please hurry up and answer this question If 36.6 mL of 1.2 M sodium sulfide solution reacts completely with a solution of aqueous copper (II) chloride, how many grams of precipitate would be expected to form? The chemical reaction: Na2S (aq) + CuCl2 (aq) ----> 2 NaCl (aq) + CuS (s)
Many metal ions are precipitated from a solution by the sulfide ion. As an example, consider treating a solution of copper(II) sulfate with sodium sulfide solution: CuSO4(aq) + Na2S(aq) → CuS(s) + Na2SO4(aq) What volume of 0.104 M Na2S solution would be required to precipitate all of the copper(II) ion from 13.4 mL of 0.120 M CuSO4 solution? Volume = mL Submit Answer Try Another Version 7 item attempts remaining Generally, only the carbonates of the Group 1 elements and...

A solution is prepared by mixing 0.10 L of 0.12 M sodium chloride with 0.23 L of a 0.19 M MgCl2 solution. What volume of a 0.20 M silver nitrate solution is required to precipitate all the Cl− ion in the solution as AgCl?
Heavy metal ions like lead(II) can be precipitated from laboratory wastewater by adding sodium sulfide, Na2S. Will all the lead be removed from 13.4 mL of 7.50×10-3 M Pb(NO3)2 upon addition of 13.9 mL of 0.0121 M Na2S? If all the lead is removed, how many moles of lead is this? If not, how many moles of Pb remain?
