Chemistry help 10 points for answer!!!!!!!!!!!!!!!?
Write the chemical formula of the neutral compound formed from the ions below
1. Cu2+ ions and NO3– ions
2. Ag+ ions and CrO42– ions
3. There are two possible methods for recovering copper from a solution of copper (II) sulfate, one uses precipitation and the other uses redox.
a) Copper(II) ions can be precipitated as copper(II) carbonate.
CuSO4(aq) + Na2CO3(aq) → CuCO3(aq) + Na2SO4(aq)
How many mL of 0.139 M Na2CO3 would be needed to precipitate all of the copper ions in 27.5 mL of 0.170 M CuSO4?
