K2S
K2S is the formula for the ionic compound formed from potassium and sulfur.
When the equation kmno4 plus mgs k2s plus mgmno42 is balanced, the correct set of coefficients is 2111.
K+1 S-2
The formula mass of potassium sulfide, K2S is 2(39.1)+32.1=110.3 1 mole of potassium sulfide has a mass of 110.3g Mass of 3.3mol of K2S = 3.3 x 110.3 = 364g
Formula for potassium sulfide is K2S.
K2S + 2HCl --> 2KCl + H2S
K2S or potassium sulfide is an ionic compound.
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
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.
It is K2S.
