Potassium sulfide
Formula for potassium sulfide is K2S.
K2Sthat it.
To find the mass of 1.474 mol of potassium sulfide, you need to multiply the number of moles by the molar mass of potassium sulfide. The molar mass of potassium sulfide (K2S) is approximately 110.26 g/mol. Therefore, the mass of 1.474 mol of potassium sulfide is about 162.62 grams.
The formula unit for potassium sulfide is K2S. It consists of two potassium ions (K+) and one sulfide ion (S2-).
The name of the ionic compound k2s is= Potassium Sulfide
The formula for potassium sulfide is K2S. It consists of two potassium (K) ions and one sulfide (S) ion, which combine to form an ionic compound.
Potassium has a formal charge of +1, and sulfide has a formal charge of -2, so: K2S
The chemical symbol for Potassium Sulphate is K2SO4
two potassium ions balance one sulfide ion. Potassium is K+, Sulfide is -2, so 2xK+ + 1x-2 = 0
The formula for potassium hydrogen sulfide is KHS. Another name for this inorganic compound is potassium hydrosulfide. Its molar mass is 72.17 grams per mole, and it is soluble in water.
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).
