Question

using the information in the table above, make a clai vulcanizing rubber. claim: vulcanizing rubber is a change. which statement best suppor choose 1 answer: a the sulfur atoms are ph n with the molecules. this means

Explanation:

To determine the correct answer, we analyze the nature of vulcanizing rubber:

1. Understand Chemical vs. Physical Change: A chemical change involves the formation of new substances (via chemical bonds), while a physical change only alters form (no new substances).
2. Vulcanization of Rubber: Vulcanizing rubber involves adding sulfur, which forms cross - links between rubber molecules. This creates a new, more durable material with distinct chemical properties (e.g., increased elasticity, heat resistance) than the original rubber. Thus, it is a chemical change, not physical.

Vulcanizing rubber forms new cross - linked molecules (sulfur - rubber bonds), creating a substance with new chemical properties. This fits the definition of a chemical change (not physical, as physical changes do not form new substances).

Answer:

chemical
