What Is a Chemical Change?
A chemical change is one of the types of changes an object or a mixture of substances can undergo, which results in a total alteration of its physical and chemical properties.
How to Discern a Chemical Change
It is very important to know how to distinguish and discern between physical and chemical change, as some chemical outputs are very harmful to the human body and physiology. One can observe various signs and indicators that will help the person identify whether or not a chemical change has occurred.
Step 1: Observe any Changes in the Object’s Physical Properties
Begin by conducting a small observation of the compound or mixture and check if there are any changes in the object’s physical properties. Most occurrences of chemical change will include a change in the compound or object’s physical property.
Step 2: Determine if the Change is Reversible
When a physical change occurs it is often reversible when the proper amount of energy is exerted on the compound or object. A chemical change is irreversible, therefore you must determine if the object’s change is reversible or irreversible.
Step 3: Check if Heat or Light is Present
Some chemical changes give off heat or light after the chemical reaction happens. You must check if heat or light is present as it is a large sign of chemical change in the substance, object, or mixture. (See endothermic reaction and exothermic reaction)
Step 4: Determine whether the Compound is Emitting Gas
Some chemical reactions emit gas, which results in a successful chemical change. Determine if the outcome is emitting gas or any form of smoke, but be careful not to inhale said gas.
FAQs
Chemical change vs. physical change; what is the main difference between both types of changes?
A chemical change is an observable change of a specific compound or object, which results in an alteration of the chemical and physical properties of the compound or object. This type of change can only occur when the chemical and molecular structure of the compound is altered. A physical change is an observable change of a specific compound or object, which results in an alteration or change of the compound or object’s physical properties. This type of change is reversible, unlike chemical change.
What are chemical reactions and how are they related to chemical change?
A chemical reaction is an outcome that occurs when someone mixes two or more miscible substances in a mixture. This reaction causes chemical change to occur and emits heat in the form of thermal energy and chemical energy. Not only that, but chemical reactions have a lot of uses, one of which is their ability to create nuclear energy through nuclear fission.
What are the indicators or elements that constitute a chemical change?
There are many ways one can do to observe a chemical change in a specific mixture or substance. Most of these indicators or elements are related to the physical and chemical properties of the mixture or substance. These indicators can range from a change in smell, change of color, creation of precipitation around the vessel, formation of heat, and the creation of light.
A chemical change is a type of change that occurs or happens when a molecular makeup of a substance changes. Sometimes chemical changes are very dangerous as some compounds have drastic effects on the human body. Therefore it is important to know when a chemical change occurs in one’s surroundings.
