Carbon is a fascinating element that is capable of forming four covalent bonds. Remembering molecular geometry, an element bonded to four separate atoms forms a symmetrical tetrahedron. When the elements are either carbon or hydrogen the molecule is nonpolar. Nonpolar compounds are insoluble in water. Examples of this includ

Without stratospheric ozone (O3), harmful solar radiation would cause gene alterations. Ozone forms when O2 breaks and each O atom reacts with another O2 molecule. It is destroyed by reaction with Cl atoms formed when the C-Cl bond in synthetic chemicals breaks. Find the wavelengths of light that can break the C-Cl bond AND the
Why production of certain vapors would be reduced when a mixture of methanoic acid, ethanoic acid and phenol are treated with calcium carbonate.
Assume the following: Methanoic acid, ethanoic acid, and phenol are present in solution. It is assumed that without any chemical adulteration that sufficient heat will cause these organic acids to convert to formaldehyde, methanol, and phenol gas/vapor. The lab objective is to prevent the formation of these organic vapors.
