Question

when explaining chemical reactions to a friend, brianna models a reaction by combining ingredients to make a cake. which type of chemical reaction is brianna most likely explaining?
synthesis
decomposition
polymerization
replacement

Explanation:

To determine the chemical reaction type, we analyze each option:

• Synthesis: Involves combining multiple reactants to form a single product (e.g., \( A + B

ightarrow AB \)). Combining cake ingredients (multiple substances) to make a cake (one product) matches this.

• Decomposition: Breaks a compound into simpler parts (opposite of synthesis), which does not fit combining ingredients.
• Polymerization: Forms long polymer chains (specific to monomers forming polymers), not general “combining ingredients” for a cake.
• Replacement: Involves replacing an element in a compound (e.g., single/double replacement), which does not match combining ingredients.

Answer:

A. synthesis
