identify whether each reaction represents a chemical reaction or a nuclear reaction by filling in the blank with the word chemical or nuclear. cl₂ + h₂ → 2hcl this represents a reaction. ₁²h + ₁³h → ₂⁴he + ₀¹n this represents a reaction done

identify whether each reaction represents a chemical reaction or a nuclear reaction by filling in the blank with the word chemical or nuclear. cl₂ + h₂ → 2hcl this represents a reaction. ₁²h + ₁³h → ₂⁴he + ₀¹n this represents a reaction done

Answer

Brief Explanations:

  1. In the reaction $\mathrm{Cl}{2}+\mathrm{H}{2}\rightarrow 2\mathrm{HCl}$, only the outer - shell electrons are involved in bond - breaking and bond - forming. This is characteristic of a chemical reaction.
  2. In the reaction $\ce{_{1}^{2}H + {1}^{3}H\rightarrow{2}^{4}He + _{0}^{1}n}$, the nuclei of the hydrogen isotopes combine to form a helium nucleus and a neutron. Changes in the nucleus are characteristic of a nuclear reaction.

Answer:

  1. chemical
  2. nuclear
