Answer: Redox Reaction
Explanation:
Redox reaction is the key chemical events in an oxidation-reduction also called Redox. It is the net movement of electrons from one reactants to another
If the glasses and glove were wrong then I would chose the fire extinguisher and the power source should be the correct answer.
That's just what I would do though.
A compound accepts electrons from another substance to form a covalent bond. The compound acts as a Lewis base.
<h3>What are the most common acid-base theories?</h3>
- Arrhenius: acids release H⁺ and bases release OH⁻.
- Bronsted-Lowry: acids donate H⁺ and bases accept H⁺.
- Lewis: acids accept electrons and bases donate electrons.
A compound accepts electrons from another substance to form a covalent bond. Which term best describes this compound’s behavior?
- Lewis acid. YES.
- Arrhenius base. NO, because OH⁻ is not involved.
- Bronsted-Lowry acid. NO, because H⁺ is not involved.

Answer:
H₂O is the limiting reactant
Theoretical yield of 240 g Al₂O₃ and 14 g H₂
Explanation:
Find how many moles of one reactant is needed to completely react with the other.
6.5 mol Al × (3 mol H₂O / 2 mol Al) = 9.75 mol H₂O
We need 9.75 mol of H₂O to completely react with 6.5 mol of Al. But we only have 7.2 mol of H₂O. Therefore, H₂O is the limiting reactant.
Now find the theoretical yield:
7.2 mol H₂O × (1 mol Al₂O₃ / 3 mol H₂O) × (102 g Al₂O₃ / mol Al₂O₃) ≈ 240 g Al₂O₃
7.2 mol H₂O × (3 mol H₂ / 3 mol H₂O) × (2 g H₂ / mol H₂) ≈ 14 g H₂
Since the data was given to two significant figures, we must round our answer to two significant figures as well.
