During a chemical change the form of a substance is altered but not its identity true or false?
The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.
Is oxidizing a physical or chemical change?
Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.
Is zinc dissolving in vinegar to form a rusty substance on an iron nail a physical or chemical change?
chemical change
Is corrosion of aluminium metal a physical change or a chemical change?
It is a chemical change. Through corrosion, a chemical reaction has taken place.
Is it a physical or chemical change when a substance changes form but it remains the same substance?
it would be physical change because physical change is when the substance stays the same
How does matter chemically change?
The chemical changes take place on moleculer space. A chemical change form (or) produce a new substance.
What is a change that alters the form or appearance of a substance but does not make it into other substance?
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
When a substance changes into a diffrent substance what change has occurred?

What is the definition chemical change?
Chemical ChangesAs opposed to a physical change, chemical changes are present when the substance undergoes a chemical reaction and produces a new substance. A chemical change is a chemical reaction that will always take place for there to be a chemical change. Signs that a reaction is taking place: Formation of gases (bubbles), Color change, production of heat or light, and the formation of a solid. a change in composition and characteristics of matter.new substance maybe formed.original substance and form may be lost.new color and shapeExamplesFermentationPhotosynthesisRusting nailSpoiling milkDigesting food
What kind of change form new substance?
Apex: A Chemical Change.
Why is a state change not a chemical change?
You're only changing the form of the substance, not the chemical compounds in it.
When a substance changes into a different substance a what change has occurred?
Chemical change.
During a chemical change the form of a substance is altered but not its identity true or false?
The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.
Is it a chemical reaction when a substance changes its form?
The change of form in not a chemical process; it is only a physical change, the molecules remain unchanged.
Is oxidizing a physical or chemical change?
Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.
Is a change that produces a new substance is a chemical change?
False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.
Is zinc dissolving in vinegar to form a rusty substance on an iron nail a physical or chemical change?
