<h3><u>Answer;</u></h3>
C. 3Mg + Al2O3 → 3MgO + 2Al
<h3><u>Explanation;</u></h3>
- <u><em>Single replacement reaction is a type of reaction which one reactant reacts with another and makes a product by replacing one element by another. </em></u>
- Mg (Magnesium) reacts with Al₂O₃ (Aluminium oxide) and produces MgO (Magnesium oxide) and Al (Aluminium) as products. Here Al is replaced by Mg. Reaction is
Mg + Al₂O₃ → MgO + Al
- To balance the reaction equation, both left and right hand sides should have same number of atoms in each element.
The balanced equation will be;
3Mg + Al2O3 → 3MgO + 2Al

Hard to find out do to chemical change
Answer:
The liquid which ever releases the greatest number of particles will have the lowest freezing point.
A) pure H2O
B) Aqueous FeI3 (0.030m) releases 4X's = 0.120 mol/litre ions
C) aqueous glucose (0.050m) releases 0.050 moles/litre glucoes
D) aqueous NaI (0.030m) releases 2X's = 0.060 mol/ litre ions
E) aqueous CoI2 (0.030m) releases 3 X's = 0.090 mol/litre ions
The answer is
B) Aqueous FeI3 (0.030m)
The answer is c 3 molecules
