Here are the answers to your questions:
**Question 1**
A) Which option describes something that causes ionic bonds to form?
**Response**: **large electronegativity differences**
Reason: Ionic bonds form between atoms with a large difference in electronegativity, leading to the complete transfer of electrons from one atom to another.
---
**Question 2**
A) In a replacement reaction, which metal would replace aluminum?
**Response**: **zinc**
Reason: In the reactivity series, zinc is more reactive than aluminum, which means it could potentially displace aluminum in a reaction.
---
**Question 3**
A) In a replacement reaction, which nonmetal would replace chlorine?
**Response**: **fluorine**
Reason: Fluorine is more reactive than chlorine; therefore, it can displace chlorine in a replacement reaction.
---
**Question 4**
A) Combustion reactions release _____.
**Response**: **energy and light**
Reason: Combustion reactions are exothermic processes that produce energy (usually in the form of heat) and light.
---
**Question 5**
A) Which products are expected from the reaction C10H8 + 12O2 → ?
**Response**: **10CO2 + 4H2O**
Reason: The complete combustion of C10H8 (naphthalene) in the presence of oxygen produces carbon dioxide (CO2) and water (H2O). The stoichiometry of the reaction yields 10 moles of CO2 and 4 moles of H2O.
