By state of matter I assume you mean solid, liquid, gas, in which case the answer would be C.
the behaviour of molecules:
- in a solid is low energy with limited activity where molecules only vibrate, cannot mould to shape of container
- in a liquid is with moderate energy, with molecules flowing over the top of one another, and thus can mould to the shape of the container
- in a gas is high energy with much activity, molecules "fly" around the container they are in and can be compressed
Answer:
In 1 mol of anything, you have 6.02×10²³ particles, so 1 mol of F₂ contains 6.02×10²³ molecules.
<span>Use Root mean square speed formula:
vrms = Sqrt (3RT/M)
T - temperature in K = 273K - 21CÎż = 252K
R- molar gas constant = 8.31J/Kmol
M - molar mass of a molecule
MN2 = 14x2 = 28 g/mol
MO2 = 16 x 2 = 32 g/mol
MO3 = 16 x 3 = 48 g/mol
Having all info now, you can calculate root mean square speed,vrms ,
for every molecule by using the aboveequasion and only changing M value.</span>
