When sodium is placed in water, the following chemical reaction occurs. 2Na(s) + 2H2O (l) —> 2NaOH (aq) + H2 (g). If a teacher uses a 0.500 gram sample of sodium metal for a demonstration with excess water, how many liters of hydrogen gas would be produced at STP?

look at the !

pleaze mark brainliest!

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

answer: i dont know the answer but this might
