Question

aqueous copper (ii) nitrate reacts with aqueous sodium hydroxide to yield solid copper (ii) hydroxide and aqueous sodium nitrate. the equation below represents the balanced reaction. complete the equation by filling in the phase indicators. solid = s liquid = l gas = g aqueous = aq cu(no3)2 ( ) + 2 naoh ( ) -----> cu(oh)2 ( ) + 2 naoh ( )

Explanation:

Step1: Analyze reactants' phases

The problem states "aqueous copper (II) nitrate" and "aqueous sodium hydroxide". So, \(Cu(NO_3)_2\) is aqueous (\(aq\)) and \(NaOH\) is aqueous (\(aq\)).

Step2: Analyze products' phases

It mentions "solid copper (II) hydroxide" and "aqueous sodium nitrate". So, \(Cu(OH)_2\) is solid (\(s\)) and \(NaNO_3\) is aqueous (\(aq\)).

Answer:

\(Cu(NO_3)_2(aq)+2NaOH(aq)\to Cu(OH)_2(s)+2NaNO_3(aq)\)
