which statement best describes the two reactions? a cl₂ + h₂ → 2hcl b ₁²h + ₁³h → ₂⁴he + ₀¹n reaction a involves a greater change, and reaction b involves a change in element identity. reaction b involves a greater change and a change in element identity. reaction a involves a greater change and a change in element identity. reaction b involves a greater change, and reaction a involves a change in element identity. done

which statement best describes the two reactions? a cl₂ + h₂ → 2hcl b ₁²h + ₁³h → ₂⁴he + ₀¹n reaction a involves a greater change, and reaction b involves a change in element identity. reaction b involves a greater change and a change in element identity. reaction a involves a greater change and a change in element identity. reaction b involves a greater change, and reaction a involves a change in element identity. done

Answer

Brief Explanations:

Reaction A is a chemical reaction where two elements combine to form a compound, but no change in element identity occurs as hydrogen and chlorine remain hydrogen and chlorine in the compound. Reaction B is a nuclear - fusion reaction where hydrogen isotopes combine to form helium, which is a change in element identity. Nuclear reactions involve much greater energy changes compared to chemical reactions.

Answer:

Reaction B involves a greater change and a change in element identity.
