It is false because electrons have no mass.
I would pick the first option in the third option
Solids maintain their shape, whereas fluids do not because <span>the molecules in solids maintain a regular pattern and only vibrate, or move very slowly. The correct option among all the options that are given in the question is the last option or option "d". I hope the answer has come to your help.</span>
Answer:
0.54 moles of N2
Explanation:
First remember to find the volume in moles, 1 mole equals 22.4 liters.
So now use the dimensional analysis to show your work.
12 liters of N2 * 1 mol /22.4 liters of N2
Now calculate this. 12 * 1/22.4 or 12/ 22.4
12/22.4 = 0.535714286.
12 has two significant digits.
With that, The answer rounds to 0.54.
So that the final answer is 0.54 moles.
Hope it helped!
Answer : J. J. Thomson’s experiment disproved the theory that an atom is indivisible.
Explanation : Scientist J.J. Thomson did his experiment to prove the existence of electrons. He did the experiment using a cathode ray tube, in which a vacuum-sealed tube with a cathode and anode on one end was placed which created a beam of electrons that traveled towards the other end of the tube. This was the theory that proved that atoms consists of many subatomic particles namely electrons.
