When a number is written in front of a molecule, that shows how many molecules of that substance are needed to balance the equation. For instance...
N2 + 3H2 -> 2NH3
which means to get two molecules of ammonia from nitrogen and hydrogen, we need one N2 molecule and three H2 molecules.
5 CO2 represents 5 molecules of carbon dioxide. Carbon dioxide is a compound composed of one carbon atom and two oxygen atoms.
This would appear in a chemical equation and denote that five molecules of carbon dioxide are required to complete the reaction.

What does Rx stand for in chemistry?
In chemistry, "Rx" stands for a prescription or a recipe. It is often used as a symbol to indicate that a compound or substance requires a prescription for use.
Give the 5 principal of the brnches in chemistry?
The five main branches of chemistry are organic chemistry, inorganic chemistry, physical chemistry, analytical chemistry, and biochemistry. Each branch focuses on different aspects of matter and the interactions between substances. Organic chemistry studies carbon-based compounds, inorganic chemistry focuses on non-carbon compounds, physical chemistry examines the physical properties and behavior of matter, analytical chemistry involves identifying and quantifying substances, and biochemistry studies chemical processes in living organisms.
What is the meaning of VD in chemistry?
In chemistry, VD can stand for either Van der Waals forces (weak intermolecular forces) or vapor deposition (a thin film deposition technique).
What are chemistry equations related to environmental chemistry?
H2o + co2 ----> o2 + carbohydrate
What is the chemistry sign for carbon dioxide?
The chemical formula (rather than 'sign') is CO2 for carbon dioxide.
What does 6CO2 stand for?
This is a Chemistry symbol. It is used in a balanced symbol equation and represents 6 carbon dioxide molecules. It is normally written as just CO2. But in this case, it should be part of a balanced symbol equation.
What does c for chemistry stand for?
carbon
What does the you symbol stand for in chemistry?
Uranium
What doesco2 stand for?

What does the symbol s stand for in chemistry?
Sulfur
What does the symbol Fr in chemistry stand for?
francium
What type of chemistry is involved in organic chemistry?
All carbon containing compounds except elemental C, CO and CO2 (and its simple derivatives)
5 products of chemistry?
The product is the result of a chemical reaction. NaCl, or table salt, is a product. HCl, hydrochloric acid, is another, and CO2, carbon dioxide, would be a third.
