Regents Chemistry Exam June 2025 Question 7


7 Which term identifies a chemical property that can be used to differentiate a sample of sodium from a sample of gold?

(1) density (3) reactivity (2) mass (4) temperature


Solution:

Chemical property is a property that describes how a substance reacts with another substance and changes its identity. For example, iron can react with oxygen to form rust. Reactivity, choice 3 is the correct answer choice. The rest of the answer choices describe physical properties.
