2 what would be the volume in liters of an ideal gas, if a 0.111 mole sample of the gas had a temperature of 1130 degrees celsius at a pressure of 5.45 atmospheres? (the ideal gas constant is 0.0821 l•atm/mol•k.)
0.43 liters
1.43 liters
1.89 liters
2.35 liters
3 an increase in temperature will increase gas particle collisions with the walls of the container.
true
false

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
