If the aluminum bubbles it will be a chemical change.
physical. You can change it into another can.
Burning anything, including aluminum, is a chemical change.
Aluminum or anything else melting is a physical change.
Aluminum forms a +3 ion, and hydroxide's formula is OH-, so the formula for aluminum hydroxide would be: Al(OH)3
Aluminum reacts with oxygen to produce aluminum oxide.4Al(s) + 3O2(g) → 2Al2O3(s)
Aluminum bending is a physical change. This is because the aluminum is still the same aluminum as it was before just in a different shape.
It is a chemical change, because a new substance is created, and you cannot reverse it back to the way it was.
It's a chemical change. The aluminum foil is rusting, which cannot be undone, meaning that this is a chemical change, not a physical. Physical changes can be reversed.
FALSE
Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
Be careful with your terminology.Mixing aluminum and hydrochloric acid is not a chemical change.The resulting reaction, however, is a chemical change.
Aluminum bending is a physical change. This is because the aluminum is still the same aluminum as it was before just in a different shape.

This is a chemical reaction; synthesis of aluminium chloride.
FALSE
Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
All chemical reactions are chemical changes.
