Part C Place the copper strips in test tubes 3 and 6. If the strips are too wide, you may bend them to fit them in the test tubes.
Place the magnesium strips in test tubes 1 and 4. If necessary, use the stirring rod to push the strips down until they're
entirely submerged.
Place the zinc strips in test tubes 2 and 5.
Record your observations of the appearance of the substances in the test tubes immediately after adding the metal
strips. Include any evidence of a chemical reaction. If there's no evidence of a reaction, write "no reaction."

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
