I'd not normally request help with Dd's homework but these two Q's have got her stumped. Does anyone know the answer to these:

What is the strongest acid which has a Q in it's name?

Question J: Zinc will______displace iron from iron sulphate solution. DD and I want to put "Just about"!grin

can't think of an acid with Q in its name, am racking my brains!
Zinc will displace iron from iron sulphate solution - that's true, why is a gap needed?!! You might be right in thinking that it's 'just', but that seems daft!
