Chemical
(Apex)
Chemical reactions involve the breaking and forming of chemical bonds in the original substances, resulting in a chemical change. Before a chemical reaction occurs, the original substances have specific chemical properties that undergo transformation during the reaction. The reactants interact to form new products with different chemical compositions.

These initial substances are the reactants.
A reaction has occurred when there are observable changes, such as a color change, the formation of a precipitate, the evolution of gas (bubbles), or a temperature change (exothermic or endothermic). Additionally, if the properties of the original substances change and new substances with different properties are produced, it indicates that a chemical reaction has taken place. Observing these signs can confirm the occurrence of a reaction.
The term is "products." In a chemical reaction, reactants react to form products. Products are the substances that are present after the reaction has taken place.

A chemical reaction is the change that takes place when different substances react with one another to form new substances. The substances that react in a chemical reaction are called the reactants and the new substances formed are called the products.
A chemical reaction is the process in which two or more substances interact to form new substances with different chemical properties. This process involves breaking and forming chemical bonds.
Yes, a chemical reaction is a process where two or more substances interact and chemically transform into new substances with different properties. This involves the breaking and forming of chemical bonds between atoms.

Observing these signs can confirm the occurrence of a reaction.
A chemical change can be determined when two substances are combined by observing if there is a color change, formation of a precipitate, evolution of gas, or change in temperature. Additionally, if the chemical properties of the substances change, such as their reactivity or toxicity, it indicates a chemical reaction has taken place.
Yes, a chemical reaction has likely taken place if there is a change in the chemical composition of the substances involved. This can be observed through the formation of new substances, changes in color, temperature, or the release of gas. These are all indicators that a chemical reaction has occurred.
