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: A. Inverse relationship
Explanation: A plot illustrates that as x increases, y decreases - an inverse relationship.
Answer:
Ba(ClO₃)₂ → BaCl₂ + 3 O₂ <em>Descomposition. </em>
CaO + CO₂ → CaCO₃ <em>Combination. </em>
NaNO₂ + HCl → NaCl + HNO₂ <em>Double replacement. </em>
Mg + ZnSO₄ → MgSO₄ + Zn <em>Single replacement. </em>
Explanation:
A combination reaction is defined as a reaction in which two or more substances combine to form a single new substance.
A + B → AB
A descomposition reaction is defined as a reaction in which a compound breaks down into two or more simpler substances.
AB → A + B
A double replacement is a chemical reaction were the positive and negative ions of two ionic compounds exchange places to form two new compounds.
AB + CD → AD + CB
A single replacement is another type of reaction were one element replaces a similar element in a compound.
A + BC → AC + B
Thus, with this information it is possible to classify these reactions as:
Ba(ClO₃)₂ → BaCl₂ + 3 O₂ <em>Descomposition. </em>One single molecule breaks down into two or more molecules
CaO + CO₂ → CaCO₃ <em>Combination. </em>Two substances are combined to form one single molecule
NaNO₂ + HCl → NaCl + HNO₂ <em>Double replacement. </em>Na and H are exchange places to form two new compounds
Mg + ZnSO₄ → MgSO₄ + Zn <em>Single replacement. </em>Mg is replacing Zn.
I hope it helps!
