Finely ground nickel(ii) hydroxide is placed in a beaker of water. it sinks to the bottom of the beaker and remains unchanged. an 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)
