Acid and base.
It is obtained from air. Oxygen is not is not produced in dark reaction but in light reaction
Oxygen is a nonmetal.
The product of nonmetal oxide water is oxyacid.
Oxygen is nonmetal because since oxygen isn't visable it's not solid so oxygen is nonmetal.
Rusting is an oxydation reaction; in this case oxygen (a nonmetal) react with iron (a metal). Oxygen is a very reactive chemical element.
Reaction between a metal oxide and a nonmetal oxide to produce a salt containing at least three elements is a synthesis reaction. The salt almost always contains at least one monatomic metal cation and at least one polyatomic anion that contains all of the elements of the reacted nonmetal oxide plus the oxygen atoms from the metal oxide. This type of anion is called an "oxyanion" or the "anion of an oxyacid."
Rusting is an oxydation reaction; in this case oxygen (a nonmetal) react with iron (a metal). Oxygen is a very reactive chemical element.
A rapid reaction between oxygen and a fuel is called combustion.
Respiration involves reaction between oxygen and glucose. This is what forms carbon dioxide.
Lead Monoxide is a covalent bond because lead is a metal and oxygen is a nonmetal. A covalent bond is between a metal (like lead) and a nonmetal (like oxygen).
Reaction between a metal oxide and a nonmetal oxide to produce a salt containing at least three elements is a synthesis reaction. The salt almost always contains at least one monatomic metal cation and at least one polyatomic anion that contains all of the elements of the reacted nonmetal oxide plus the oxygen atoms from the metal oxide. This type of anion is called an "oxyanion" or the "anion of an oxyacid."
The chemical energy needed to drive all the chemical processes of the human body is obtained by an oxidation reaction that requires oxygen.
