If 20. milliliters of a 1.0 M solution of HCl is exactly neutralized by 40. In a redox reaction, the reducing agent will lose electrons and be reduced. Gain electrons and be oxidized. A hydrocarbon molecule is considered to be saturated if the molecule contains single covalent bonds, only. In a chemical reaction, as a species is oxidized, its oxidation number decreases.
Increases Remains the same.
As a chemical bond forms between two hydrogen atoms in a system, energy is released , and the stability of the system decreases. Increases Remains the same.
