Nts) how many moles of oxygen gas are needed to react completely with 23.6 ml mg, which has a density of 1.74 g/ml? unbalanced equation: mg + o2 “yields”/ mgo 0.845 mol o2 1.12 mol o2 3.38 mol o2 20.5 mol o2

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
