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:

• Synthesis reaction: In a synthesis reaction, two or more reactants combine to form a single product. Here, combining ingredients (reactants) to make a cake (a single product) is analogous to a synthesis reaction.
• Decomposition reaction: Involves a single reactant breaking down into two or more products. This is the opposite of what is described (combining ingredients), so it is not the answer.
• Polymerization: Is a type of reaction where small molecules (monomers) combine to form a large - chain or network - like molecule (polymer). While it is a form of combination, it is a more specific type of reaction (usually forming long chains) and not the most general analogy for combining ingredients to make a single entity like a cake.
• Replacement reaction: Involves one element or group replacing another in a compound. This does not match the description of combining ingredients.

Answer:

synthesis
