Answer: varriable
Explanation:meaning one element, feature or factor able to change
mass MgCl₂ = mol x MM MgCl₂ = 0.05 x 95.211 g/mol = 4.76 g
mass Cl in MgCl₂ :
= (2 x AM Cl)/MM MgCl₂ x mass MgCl₂
= (2 x 35.5 g/mol)/95.211 g/mol x 4.76
= 3.55 g
% mass Cl in the mixture :
= (mass Cl / mass mixture) x 100%
= 3.55 / 9.8 x 100%
= 36.22%
Fog is a cloud that has its base at or near the ground.
The answer is letter D. Fog results when atmospheric water vapor condenses to
the extent that the new forms, water droplets or ice crystals, become visible. Saturation
of the air and sufficient condensation nuclei are ordinarily prerequisites for
the formation of fog. One of the great hazards associated with fog is a lack of
visibility.

Yes, it can happen.
If all the lower energy orbits are already filled with electrons, then it cannot happen since the lower orbitals will already be full, hence another electron will have to move.
However, if the lower energy orbits are not full (for instance if one excited electron goes back to its normal state), then it can happen.
