Answer:
The partial pressure of helium gas in a gaseous mixture of helium and hydrogen is the pressure that the helium would exert in the absence of the hydrogen. equal to the total pressure divided by helium's molar mass. O equal to the total pressure divided by the number of helium atoms present.

Answer:
As previously discussed, there is a connection between the number of protons in an element, the atomic number that distinguishes one element from another, and the number of electrons it has. In all electrically-neutral atoms, the number of electrons is the same as the number of protons. Each element, when electrically neutral, has a number of electrons equal to its atomic number.
Explanation:
<span>A colloid can be detected by using the Tyndall effect. The correct option among all the options that are given in the question is the second option. The other choices are incorrect and can be easily neglected. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.</span>
Answer:
See explanation
Explanation:
Now the element sodium has electronic configuration of [Ne]3s1
Florine has an electronic configuration of [He] 2p5
We know that in the formation of sodium flouride, sodium looses one electron to form Na^+ while F gains one electron to form F^-. So the electronic configuration of both Na^+ and F^- now become; 1s2 2s2 2p6
Answer:
1.VOLUME– The amount of space an object takes up. Basic Unit (SI Unit) for Solids – Cubic Meter, m3. LENGTH/DISTANCE – The measurement between two points.
2.one particle per cubic meter.
3.it means it is heavier
4.In a liquid the particles are still close together but a little further apart than in a solid.
5.In gases the particles are much further apart than in solids or liquids.
