How many electrons does one neutrally charged atom of argon have?
padilas [110]

Answer:

A. 18

Explanation:

A neutral charged atom is an atom with 0 charge.

Anyway, first look at the periodic table and find Argon.

After you find Argon, look at its Atomic number.

Its Atomic number is 18.

And a neutral atom of Argon has 0 charge.

So we need 18 electrons for Argon to cancel out and become neutral.

Basic math:

18 +( -18) = 0

Therefore, the correct answer is A. 18

Hope it helped!

q6- convert the fisher projection of the following amino acid into a line structure. label the chiral center on the line structu
Vera_Pavlovna [14]

Fisher projection is the representation of organic molecule in2-D without destroying the3-D stereochemical information.

<h3>What does a Fischer projection in organic chemistry mean?</h3>

A Fischer projection is a drawing technique used in organic chemistry to depict molecules in two dimensions while maintaining the three-dimensional stereochemical information regarding the absolute arrangement at chiral centers.

<h3>What sets the Fischer projection apart from the Haworth projection?</h3>

In contrast to Fischer projections, which are used to represent sugars in their open-chain form, Haworth projections are typically employed to represent sugars in their cyclic forms.

The reaction 2CH4(g)⇌C2H2(g)+3H2(g) has an equilibrium constant of K = 0.154. If 6.30 mol of CH4, 4.20 mol of C2H2, and 11.15 mo
boyakko [2]

Answer:

C₂H₂ + 3H₂ ⟶ 2CH₄  

Explanation:

The initial concentrations are:

[CH₄] = 6.30 ÷ 6.00 =   1.05  mol·L⁻¹

[C₂H₂] = 4.20 ÷ 6.00 = 0.700 mol·L⁻¹

   [H₂] = 11.15 ÷  6.00 =  1.858 mol·L⁻¹

                2CH₄ ⇌ C₂H₂ + 3H₂

I/mol·L⁻¹:    1.05     0.700   1.858

Q = \dfrac{\text{[C$_{2}$H$_{2}$][H$_{2}$]}^{3}}{\text{[CH$_{4}$]}^{2}} = \dfrac{ 0.700\times 1.858^{3}}{1.05^{2}}= 4.07

Q > K

That means we have too many products.

The reaction will go to the left to get rid of the excess products.

C₂H₂ + 3H₂ ⟶ 2CH₄
