C is not a property of metals
B) magnetic pole.
Explanation:
The magnetic pole is the area around a magnet where magnetic effect is the strongest.
Around a magnet, there is a force field in which the effect of magnet is felt.
- The strongest intensity of the force is felt at the pole.
- The magnetic force field leaves the north pole and enters through the south.
- Magnetic materials and magnets are drawn closer to the poles.
- The earth also like a magnet.
- The magnetic north is located close to the geographic north pole and also for the south pole.

Two compound samples are composed of the same elements but in different proportion, it means the two samples are two different compounds.
Because there are many compound which consist of same elements. for example water and hydrogen peroxide are two different compounds but these compounds consist if same elements, hydrogen and oxygen;
H₂O consist of hydrogen and oxygen and it is water
H₂O₂ also consist of hydrogen and oxygen but it is hydrogen peroxide
So, both are different compounds

All atoms except H and O are balanced.
The oxidation number of Cl changes from 7 to 3. The change in the oxidation number is 4.
The oxidation number of O changes from -1 to 0. The change in oxidation number per O atom is 1.
Total change in the oxidation number for 2 oxygen atoms is 2.
To balance the increase in oxidation number with decrease in the oxidation number, multiply H

The oxygen atoms are already balanced.
This is the balanced chemical equation
