QuestionEnter electrons as $\mathrm{e}^{-}$. Use smallest possible integer coefficients. If a box is not needed, leave it blank.
For the following electron-transfer reaction: $$\mathrm{Ni}(\mathrm{~s})+\mathrm{Cl}_{2}(\mathrm{~g}) \longrightarrow \mathrm{Ni}^{2+}(\mathrm{aq})+2 \mathrm{Cl}^{-}(\mathrm{aq})$$
The oxidation half-reaction is: $\square$ $+$ $\square$ $$\longrightarrow$$ $\square$ $+$ $\square$
The reduction half-reaction is: $\square$ $+$ $\square$ $$\longrightarrow$$ $\square$ $+$ $\square$
