In chemisty? Is ita sulphate or a sulphide?

Sulfide or sulfate according to IUPAC

could well be, I never learned chemisty

Learning chemistry also crucially includes learning how to spell the

Air controller to first airliner "What height are you at?"
"I am at thirty thousand feet"
Air controller to second airliner "And What height are you at?"
"I am at thirty, too.."
