Question

which three types of reactions yield a product that is a chemically bonded combination of reactants?
○ replacement, polymerization, decomposition
○ polymerization, decomposition, oxidation
○ decomposition, synthesis, replacement
○ oxidation, synthesis, polymerization

Explanation:

1. Analyze each reaction type:

• Synthesis: Combines reactants into a single product (e.g., \( A + B

ightarrow AB \)), so it forms a bonded combination.

• Polymerization: Combines monomers (small units) into polymers (large, bonded structures), forming a bonded combination of reactants.
• Oxidation: Often involves combining with oxygen (or electron loss), which can result in a product that is a bonded combination of reactants (e.g., oxidation of a metal to form an oxide, combining metal and oxygen).
• Decomposition: Breaks a compound into simpler substances (\( AB

ightarrow A + B \)), so it does not form a bonded combination of reactants (eliminates options with decomposition).

• Replacement: Involves replacing parts of compounds (e.g., single - replacement: \( A + BC

ightarrow AC + B \)), not forming a bonded combination of all reactants (eliminates options with replacement).

1. Check the options:

• Option 1: Has replacement and decomposition (incorrect).
• Option 2: Has decomposition (incorrect).
• Option 3: Has decomposition and replacement (incorrect).
• Option 4: Oxidation (combines with O or involves electron - related combination), synthesis (combines reactants), and polymerization (combines monomers) all yield products that are chemically bonded combinations of reactants.

Answer:

D. oxidation, synthesis, polymerization
