The majority of the carbon dioxide we exhale is produced in the cell during the process of respiration.

Explanation: Carbondioxide is a waste material which is produced in the process of respiration. In respiration, glucose molecules is broken down for releasing energy with the help of oxygen molecule which produces carbondioxide, water and energy in the form of ATP. Carbondioxide is removed through lungs and energy is used by the cell.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
