two potassium ions balance one sulfide ion.
Potassium is K+, Sulfide is -2, so 2xK+ + 1x-2 = 0
so it can be balanced out
4 because its a cool number
Two. the sulfide ion is S2- so two K+ ions are required to balance the charges
Exactly 2
The chemical formula of potassium dichromate is K2Cr2O7
so it can be balanced out
4 because its a cool number
Normally, 2 K+ ions are required for making a stable ionic bond with one S 2- anion. The compound formed would be Potassium Sulfide (K2S).
Two. the sulfide ion is S2- so two K+ ions are required to balance the charges
so it can be balanced out
Exactly 2
The chemical formula of potassium dichromate is K2Cr2O7
The chemical formula starts out with the two ions, the calcium and sulfide ions. Calcium's ion is Ca2+, while the sulfide ion is S2-. Because the net ionic charge of a compound is zero, only one of each atom is needed to create calcium sulfide, which will be CaS.
Sodium chloride is neutral.
Calculate the mass (in grams) of sodium sulfide that is needed to make 360ml of a 0.50 mol/L solution
Three Potassium Ions are needed to Bond with one Phosphate Ion.
Yes, potassium is healthy. Also, if you ever needed some carrots, beans, bananas etc. contain potassium.
