What else can I help you with?
New substances are always formed when matter undergoes what?
chemical change.
What is always a characteristic of a chemical change but not always a characteristic of a physical change?
When a chemical change takes place, the chemical structure of particles involved changes (i.e. one or more new substances are formed). In a physical change, the physical state of the particles involved changes (e.g. a solid melts and becomes a liquid). The chemical structure of the particles does not change, and no new substance is formed.
In a chemical change what substance is formed?
The substance formed in a chemical change is called Product.
What is a fact about chemical change and physical change?
chemical change is when during a chemical reaction a new substance will be formed while in physical change no new substances are formed
New substances are always formed when matter undergoes?
a chemical reaction, where bonds between atoms are broken and new bonds are formed resulting in the creation of new substances with different chemical properties.
When do you say that a change is chemical?
A chemical change has occurred when a new substance is formed. Characteristics of this include a color change, precipitate is formed or it bubbles meaning a gas has formed.
Is Heating potassium chlorate a chemical or physical change?

How does the name of an atom change when a compound is formed?
This is a chemical change, a chemical reaction.
What always results in a chemical reaction?
A chemical reaction always occurs when the bonds between atoms in one or more substances are broken or formed, leading to the creation of new substances with different chemical properties. This process involves the rearrangement of atoms and the release or absorption of energy.
A change where compounds are formed or deconposed is a?
chemical change
Could the same substance be formed in a chemical change?
No, in a chemical change new substances are formed with different chemical properties compared to the original substances.
What is formed in a chemical change?
a bond
