Answer:
The electron geometry of AlCl₃ is triangular planar.
Explanation:
The aluminium atom has 3 electrons in its valence shell. The chlorine atom has 7 electrons in its valence shell. Therefore, each chlorine atom can pair one electron with one electron of the aluminium atom, forming single bonds. The image attached shows how the Cl atoms are arranged around the Al atom.
All the single bonds are in the same plane and the Cl atoms form a triangular shape. This is why the geometry of the AlCl₃ molecule is triangular planar.
Answer:
1.12M
Explanation:
Given parameters:
Volume of solution = 2.5L
Mass of Calcium phosphate = 600g
Unknown:
Concentration = ?
Solution:
Concentration is the number of moles of solute in a particular solution.
Now, we find the number of moles of the calcium phosphate from the given mass;
Formula of calcium phosphate = Ca₃PO₄
molar mass = 3(40) + 31 + 4(16) = 215g/mol
Number of moles of Ca₃PO₄ = = 2.79moles
Now;
Concentration =
Concentration = = 1.12M
