Draw the Lewis structures for CH3OH, CH2O and HCOOH. Indicate the hybrid orbital used in the sigma bonds for each of the carbon
sdas [7]

Answer:

See figure 1

Explanation:

For this question, we have to remember that in the lewis structures all atoms must have<u> 8 electrons</u>. And each atom would have a different value of <u>valence electrons</u>:

Carbon => 4

Oxygen=> 6

Hydrogen=> 1

Additionally, for the <u>hybridizations</u> we have to remember that:

Sp^3=> 4 single bonds

Sp^2=> 1 double bond

Sp^1=> 1 double bond

With this in mind, the formaldehyde and formic acid would have Sp^2 carbons and the ethanol an Sp^3 carbon.

Finally, for the oxidation state. We have to remember that <u>if we have more bonds with oxygen, we will have more oxidation</u>. Therefore, the carbon that has more oxidation is the one in the formic acid (we have several bonds with oxygen).

See figure 1

I hope it helps!

The sum of the protons and neutrons in an atom equals the?
Shalnov [3]

Answer:

mass number

Explanation:

The sum of the protons and neutrons in an atom equals the mass number of such an atom.

  • Mass number is the mass of an atom.
  • The mass of an atom is concentrated in the nucleus
  • The particles in the nucleus are the protons and neutrons.

So;

Mass number = number of protons + number of neutrons.
