WebIf 100.0 g of KOH is added to 0.900 L of 2.00 M Cu(NO_3)_2, what mass in grams of Cu(OH) will be formed? (Hint: What is the balanced equation for this reaction?) Consider the reaction when aqueous solutions of sodium hydroxide and copper(II) acetate are combined. Write the net ionic equation for this reaction. Web(d) NiCO3(s) + 2 HNO3(aq) Ni(NO3)2(aq) + CO2(g) + H2O(l) 1. Note the need for at least 1 Ni atom on both sides. This inventory will mandate 2 NO3 groups on the right—and also on the left. Since these come from HNO3 molecules,we'll need 2 HNO3 on the left. 2. The 2 H from the acid and the CO3 from nickel carbonate, provide 2H, 1 C and 3 O
