A change in matter that results in the formation of a new substance with different properties?
I assume you're asking for clarification about chemical reactions.
I'm sure you know that individual atoms are not changed (short of nuclear or quantum effects, which are far deeper than Chemists take things). A substance is made up of particles consisting of a specific arrangement of these atoms, called molecules. A chemical reaction is a rearrangement of the atoms, creating a different collection of molecules. This alternate arrangement will have different properties than the original molecules.
For example, when burning sugar, there is a reaction between the sugar molecules (consisting of carbon, hydrogen and oxygen) and the oxygen molecules in the air. This reaction rearranges these molecules to create carbon dioxide and water (more correctly, water vapor, since the flame is hot). The reaction takes all of the carbon from the sugar and some of the oxygen (from both sources) to create carbon dioxide and all of the hydrogen from the sugar and the rest of the oxygen to create water molecules. The properties of these common molecules are well known and differ from each other significantly.
What else can I help you with?
What do all compounds share?
All compounds are made up of two or more different elements chemically bonded together. This formation results in a new substance with unique properties distinct from the properties of the individual elements.
A substance is permanently altered by?
A substance is permanently altered by undergoing a chemical reaction that changes its molecular structure, composition, or properties. This alteration is often irreversible and results in the formation of new substances with different characteristics than the original substance.
A substance is giving off heat light and smoke Most likely the type of change that is occurring is?
Chemical change, as it involves a chemical reaction that results in the formation of new substances with different properties.
How do you know if a chemical change has occurred versus a physical one?
A chemical change results in the formation of new substances with different chemical properties, such as changes in color, odor, or the formation of gas or precipitate. A physical change, on the other hand, only affects the physical state of a substance, without changing its chemical composition.
What is the most important quiestion to ask to determine whether a change is physical or chemical?
The most important question to ask is whether the change results in a new substance being formed. Physical changes involve a change in appearance, state, or size of a substance without forming a new substance. Chemical changes involve a reaction that results in the formation of new substances with different chemical properties.

Can the substance that take part in a chemical reaction keep their properties?
In a chemical reaction, the substances involved typically undergo a change in their properties as bonds are broken and new bonds are formed. This results in the formation of new substances with different properties than the original substances.

Can matter undergo changes in both its physical and its chemical properties?
Yes, matter can undergo changes in both its physical and chemical properties. Physical properties changes do not alter the composition of the substance, such as changing state from solid to liquid. Chemical properties changes involve a chemical reaction that results in the formation of new substances with different chemical compositions.

Physical changes involve a change in appearance, state, or size of a substance without forming a new substance. Chemical changes involve a reaction that results in the formation of new substances with different chemical properties.
How do the properties of a new substance compare with the properties of the original substances after a chemical change takes place?
After a chemical change, the new substance will have different properties compared to the original substances. The chemical reaction typically results in the formation of new bonds and rearrangement of atoms, leading to changes in physical and chemical properties such as color, smell, temperature, and composition. The new substance may have different reactivity, boiling point, melting point, and solubility compared to the original substances.
What result in a new substance formed?
A chemical reaction results in the formation of a new substance through the rearrangement of atoms and bonds between them. This can involve breaking existing chemical bonds and forming new ones to create a structurally different substance with unique properties.
What characteristic gives a substance the ability to undergo a change that results in a new substance?
Chemical reactivity is the characteristic that allows a substance to undergo a change that results in a new substance. This involves the rearrangement of atoms and the formation of new chemical bonds.
Is the formation of salt a chemical or physical change?
The formation of salt is a chemical change because it involves the rearrangement of atoms and the formation of new chemical bonds between sodium and chloride ions. This results in a new substance with different properties from the original sodium and chloride ions.
What does a change in a chemical properties of a substance result in?
A chemical reaction (change) results in a change in chemical properties.
