B) Ethane has the formula C2H6. In terms of electronic structure,
k0ka [10]

Answer:

There is one single covalent bond between two carbon atoms.

Explanation:

We know that sharing of electrons form covalent bonds.

If we look upon K,L,M ,N shells of the carbon and hydrogen atoms.

We found that Hydrogen is having only  1 electron in K shell.

And Carbon on the other hand is having 2 electrons in K shell and 4 electrons in L shell.

So carbon have  4 valence electrons,and it can share 4 bonds with any relevant atom to complete its octet.

And Hydrogen requires  1 electron to complete its doublet.

Alkane general formula C_{n}H_{2n+2}

For ethane n=2

C_{2}H_{4+2} = C_{2}H_{6}

1 Carbon atom is shared by  3 Hydrogen.

The remaining one electron (4-3)=1 of carbon will be shared with another carbon atom.

An image of the sharing of electrons attached below,

Hence we have only  1 covalent bond between the two.

Vitamin C contains the elements C, H, and O. It is known to contain 40.9% C and 4.58% H by mass. The molar mass of vitamin C has
soldier1979 [14.2K]

Answer:

C₆H₈O₆

Explanation:

First off, the<u> percent of oxygen by mass</u> of vitamin C is:

  • 100 - (40.9+4.58) = 54.52 %

<em>Assume we have one mol of vitamin C</em>. Then we would have <em>180 grams</em>, of which:

  • 180 * 40.9/100 = 73.62 grams are of Carbon
  • 180 * 4.58/100 = 8.224 grams are of Hydrogen
  • 180 * 54.52/100 = 98.136 grams are of Oxygen

Now we <u>convert each of those masses to moles</u>, using the <em>elements' respective atomic mass</em>:

  • C ⇒ 73.62 g ÷ 12 g/mol = 6.135 mol C ≅ 6 mol C
  • H ⇒ 8.224 g ÷ 1 g/mol = 8.224 mol H ≅ 8 mol H
  • O ⇒ 98.136 g ÷ 16 g/mol = 6.134 mol O ≅ 6 mol O

So the molecular formula for vitamin C is C₆H₈O₆
