the elements contained in the reactants are equal to those in the products.
e.g.
4H +O2 -> 2H20
Stoichimetry
When water freezes, it will go through an exothermic reaction, which is a chemical reaction that releases energy in the form of light or heat. It is expressed in a chemical equation as: reactants --> products + energy
Mass can neither be created or destroyed in a chemical reaction, so there is a requirement that the mass of all the reactants MUST equal that of the products.
The law of conservation of matter/mass applies to chemical reactions. This is why chemical equations must be balanced. The matter that goes into a chemical reaction is present in the products of the reaction, but the atoms have been rearranged to form products with new and unique properties different from the reactants.
Two products are formed; one is a precipitate.
In Chemistry, this is the known as the Law of Conservation of Matter. While the moles of individual substances may change, the number of atoms of reactants is the same as the number of atoms of products.
the coefficients of a balanced reaction
This representation is a chemical equation.
In a chemical equation the reactants appears to be on the left side. On the left you have the reactants and to the right you have the products.
No. The reactants are written on the left of the arrow.
reactants ---> products
The reactants must be balanced correctly with reactants.
Reactants -> Products
Reactants and products
the moles of the reactants and products
reactants -----> products is correct
In a correctly written chemical equation, reactants are the substances to the left of the arrow, and products are the substances to the right of the arrow. The reactants are what you have before the reaction starts, and the products are what you have when the reaction is over.
Products are what the reactants convert to after a reaction is complete. The products are traditionally shown on the right hand side of a chemical equation.
