when 2 or more compounds react chemically to form a new compound then it is called chemical reaction chemical reaction whereas the quantity and no. chemical elements presents in chemical compound is called the chemical composition
No, a physical change refers to a change in the form or appearance of a substance without any change in its chemical composition. If new substances are formed with different chemical properties, then a chemical change has occurred, not a physical change.
It refers to the energy changes that take place during a chemical reaction.
No, flammability is a chemical property, not a physical change. Flammability refers to a substance's ability to undergo combustion when exposed to a flame or spark, which involves a chemical reaction where new substances are formed.
Evidence of a chemical change refers to observable signs that a chemical reaction has occurred. This can include color change, formation of gas or precipitate, temperature change, or production of light. These changes indicate that the substances involved in the reaction have undergone a chemical transformation at the molecular level.

A reaction in a chemical reaction refers to the transformation of one or more substances into new substances with different properties. This process involves the breaking and formation of chemical bonds between atoms or molecules. Energy changes may also occur during a chemical reaction.
The molar relationship in chemistry is important because it helps determine the amount of substances involved in a chemical reaction. It refers to the ratio of the amounts of substances in a reaction based on their coefficients in the balanced chemical equation. This impacts chemical reactions by ensuring that the reactants are present in the correct proportions to produce the desired products. In essence, the molar relationship helps in predicting the outcome of a chemical reaction and understanding the stoichiometry involved.
Chemical changes are most often reffered to as chemical reactions and are represented by chemical equations.
In chemistry, equivalence refers to the equal amount of reacting substances involved in a chemical reaction. It is used to determine the amount of a substance by comparing the number of equivalents of different substances involved in the reaction. This helps in calculating the stoichiometry and quantities of reactants and products in a chemical reaction.
"Original substances" is a term that generally refers to the fundamental elements or components from which something is made. It can also refer to the primary materials used in the creation of a product or the foundational elements present in a system or process.
Reactants are the substances that participate in a chemical reaction and transform into products. They are the starting materials that are used up during the reaction, leading to the formation of new substances.
No. Presumably, if that were a subject of wide interest, it might be called carbon-dioxidation.Just plain old "oxidation" is the reaction of various substances with oxygen.
The reactants are on the left side of the equation, and the products are on the right side of the equation. The reactants are used up in a chemical reaction, and the products are the substances made by the reaction.
No, a physical change refers to a change in the form or appearance of a substance without any change in its chemical composition. If new substances are formed with different chemical properties, then a chemical change has occurred, not a physical change.
No, mass is not a chemical property. Mass is a physical property that refers to the amount of matter an object contains. Chemical properties, on the other hand, describe how a substance interacts with other substances in a chemical reaction.
It refers to the energy changes that take place during a chemical reaction.
