I believe the answer is false
Explanation:
The given compound is:
AlCl₃
- ionic formula - it is a combination between a metal and non - metal with an electronegativity difference greater than 0.7
- 3 chlorine atoms - from the compound, we see that the compound is made up of 1 aluminum atom and 3 chlorine atoms.
- Aluminum is the cation
- Chlorine is the anion
A cation is the positively charge specie and the anion is the negatively charged one.
Al³⁺ + 3Cl⁻ → AlCl₃

10.045830 × atoms of scandium are in 75.0 g.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Given data:
Mass of scandium = 7
Molar mass of scandium=44.96 g/mol
Moles =1.66814 moles
Number of atom= 1.66814 moles x 6.02214076 ×
Hence, 10.045830 × atoms of scandium are in 75.0 g.
