Predict the approximate molecular geometry of a formaldehyde molecule:

trigonal planar geometry

Explanation:

The molecule, formaldehyde , has three regions of electron density around the molecule. The carbon atom is the central atom in the molecule of formaldehyde.

Recall that each bond around the central carbon atom in formaldehyde- both single and double are counted as a single region of electron density. Molecules having three regions of electron density around the central atom have a trigonal planar geometry.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

if you mean hydrogen and oxygen then water is the product
