Answer:

The correct answer is:

'He did not multiply the chlorine and oxygen atoms by the coefficient 4'.

Explanation:

Number of atoms in $4 Ca(ClO_3)_2$

The 4 in front of molecular formula of calcium chlorate is its coefficient . it tells us about the molecules or moles of compound.

Number of calcium in 1 molecule of calcium chlorate = 1

Calcium atoms in 4 molecule of calcium chlorate = 1 × 4 = 4

Number of calcium in 1 molecule of calcium chlorate = 2

Chlorine atoms in 4 molecule of calcium chlorate = 2 × 4 = 8

Number of oxygen in 1 molecule of calcium chlorate = 3 × 2 = 6

Oxygen atoms in 4 molecule of calcium chlorate = 6 × 4 = 24

So, number of atoms of different elements calculated by Carl was wrong as he didn't multiplied the coefficient 4 with chlorine and oxygen atoms.

Answer:

Ferromagnetism, physical phenomenon in which certain electrically uncharged materials strongly attract others. Two materials found in nature, lodestone (or magnetite, an oxide of iron, Fe3O4) and iron, have the ability to acquire such attractive powers, and they are often called natural ferromagnets.
