A single atom of carbon is joined to a hydrogen atom. How many double bonds can the carbon still form?

One carbon atom forms four covalent bonds with four hydrogen atoms by sharing a pair of electrons between itself and each hydrogen (H) atom.

Explanation:

b, acidosis

acidosis is when the human body attempts to return the bloods ph levels back to normal when the blood is acidic

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
