K2CO3
Potassium carbonate
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.
calcium cation = Ca2+ carbonate ion = CO32- the charges should cancel and you have the correct formula
The polyatomic ion formula for carbonate is CO3^2-.
CaCO3 is calcium (Ca2+) carbonate (CO32-)
K2CO3 Potassium carbonate
K2CO3 Potassium carbonate
The correct formula for an ionic compound composed of potassium and hydroxide is KOH, where K represents potassium and OH represents hydroxide.
magnesium * * * * * Oh dear! Magnesium is Mg, not M. No points there for the first answer. The correct answer is M = K/LN
A carbonate is an ionically bonded compound that includes the polyatomic anion with formula CO32-.
The correct formula of potassium hydride is KH. It is composed of one potassium atom (K) and one hydrogen atom (H) bonded together.
Literally, the correct formula for potassium and iodine at standard temperature and pressure would be " K and I2". The formula for the compound formed between potassium and iodine, however, is KI.
the formula of potassium carbonate is k2co3 because the valency of potassium (k1+) valency of carbonate is (co32-) interchange the valencies and don't put the signs then it will become (k2co3) so the formulae of potassium carbonate is k2co3
