representative particles?

silver

carbon

nitrogen

cesium iodide
@sweetburger

Answer 1

Hint: 1 mole of every gas occupies 22.4L

Answer 2

I have no idea still

Answer 3

This is just one of those things:

1 mole of every gas ( doesn't matter what gas it is) occupies 22.4L so 1 mole has 6.02x10^23 particles in it., at standard temperature and pressure, STP

STP means 1 atm 298K

Answer 4

i know its not d

Answer 5

why?

Answer 6

I just know but im not sure about abc

Answer 7

it must be a gas at room temperature

Answer 8

so which one of those compounds would be a gas at room-temperature?

Answer 9

not silver

Answer 10

or carbon

Answer 11

so its nitrogen? @greatlife44

Answer 12

so try to explain yourself here you said that it's not silver, why wouldn't it be silver or carbon?

Answer 13

they are bith solids at room temp

Answer 14

good

Answer 15

so nitrogen is right?

Answer 16

\[N_{2} \] = gas at room temperature

Answer 17

@18jonea this is a property of all compounds that are gases under the conditions of STP which are 298K and 1 atm 1 mole of every gas will occupy 22.4L

Answer 18

ok thanks for the help

Answer 19

No problem
