The answer to this is false.
Answer:
5.5 moles of sodium are produced
Explanation:
Given data:
Number of moles of hydrogen = 2.75 mol
Number of moles of Na produced = ?
Solution:
Chemical equation:
H₂ + 2NaCl → 2HCl + 2Na
Now we will compare the moles of hydrogen and sodium from balance chemical equation:
H₂ : Na
1 : 2
2.75 : 2/1×2.75 = 5.5 mol
Thus, 5.5 moles of sodium are produced.
If the magnetic lines of force intersected each other, then that would violate the laws of physics.
If the lines intersected, then at the point of
intersections there would be two directions of magnetic field force, and this cannot defy the laws of physics, so therefore it does not happen.
A good example of this would be if you had a
compass and you tried to use it to view the field direction. If you had two lines of force
intersecting, then the compass would have to
point in both directions, and that can't happen both theoretically and through observation.
An event like that would generate a monopole, which is an impossible, theoretical magnetic event.
These are called ocean or underwater trenches <span />
