Finely ground nickel(II) hydroxide is placed in a beaker of water. It sinks to the bottom of the beaker and remains unchanged. A

n aqueous solution of hydrochloric acid (HCl) is then added to the beaker, and the Ni(OH ) 2 disappears. Which equation best describes what occurred in the beaker? A. Ni(OH ) 2 (s) + HCl(aq) → NiO(aq) + H 2(g) + HCl(aq) B. Ni(OH ) 2 (s) + 2HCl(aq) → NiC l 2 (aq) + 2 H 2 O(l) C. Ni(OH ) 2 (s) + 2 H 2 O(l) → NiC l 2 (aq) + 2 H 2 O(l) D. Ni(OH ) 2 (s) + 2 H 2 O(l) → NiCl 2(aq) + 3H 2O(l) + O 2(g)
