Complete the lewis dot structure for h2co (in which both h atoms are bonded to c).

On the attached picture.

Explanation:

Hello,

Formic acid is a carboxylic acid composed by one carbon, one oxygen and two hydrogens whose Lewis dots structure is shown on the attached picture wherein a double bond is present between the carbon and the oxygen, and two single bonds between the carbon and each hydrogen. Consider that oxygen has two bonded valence electrons and 4 non-bonded electrons in order to attain and accomplish the octate.

Best regards.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
