1) Any mixture of things typically has properties different than its components.
Examples:
a) Mixing pure elements to make a new chemical compound (e.g. Oxygen plus Carbon can combine to form CO2, which has properties different than either C or O. Carbon monoxide has different properties than CO2)
b) Mixing chemicals - e.g., Hydrochloric Acid (HCl) plus Sodium Hydroxide (NaOH, aka. Lye) combines to form water H2O and ordinary salt (NaCl)
c) Mixing metals forms an Alloy - e.g., Gold plus a little copper yields "red gold" which is harder than pure gold. Lead mixed with tin has a lower melting point than either metal.
d) Agregates - Even a mixure of sand and water to create wet sand has properties (behaviors) different than the separate components (try building a sand castle with dry sand). Mixing paint produces a new color of paint.
2) Phase change
Examples:
a) Water has different properties when frozem, liquid or steam
b) Solid CO2 (aka. Dry Ice) has different properties than gaseous CO2
3) Application of energy
Examples
a) Baking cake batter irreversibly changes the batter into something with different properties (yum!) Frying an egg causes an irreversible property change.
b) Roasting limestone to remove the water of hydration is a important step in making Calcium oxide for use in creating Cement
etc., etc., etc.
A chemical change produces a new substance with new properties. Some examples of chemical changes are the rusting of iron, baking bread, and the combustion of wood.
I am 99.9 percent sure it is a Chemical Because. a physical change does not change its identity and a chemical change does.
well when you boil starch it creates glucose
sry if it didnt help your question is worded funny
magnesium metal and hydrochloric acid
meelting cheese
physical change
When a substance changes but still retains its original properties, the change is called a physical change. If it didn't retain its original properties, then it went through a chemical change.
When different elements join to form a substance, it is called a chemical reaction or a chemical bonding process. During this process, atoms of different elements combine and rearrange to create a new substance with different properties. This can occur through various types of bonding such as ionic bonding, covalent bonding, or metallic bonding.
A substance that is formed from one type of atoms with a characteristic set of physical and chemical properties is called an element.
I'm pretty sure is is a Compound. A compound is a substance that is made up of more than on element. The properties of matter mostly depend on how atoms of different elements are combined in compounds.

It would be called a physical change, and would not be a chemical change at all. In order for a chemical change to occur, the original substances (reactants) must have different physical and chemical properties than the new substances (products).
