Answer: 48800g
Explanation:
Using the mathematical relation : Moles = Mass / Molar Mass
Moles = 488
Molar mass of CaCO3 = 40 + 12 + (16 x 3) = 100g/mol
Therefore
488 = mass / 100 = 48800g
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

Explanation:
The general trend as you go to the right in any one period is for the size to decrease.
The general trend is that the size increases as you go down a Group.
The general trend as you go from the bottom left to the top right is a decrease in size.
Ionization energy increases as we move to the right in a period.
It decreases as we move down a group.
Going from the bottom left to top right - the ionization increases.
