Which of the following symbols represents a chlorine ion with a stable arrangement of eight valence electrons?

frozen [14]

A stable arrangement of eight valence electrons : ³⁵Cl⁻¹

<h3>Further explanation</h3>

Chlorine is a halogen gas, located in group 17, p block

Chlorine has an atomic number of 17 and an atomic mass of 35

Electron configuration: [Ne] 3s²3p⁵

If we look at the electron configuration, then Cl will bind 1 more electron so that the configuration is stable like Argon (atomic number 18)

So by binding this one electron, chlorine forms negative ions (anions)

³⁵Cl⁻¹

B. Cl⁻² binds 2 electrons, exceeding the octet rule

C. Cl⁺¹, releases 1 electron, remains unstable

D. Cl, the neutral form of Cl, is still unstable with a 7-electron valence configuration

A student weighs out 0. 0422 g of magnesium metal. The magnesium metal is reacted with excess hydrochloric acid to produce hydro

lutik1710 [3]

The student weighs out 0.0422 grams of the metal magnesium, thus we can figure that the more's, the magnesium he used, is the mass of the magnesium over the more mass, which is 0.024422.
That is approximately 0.001758.
Furthermore, it claims that too much hydrochloric acid causes the metal magnesium to react, producing hydrogen gas.
The volume of collected gas is 43.9 cc, the mastic pressure is 22 cc, and a sample of hydrogen gas is collected over water in a meter.

<h3>Is it true that calculations made utilizing experimental and gathered data result in a percent error? </h3>

Consequently, we are aware that magnesium and chloride react.
We create 1 as the reaction ratio is 1:2.
The hydrogen and 1 are more.
Magnesium chloride is more.
Therefore, based on this equation, we can infer that the amount of hydrogen that would be created in this scenario is greater than the amount of magnesium present here, or 0.001758 more.
Among hydrogen, there is.
\Once we convert the temperature from 32 Celsius to kelvin, we can tell you that the temperature is actually about 5.15 kelvin.
The gas has a volume of 43 in m, which is equal to 0.0439 liter and indicates that the pressure is approximately 832 millimeter.
Mercury, which is 2 times 13332 plus ca, or roughly 110922.24 par, is a mathematical constant.
So, in this instance, we are aware that p v = n r t.
The r in this case equals p v over n t, thus we want to determine the r.
So p is 110922.24. The temperature is 305.15 and the V is 0.04 over the n is 0.001758.
Let's proceed with the calculations right now.
In this instance, you will discover that the solution is 9.077 times 10; that is all there is to it.

How does the atmosphere help to make Earth livable? Check all that apply.

Likurg_2 [28]

Answer:

- contains oxygen

- provides warmth

- blocks harmful energy from the Sun

Explanation:

The atmosphere is crucial when it comes to providing living conditions on Earth. The gases in the atmosphere manage to balance the things just about right, so that the life can thrive. The atmosphere has oxygen, the gas that is used by pretty much every organism to be able to function. With its greenhouse gases, the atmosphere manages to trap the heat inside, thus providing warmth to the Earth. The numerous layers of the atmosphere manage to block in big portion the harmful energy from the Sun, with a special accent on the ozone layer, a layer that manages to stop most of the UV radiation.
