Is it true when a physical change that takes new substances are formed?
No, in a physical change, no new substances are formed. The change only affects the physical appearance or state of the matter, such as size, shape, or phase, but the chemical composition remains the same.
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.
What are facts about physical and chemical change?
Chemical changes take place on the molecular level
What is a substance when formed two or more substances are combined and a chemical change takes place?
a compound
Write 3 differences between chemical and physical change?
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
Is the change that takes place when two or more substances interact to form new substances.?
A chemical reaction is the change that takes place when different substances react with one another to form new substances. The substances that react in a chemical reaction are called the reactants and the new substances formed are called the products.
Is adding HCl to Mg physical change?
No, adding hydrochloric acid (HCl) to magnesium (Mg) and observing the resulting chemical reaction is a chemical change, not a physical change. The reaction produces hydrogen gas and magnesium chloride, with new substances formed.
Differences between chemical and physical properties?
In a physical change of matter, no new substances are formed. However, physical properties such as size, shape, color, or phase may change. Dissolving, melting, evaporating and grinding are examples of physical change.As a result of chemical change, one or more new substances with new and different properties are formed. The new substances are different from the original substance. Burning and the rusting of iron are examples of chemical change.
Is heating sand to its melting point a chemical or physical change?
Heating is purely physical, though at higher temperatures also some or many chemical reactions might take place: e.g. decomposition (break down) of mineral carbonates into oxides and carbon dioxide.
Is thousand island and mayo mixed together physical or chemical change?
Mixing thousand island dressing and mayonnaise together is a physical change because no new substances are formed. The molecules in the two condiments simply mix together physically without any chemical reactions taking place.

I am looking into it and let you know as soon as I decide.
A substance formed when two or more other substances are combined and a chemical change takes place?
A compound is formed when two or more other substances are combined and a chemical change takes place. Pure water would be an example of a compound.
