The products of the decomposition of calcium carbonate have different properties because a chemical change has occured in the reaction to form new substances.

CHEMICAL CHANGE:A chemical change is a type of change in which new products are formed. The bonds of the reactants are broken and rearranged to form entirely new substances. According to this question, calcium carbonate is a white mineral, which when heated produces carbon dioxide, CO2, and a white powder, CaO as follows: CaCO3 → CO2 + CaOThe products in this reaction are different in their properties from the reactants because a chemical change has caused new substances to be formed.

Answer from: adkinsryan72

A chemical change has occurred

Explanation:

Given reaction expression:

CaCO₃ → CaO + CO₂

The reaction is a decomposition reaction in which a compound is dissociated into simple products.

The reason why the products have different properties than the reactants is because a chemical change has occurred.

A chemical change is accompanied by the formation of a new productSuch new products have different properties compared to the compound that forms them. Therefore, the products and reactants are different chemically due to chemical change that has occurred.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
