The representation is CO2(g).
The large number in the chemical equation represents the coefficient, which indicates the ratio of each molecule or formula unit involved in the reaction. It helps balance the equation to ensure that the conservation of mass is maintained.
In a chemical equation, each element has a symbol (in the periodic table in the elements). You use those symbols to create a chemical equation. For example, water is H2O. "H" represents Hydrogen, "O" represents Oxygen and the 2 means that there are two oxygen particles for each oxygen particle. Together, this creates one water molecule.
The chemical symbol (not equation) of hydrogen is H; the diatomic molecule is H2.
A substance or molecule that forms in a chemical equation is a product. Products are the result of a chemical reaction between reactants, and they are found on the right side of a chemical equation.
If you think to carbon dioxide the molecule CO2 has 1 carbon atom.
A chemical formula is the representation of a molecule of a chemical compound; all the atoms from the molecule of this compound need to be represented in the formula.
To let you know what kind of atoms (and how many) make up certain molecules. For example H2O is a chemical equation for a molecule of water. It shows us that there are 2 atoms of Hydrogen and 1 atom of Oxygen in a water molecule. Hope this help! -Sixth Grade Science Teacher
The amount of each molecule
The chemical equation for the reaction between a silicon atom and a chlorine molecule is: Si + Cl2 → SiCl4
The subscript denotes how much of that atom is in the molecule.
The cell needs oxygen molecule (O2) in the chemical equation of respiration as it acts as the final electron acceptor in the electron transport chain to produce ATP.
