How many electrons does it take to fill the outer energy level of most atoms

A small gas cylinder of Helium can be used to fill many more balloons than would fit inside it. Explain how this works, in your

Fudgin [204]

<h2>Gas Molecules Move in Random Motion </h2>

Explanation:

According to the property of an ideal gas the volume occupied by the gas molecules themselves is negligible as compared to the volume occupied by the gas
The molecules of ideal gas obey Newton's laws of motion thus they move in random motion
According to the above statements we can conclude that Helium gas can fill many more balloons as compared to fit the baloons inside the cylinder because the particles of gas is free to move in random motion and can occupy more volume

Carbon tetrachloride, CCl4, once used as a cleaning fluid and as a fire extinguisher, is produced by heating methane and chlorin

Elena-2011 [213]

Answer:

1.882 g

Explanation:

Data Given

mass of Cl₂ = 33.4 g

mass of CH₄ = ?

Reaction Given:

CH₄+ 4Cl₂ --------→ CCl₄ + HCl

Solution:

First find the mass of CH₄ from the reaction that it combine with how many grams of Chlorin.

Look at the balanced reaction

CH₄ + 4Cl₂ --------→ CCl₄ + 4HCl

1 mol 4 mol

So 1 mole of CH₄ combine with 4 moles of Cl₂

Now

convert the moles into mass for which we have to know molar mass of CH₄ and Cl₂

Molar mass of Cl₂ = 2 (35.5)

Molar mass of Cl₂ = 71 g/mol

mass of Cl₂

mass in grams = no. of moles x molar mass

mass of Cl₂ = 4 mol x 71 g/mol

mass of Cl₂ = 284 g

Molar mass of CH₄= 12+ 4(1)

Molar mass of CH₄= 16 g/mol

mass of CH₄

mass in grams = no. of moles x molar mass

mass of CH₄= 1 mol x 16 g/mol

mass of CH₄ = 16 g

So,

284 g of Cl₂ combine with 16 g of methane ( CH₄ ) then how many grams of CH₄ is needed to combine with 33.4 g of Cl₂

Apply unity Formula

284 g of Cl₂ ≅ 16 g of methane ( CH₄ )

33.4 g of Cl₂ ≅ X g of methane ( CH₄ )

By cross multiplication

X g of methane ( CH₄ ) = 16 g x 33.4 g / 284 g

X g of methane ( CH₄ ) = 1.88 g

1.882 g of methane (CH₄) will needed to combine with 33.4 g of Cl₂

So

methane (CH₄) = 1.882 g

Which of the following represents the ground state electron configuration for the Mn3 ion?

Allisa [31]

Answer:

$1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^2$

Explanation:

The $Mn^{+3}$ has 22 electrons arround the nucleous. Its ground state configuration following the diagonal rule is:

$1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^2$

In term of the previous noble gas:

$[Ar] 4s^2 3d^2$

Why is it important to have 6 carbon dioxide entering the chloroplast?

vekshin1

If there is a number other than 6 carbon dioxide then photosynthesis would not occur. Without photosynthesis many plants would die from not making food.

6CO2 + 6H2O ------> C6H12O6 + 6O2

One characteristic of a scientific theory is that____

Sladkaya [172]

Answer: it should be as simple and logical as possible.

Explanation: when producing a scientific theory, one shouldn't introduce stretched realities. For example, if I come back home and find the fridge open, it's very unlikely that a pink elephant came into my house while I was gone and opened it, I must have left it open when I left.
