K2S or potassium sulfide is an ionic compound.
Ionic, yes
Ionic bonding
Potassium sulfide has an ionic bond.
Yes, potassium sulfide is ionic.
NH3 contains covalent bond
Formula for potassium sulfide is K2S.
K2S + 2HCl --> 2KCl + H2S
Neon does not form bonds with potassium.
If you have 2 moles of K+ for every mole of K2S and Molarity (M) is Moles per Liter. Then you know that you have .30 M of K2S. The way that you do that is setting up a series of conversion factors like so:(.15moles k2s/liter) x (2 moles of K/ 1 mole of K2S) = .30 moles k/ liter.The moles of K2S cancel out and you are left with moles of K per liter.
K2S will have high boiling point than CH3Cl.
Potassium has a formal charge of +1, and sulfide has a formal charge of -2, so: K2S
