Scientific experiments are used to show what happens during a chemical reaction.
A chemical reaction is always written with the reactants (the things you mix together to do the reaction) on the left and the products (the stuff you get) on the right. In between is an arrow pointing right to indicate that the reactants react and become the products. Catalysts are sometimes listed above the arrow. And don't forget to balance the equation.
A chemical equation is the statement that uses chemical formulas to show the identities and relative amounts involved in a chemical reaction. It typically consists of reactants on the left side and products on the right side, separated by an arrow indicating the direction of the reaction.
The coefficients in a balanced chemical equation show the proportions of the reactants and products involved in a chemical reaction. Each coefficient represents the number of moles of each substance in the reaction.
When two chemicals bubble upon mixing, it typically indicates a chemical reaction is taking place. The formation of gas bubbles usually suggests a release of gas as a product of the reaction. This observable change is a common indicator of a chemical transformation.
If the acid test is positive for a mineral, the surface of the mineral may show signs of fizzing or bubbling due to a chemical reaction between the acid and the mineral. This reaction indicates that the mineral contains carbonate minerals like calcite or dolomite, which are reactive to acid.

a word equation, or a chemical equation
Chemical equations are used to represent reactions; they consist of chemical formulas for the reactants and products, along with arrows indicating the direction of the reaction. Other symbols may include (+) to separate reactants or products, and coefficients to represent the amount of molecules involved.
Chemical equations show the reactants involved in a chemical reaction, the products formed, and the stoichiometry or proportions in which they react. They provide a concise way to represent what happens in a chemical reaction.
You can show what happens in a chemical reaction by writing a balanced chemical equation that represents the reactants turning into products. Alternatively, you can use diagrams or drawings to illustrate the rearrangement of atoms and bonds during the reaction. Physical changes such as color changes, gas production, or temperature changes can also indicate a chemical reaction is occurring.
The arrow is an indication for the sense of reaction.
Symbols are used for the graphical representation of a chemical reaction.
Yes, a chemical equation shows the number of atoms of each element involved in a chemical reaction, including those gained, lost, or rearranged. The Law of Conservation of Mass states that mass is conserved in a chemical reaction, so the total number of atoms before and after the reaction must be the same.
When a compound produces.
The model that names all the chemicals in a reaction is called the chemical equation. It represents the reactants, products, and their respective symbols and formulas in a balanced format to show the chemical changes that occur during the reaction.
