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.
