Suppose you have 500.0 mL of a 0.25M Li2SO4 solution. How many lithium atoms are in this solution?
o 7.5 x 1022 lithium ions
O 1.5 x 1023 lithium ions
O 3.0 x 1023 lithium ions
O 0.50 lithium ions

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

did anyone actually do this? like if anyone has submitted this i rly need .

the answer is a for sure mark brainliest i had got this right on usatestprep
