Answer: The expression [tex]CaCO_{3}\rightarrow CaO+CO_{2}[/tex] is an example of chemical reaction.
Explanation:
Given expression,
[tex]CaCO_{3}\rightarrow CaO+CO_{2}[/tex]
This is the chemical equation.
We know that,
In this equation, [tex]CaCO_{3}[/tex] is the reactant and [tex]CaO+CO_{2}[/tex] is the product.
The substance initially present in the chemical reaction is called reactant and the substance formed by the reaction is called product.
Hence, The expression [tex]CaCO_{3}\rightarrow CaO+CO_{2}[/tex] is an example of chemical reaction.
By definition, the expression CaCO₃ → CaO + CO₂ is an example of a chemical equation.
Definition of chemical reaction
A chemical reaction is any process in which at least the atoms, molecules, or ions of one substance are changed into atoms, molecules, or ions of another chemical substance.
Definition of chemical equation
A chemical equation is a symbolic description used to describe the identities and relative quantities of the reactants and products involved in a chemical reaction.
The information contained in the chemical equation allows us to determine the substances that are transformed or modified in a reaction, called reactants or reagents, and the new substances that originate in a chemical reaction, called products.
In order to represent what happens in a chemical reaction by means of an equation, it must comply with the Law of conservation of matter and with the Law of conservation of energy. That is, the equation must indicate that the number of atoms of the reactants and products is equal on both sides of the reaction and that the charges are also equal. In other words, you must have a balanced equation.
Summary
Finally, the expression CaCO₃ → CaO + CO₂ is an example of a chemical equation.
