Reactant
Water is a reactant in photosythesis that is a liquid.
In this process, iron is the reactant undergoing oxidation, while oxygen is the reactant driving the oxidation reaction that causes iron to rust.
Glucose is taken from food.Oxygen is taken through air
This depends on the reaction involved.
Bromine does not react with air because it is not possible. It is a non reactant element.
The Limiting Reactant is the reactant that runs out first in a reaction.

everything comes from the air the air comes from the earth the earth comes from space

sulfur is a reactant

A. In the wood burning reaction, oxygen is the limiting reactant because there is a finite amount present in the air compared to the potentially unlimited amount of wood. The wood is the excess reactant since it is in excess of what the limited amount of oxygen can react with. B. In the reaction between sulfur in the air and silver flatware, the limiting reactant would be the sulfur since it is present in a limited amount compared to the silver flatware. The silver flatware is the excess reactant as it is in excess of what the limited amount of sulfur can react with.
In this process, iron is the reactant undergoing oxidation, while oxygen is the reactant driving the oxidation reaction that causes iron to rust.
