1
A mole of helium (He) has the same number of atoms as a mole of titanium (Ti)
A mole of titanium (Ti) has more mass than a mole of helium (He).

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
