss of mass in the reaction.
a and b

Answers

Answer:

A. Some of the mass is converted to energy.

B.The products can weigh less than the reactants.

Explanation:

Nuclear reaction: A reaction in which a nuclei splits into two or more smaller nuclei of mass less than the reactants ,or two or more nuclei combined together to form heavy nuclei of mass less than the reactants and huge amount of energy released.

Nuclear reactions are of two types

1. Nuclear fission

2.Nuclear fusion

1. Nuclear fusion: A reaction in which two or more lighter nuclei combined together to form heavy nuclei of mass slightly less than the total mass of reactants and a large amount of energy released. Because the difference in mass of reactants and products change into energy .

2.Nuclear fission: A reaction in which a heavy nuclei splits into two or more lighter nuclei of total mass slightly less than the mass of reactant. Because the difference in mass of product and reactant change into energy therefore, a huge amount of energy released during this reaction.

Therefore, Option A and B are correct.

Answer : A. Some of the mass is converted to energy.

B.The products can weigh less than the reactants.

How many neutrons does an atom of
Copper have in its nucleus?

Answers

answer:34.55
explanation:number of neutrons=mass number-atomic number
the mass number for copper is 63.55 so you do 63.55-29 (29 is the atomic number) and you would get 34.55

4. Will have the same g.f.w

Answers

The answer is 1 and 3. The number of atoms per molecule of these three substance is not equal. So they will not contain same number of atoms. And for gas, under same condition with same number of moles will have the same volume. The g.f.w is related to the atomic mass. So they are different.

Which type of reaction occurs when nonmetal atoms become negative nonmetal ions?A. oxidation
B. reduction
C. substitution
D. condensation

Answers

Answer: Option (B) is the correct answer.

Explanation:

When an atom gains electrons then it becomes rich in electrons and therefore it acquires a negative charge.

Also, it is known that a reduction reaction is a reaction in which an element gain electron(s).

For example, $Br_(2) + 2e^(-) \rightarrow 2Br^(-)$ is a reduction reaction.

Thus, we can conclude that when nonmetal atoms become negative nonmetal ions then type of reaction which occurs is reduction reaction.

The answer is B. reduction. The atom becoming negative ions means it gains electrons. The reaction which gain electrons is reduction reaction. So the answer is B.
