Answer:
smallest unit element are made of
Answer:
I suppose that oxygen bonds with the carbon and escape the molten metal in a gaseous form. Not sure about this but i tried to help.
Explanation:
B.) Weight.
Weight is the combination of gravity on mass, thus it produces a force. (gravity is the force)
In Thomson's cathode-ray experiment,<span>He sucked all of the air out of the tube, so only the ray was inside. He then concluded that the ray was negatively charged because the ray came from the cathode ray and went to the positively charged anode ray, so the cathode had to be negative or else it would have deflected away from the anode.
Hope this helped ! Let me know if you need more information ! :)</span>
The molar mass and the mass of the substance give the moles of the substance. The 10-gram sample of neon (Ne) has the fewest atoms. Thus, option b is correct.
<h3>What are moles?</h3>
Moles of the substance are the ratio of the molar mass and the mass of the substance. The moles of each atom with respect to the Avagadro's number (Nₐ) is given as,
Moles = mass ÷ molar mass
- Moles of carbon (C) = 10 ÷ 12
= 0.83 Nₐ atoms
- Moles of neon (Ne) = 10 ÷ 20
= 0.5 Nₐ atoms
- Moles of fluorine (F) = 10 ÷ 19
= 0.52 Nₐ atoms
- Moles of nitrogen (N) = 10 ÷ 14
= 0.7 Nₐ atoms
- Moles of oxygen (O) = 10 ÷ 16
= 0.63 Nₐ atoms
Therefore, option b. 10 gm neon has the fewest atoms.
