What is Al2O in chemistry?

Aluminium(I) oxide. Al2O.

What does the formula K2s indicate that?

That is why the formula of potassium chloride is KCl (1:1) whilst the formula of potassium sulfide is K₂S (2:1). Hey! Answer: The 2 shows the number of potassium ions present in the compound, and the 2 is needed to show that 2 potassiums are needed to balance the charge on the sulphur ion.

How to write the formula for potassium sulfide (K2S)?

Potassium sulfide is an inorganic compound with the formula K 2 S. The colourless solid is rarely encountered, because it reacts readily with water, a reaction that affords potassium hydrosulfide (KSH) and potassium hydroxide (KOH). Most commonly, the term potassium sulfide refers loosely to this mixture, not the anhydrous solid.

Is K2s soluble or insoluble in water?

Potassium sulfide, or K2S is a solid and colorless inorganic compound. Chemically spoken lead (II)sulfate is slightly soluble in water. The answer that Copper (II) phosphate is insoluble in water. A common threshold to describe something as insoluble is less than 0.1 g per 100 mL of solvent. Thanks for the help.
