Does mass of compounds change due to exothermic/endothermic chemical reactions?

Mass is a measure of the amount of matter in an object. It is commonly measured in grams (g) or kilograms (kg) using a balance or scale.
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. This means that the total mass of the reactants must equal the total mass of the products.
A chemical reaction is a process in which one or more substances are transformed into new substances with different properties. This is often accompanied by the release or absorption of energy.
A chemical equation is balanced by making sure that the number of atoms of each element is the same on both sides of the equation. This is achieved by adding coefficients in front of the chemical formulas.
The rate of a chemical reaction can be affected by factors such as temperature, concentration of reactants, surface area, and the presence of a catalyst. These factors can either speed up or slow down the reaction.
