Answer:
Turgor pressure in plants. Turgor pressure within cells is regulated by osmosis and this also causes the cell wall to expand during growth.

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.
Answer:
Mg(s) + 2NaF (aq) —> MgF₂ (aq) + 2Na(s)
Explanation:
Magnesium => Mg
Sodium fluoride => NaF
Magnesium fluoride => MgF₂
Sodium metal => Na
The equation can be written as:
Mg + NaF —> MgF₂ + Na
Thus, the above equation can be balance as illustrated below:
Mg + NaF —> MgF₂ + Na
There are 2 atoms of F on the right side and 1 atom on the left side. It can be balance by writing 2 before NaF as shown below:
Mg + 2NaF —> MgF₂ + Na
There are 2 atoms of Na on the left side and 1 atom on the right side. It can be balance by writing 2 before Na as shown below:
Mg + 2NaF —> MgF₂ + 2Na
Mg(s) + 2NaF (aq) —> MgF₂ (aq) + 2Na(s)
Now, the equation is balanced.
