1 Live in warm, moist environments, including swimming pools and showers.  Can invade your skin through cuts so tiny you can't even see them or through a small separation between your nail and nail bed.
Methane is a hydrocarbon (CH4. Therefore it is COVALENTLY bonded because of the bonds between carbon (non-metal) and hydrogen (non-metal). Ionic compounds only apply to those made of metals and non-metals.ethane is a hydrocarbon (CH4.

It is ionic. Ionic bonds are formed between a metal and a nonmetal. In this case, the metal is Sodium (Na) and the nonmetal is Chlorine (Cl). Also important, ionic bonds are formed between cations and anions. The cation is Sodium and the anion is Chlorine.
