Is powdering of sugar a chemical change?
no because chemical change means formation of a new substance but in powdering no new substance is formed
Is heating a chemical or physical change?
Heating a substance can result in either a physical change or a chemical change. A physical change does not alter the substance's composition, such as melting or boiling, while a chemical change leads to the formation of new substances with different properties, such as burning or baking.
Must a new substance be formed when you observe a chemical propery?
The formation of a new substance is the criterion for a chemical change. You can't have a chemical change without the formation of at least one new substance. As you can't observe a chemical property without setting a chemical change in motion, the answer to your question is yes.
When a substance changes into a different substance a what change has occurred?
Chemical change.
When two substances are mixed they might form a new substance What would indicate that a new substance has been formed?
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence - formation of new compounds
A chemical change is a change in the of a substance....?
A chemical change is a change in the composition or structure of a substance, resulting in the formation of new substances with different properties. This type of change is usually irreversible and involves the breaking and forming of chemical bonds.
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.
What describes a change that occurs when one substance reacts with another substance?
A chemical reaction occurs when one substance reacts with another, resulting in the formation of new products with different properties. This change involves the breaking of existing bonds in the reactants and the formation of new bonds to create the products.
What evidence indicates the formation of a new substance?
Some indicators of a chemical reaction are:- change of color- change of odor- release of a gas- change of the temperature- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion- possible chemiluminescence -formation of new compounds

What happens to the composition of a substance during a chemical change?
Atoms are rearranged, heat may be given off, changes in color and odor might occur, or a gas or precipice may be formed. The composition is changed, and the above are signs of a chemical change.
What type of change produces a new substance?
A chemical change produces a new substance. This occurs when the original substances undergo a chemical reaction, resulting in the formation of new substances with different chemical properties.
