Does running an electric current through copper change the identity of the substance?
No, running an electric current through copper does not change the identity of the substance. The process may cause the copper to undergo physical changes, such as heating or electrolysis, but the chemical composition of copper remains the same. The atoms of copper retain their identity throughout the process.
What properties refer to a substance's ability to undergo changes that alter its composition and identity?
Chemical properties refer to a substance's ability to undergo changes that alter its composition and identity. These changes often involve the breaking and forming of chemical bonds within the substance.
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 effect does an energy change have on the identity of a substance?
The identity of the substance reamain unchanged.
Is sugar changing to alcohol a physical or chemical change?
Anything changing to a substance with a different identity is undergoing a chemical change.

Is breaking a plate a chemical change?
No breaking a plate is a physical change. A chemical change is a change to a substance where its identity changes. When you break a plate you still have a plate not a new substance.
What is identity of a substance?
The identity of a substance (chemical compound) is defined by his chemical formula and molecular structure.
A physical property of a substance can only be observed if the substance changes into a different substance?
No, a physical property DOES NOT change the identity of a substance. That would be a chemical property which DOES change the identity.
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.
How can the identity of a substance be identified?
By density
What effect does an energy change have on the identity of a substance?
The identity of the substance reamain unchanged.
Is sugar changing to alcohol a physical or chemical change?
Anything changing to a substance with a different identity is undergoing a chemical change.
What is the diffeference between a physical and a chemical change?
A physical change is when a substance changes, but still keeps its identity. When a chemical change occurs, the substance changes its identity.
What is the term for a process that does not change the identity of a substance?
Many physical changes will not alter the identity. However, some physical changes, such as heating or cooling will result in phase changes and so the identity will be different. While ice and water are chemically the same, they are not identical forms of the substance.
What is a property of matter that can be identified without changing the identity of the substance.?
A property of matter that can be identified without changing the identity of the substance is its density. Density is a characteristic property that remains constant regardless of the amount of substance present.
