61.) Consider the neutralization reaction that takes place when hydrochloric acid reacts with solid nickel(II) carbonate. a. Write a conversion factor that relates moles of HCl to moles of NiCO3 for this reaction. b. What is the minimum volume of 6.0 M HCl necessary to react completely with 14.266 g of solid nickel(II) carbonate, NiCO3?
NiCO3(s) +2HCl ------------------> NiCl2 (s) + CO2 + H2O
1 mole 2 moles
no of moles of NiCO3 = W/G.M.Wt = 14.266/118.7 = 0.12 moles
1 mole of NiCO3 react with 2 moles of HCl
0.12 moles of NiCO3 react with = 2*0.12/1 = 0.24 moles of HCl
no of moles of HCl = molarity * volume in L
0.24 = 6*volume in L
volume in L = 0.24/6 = 0.04 L = 40ml >>>>>answer
