C. a change of state. It can be a physical or a chemical state of change.
The position is the strength of the magnetic field strongest is is the place where the magnetic field leaves, being point A.
<h3>What generates a magnetic field?</h3>
When an electrically charged particle moves, it creates a magnetic field. According to the laws of electromagnetism, this magnetic field originates from the variation of the electric field strength.
In the region of the poles we see that the lines of magnetic induction are closer to each other, therefore, we consider that close to the poles the magnetic field is more intense.

Element X is sodium.
If there is one more shell of electrons, then this means it is one period below.
Since there is one less valence electron, it is one group to the left.
Answer:
Sc(OH)₃ = 96 g/mol
Explanation:
Gram formula mass:
Gram formula mass is the atomic mass of one mole of any substance.
It can be calculated by adding the mass of each atoms present in substance.
Sc(OH)₃:
Atomic mass of Sc = 45 amu
Atomic mas of O = 16 amu
There are three atoms of O = 16 ×3
Atomic mas of H = 1 amu
There are three atoms of H = 1 ×3
Gram formula mass of Sc(OH)₃:
Sc(OH)₃ = 45 ×1 + 16 ×3 + 1 ×3
Sc(OH)₃ = 96 g/mol
