K2CO3
Potassium carbonate
(Don't forget to balance it) The precipitate here has to be 2NaCl, as Ca(CO3)2 technically dissolves.
The correct ansewer is 8
It is not correct to say that 8 plus 2 8r-2r 4 3r plus 2 r = 0
(10 + 1) x 10/2
The balanced chemical equation for the reaction is: 2 Al₂(CO₃)₃ + 3 ZnCl₂ → 3 ZnCO₃ + 2 AlCl₃. The correct coefficients in order are 2, 3, 3, and 2.
K2CO3 Potassium carbonate
Sodium: Na or the ion Na+ Carbonate: (CO3)2-
The correct formula for an ionic compound containing Al3+ and CO32- is Al2(CO3)3. This is because aluminum has a 3+ charge, and carbonate has a 2- charge, so to balance the charges, you need two aluminum ions for every three carbonate ions.
Cobalt phosphate has the chemical formula Co3(PO4)2.
The formula for ruthenium(IV) carbonate is Ru(CO3)2.
The chemical formula of lead(IV) carbonate is Pb(CO3)2.
The chemical formula for gold carbonate is Au2(CO3)2.
The balanced chemical equation for the reaction between Al2(CO3)3 and ZnCl2 to form ZnCO3 and AlCl3 is: Al2(CO3)3 + 3 ZnCl2 → 3 ZnCO3 + 2 AlCl3
Dolomite is a crystal of calcium magnesium carbonate, CaMg(CO3)2.
This formula is Sn(CO3)2.
The chemical formula for stannic sulfate is Sn(SO4)2.
