All of the noble gas elements except neon have 8 electrons in their outermost energy level. True or false

Answers

To solve this we must be knowing each and every concept related to element. Therefore, "all of the noble gas elements except neon have 8 electrons in their outermost energy level" is a false element.

What is element?

A chemical element represents a material that cannot be degraded chemically. Although chemical processes do not modify atoms, nuclear reactions can produce new elements.

Elements are classified according to the amount of protons they have. An element's atoms typically have the same amount of protons, but differing amounts of electrons or neutrons.

There are 118 recognized elements. Element 120.1 is being researched. When element 120 is created and validated, the periodic table must be updated to include it. A numerical subscript following an element in a chemical formula mean number of atoms. All of the noble gas elements except have 8 electrons in their outermost energy level.

Therefore, "all of the noble gas elements except neon have 8 electrons in their outermost energy level" is a false element.

False I think neon also has 8 electrons on it's outermost shell, I'm not rlly sure about that answer though.

Based on your own understanding and information in this lesson, what characteristics of the Confederate States of America made it a confederal government when compared to the government of the United States?

Answers

The main characteristic of the Confederate States of America that made it a confederal government when compared to the government of the United States was that its central power was much weaker.

Answer:

Exact answer (reword it yourself)

Explanation:

The Confederate States of America had a weaker central government than the United States, and individual states had more sovereignty and power that US states. The central government of the Confederate States handled only foreign issues or national economic issues.

A scientist wants to perform a controlled experiment to test the effect of rust on chemically treated iron. which action would be most important to perform in a controlled experiment? design an experiment that is based on previously published results. expose the treated iron to the corrosive effects of the air. test a large piece of treated iron and a small piece of untreated iron. test a piece of treated iron and a piece of untreated iron under the same conditions.

Answers

Answer: Option (d) is the correct answer.

Explanation:

A test or experiment in which only one variable is changed at a time in order to verify the result is known as a controlled experiment.

That is only independent variable need to be adjusted with respect to the dependent variable.

Thus, we can conclude that the action to test a piece of treated iron and a piece of untreated iron under the same conditions would be most important to perform in a controlled experiment in the given situation.

the answer is to test a piece of untreated and treated under same conditions!

The process of chemical cycling is known as a biogeochemical cycle. Why was it called biogeochemical cycle? A. absorbs the chemical involved from the sediment. B. takes place over a long period of time. C. involves both living and nonliving components. D. withdraws the chemical from the atmosphere as a gas.

Answers

I think the correct answer from the choices listed above is option C. Biogeochemical cycle is termed as such because these cycles involves both living and nonliving components. These cycles are the carbon cycle, water cycle, nitrogen cycle, phosphorus cycle, oxygen cycle, sulfur cycle and rock cycle.

Boyle’s law states that the volume of a gas is inversely proportional to its pressure if theA. temperature and number of particles are constant.
B. temperature reaches absolute zero.
C. number of particles decreases.
D. temperature and number of particles are doubled

Answers

Boyle's law states that the volume of a fixed mass of a gas is inversely proportional to its temperature if the temperature and the number of particles are constant.

Further Explanation

Boyles’s law

This gas law states that the volume of a fixed mass of a gas is inversely proportional to its pressure at constant absolute temperature.
Therefore, when the volume of an ideal gas is increased at constant temperature then the pressure of the gas will also increase.
Mathematically; Volume α 1/Pressure

Vα1/P

Therefore, constant k, is = PV

Other gas Laws

Gay-Lussac’s law

It states that at constant volume, the pressure of an ideal gas I directly proportional to its absolute temperature.
Thus, an increase in pressure of an ideal gas at constant volume will result to an increase in the absolute temperature.

Charles’s law

It states that the volume of a fixed mass of a gas is directly proportional to absolute temperature at constant pressure.
Therefore, an increase in volume of an ideal gas causes a corresponding increase in its absolute temperature and vice versa while the pressure is held constant.

Dalton’s law

It is also known as the Dalton’s law of partial pressure. It states that the total pressure of a mixture of gases is always equivalent to the total sum of the partial pressures of individual component gases.
Partial pressure refers to the pressure of an individual gas if it occupies the same volume as the mixture of gases.

Level: High school

Subject: Chemistry

Topic: Gas laws

Sub-topic: Boyle's Law

Final answer:

Boyle's law states the volume of a gas and its pressure are inversely related, given that temperature and number of particles are constant. Increased pressure leads to decreased volume and vice versa, providing temperature and the amount of gas remains the same.

Explanation:

Boyle's law, part of the field of Physics, specifically the subsection dealing with gas laws in Chemistry, states that the volume of gas is inversely proportionate to its pressure, under the condition that the temperature and number of particles of gas are constant. This means if the pressure of a gas increases, its volume decreases and vice versa. To clarify, let's consider an example. If you have a balloon filled with air (the gas), when you squeeze it (increasing pressure), the balloon gets smaller (volume decreases). However, this law only holds when the temperature and the number of gas particles are constant; no additional gas is added, nor heat.
