Hey guys! Help me please! :) CrCl2 + Li2CO3 --->? Kl +NaCl LiNO3 + Na2SO4 Na2CO3 +CuCl2 KOH + FeCl3 Which ones have precipitate forms and which ones have no reaction? Use Le Chatelier’s principle to predict how the equilibrium concentration of the FeCl2+ ion will change when an aqueous solution of silver (I) nitrate, AgNO3, is added to the exothermic reaction below. May 16, 2011 · 1) FeCl2(aq) + KOH(aq) 2) HNO3(aq) + CuSO4(aq) 3) Hg(NO3)2(aq) + Na3PO4(aq) Fe(OH)2 = solid (or slightly soluble) Hg3[(PO)4]2 = solid. Cl with any cation = aqueous Oct 09, 2019 · The finished reaction is: 2 KCl(aq) + Pb(NO 3) 2 (aq) → 2 KNO 3 (aq) + PbCl 2 (s) The solubility rules are a useful guideline to predict whether a compound will dissolve or form a precipitate. There are many other factors that can affect solubility, but these rules are a good first step to determine the outcome of aqueous solution reactions. Mar 16, 2007 · Write the balanced net ionic equations for each of the following reactions: 1) A soluition of sodium thiocyanate id added dropwise to a solution of nickel chloride 2) Solid calcium oxide is heated in the presense of sulfur trioxide gas 3) Equal volumes of .1 M sulfuric acid and .1 M potassium hydroxide are mixed. 4) Calcium metal is heated strongly in nitrogen gas. 5) Solutions of .1 M ammonia ... Aug 07, 2016 · Since iron(III) nitrate and iron(III) hydroxide are in a 1:1 mole ratio in the balanced chemical reaction, you can say that the reaction will produce 0.00330 moles of iron(III) hydroxide. 2) Predict the products of a reaction when given the reactants. Section 1: Identify the type of reaction. For the following reactions, indicate whether the following are examples of synthesis, decomposition, combustion, single displacement, double displacement, or acid-base reactions: 1) Na3PO4 + 3 KOH ( 3 NaOH + K3PO4 _____ An excess of silver nitrate was added to precipitate the chloride ion as silver chloride.
