A substance that is undergoing a chemical change is called a precipitate.
------------------------------------------Initial substances in a chemical reaction are called reactants.
Most substances undergo both changes - if the conditions are suitable.
When water is evaporated this is a physical change; when water react with sodium this is a chemical change.
Reactans is the right answer
i dont really know but bacon is awesome
water
Water is not a change of any sort. It is a substance. It can undergo physical and chemical changes.
The ability of a substance to undergo a chemical change is called the Chemical activity of a substance.
Yes.
No.
Yes, grinding is a physical change because the chemical composition of the substance does not change.
Copper sulfate is a substance, not a change. It can undergo physical and chemical changes.
Water is not a change of any sort. It is a substance. It can undergo physical and chemical changes.
Yes silicon can undergo physical and chemical changes.
All substances have distinct physical and chemical properties, and may undergo physical or chemical changes. Physical properties, such as hardness and boiling point, and physical changes, such as melting or freezing, do not involve a change in the composition of matter.
Chemical changes
Chemical properties describe how a substance will undergo chemical reactions and with what. Chemical changes are when one or more substances change to some other substance or substances.
The ability of a substance to undergo a chemical change is called the Chemical activity of a substance.
Chemical Reactivity :)
Yes.
Hg is not a change, it is an element. It can undergo changes, both physical and chemical.
matter
yes
