aluminium is passive towards oxyacids due to formation of protevtive layer of oxide. this protective layer resists the contact of aluminium with water or oxygen thatswhy aluminium is passive towards oxyacids
Examples: nitric acid, sulfuric acid, phosphoric acid, perchloric acid, etc.
Oxoacids are acids specifically containing oxygen. Different oxyacids are defined by their extra elements, but all of them contain hydrogen and oxygen.
To evaluate the strength of the aggregate in order to give a clear overview about the tested material.
Neanderthals were -much- stronger than modern humans. They, just like all other primates, had just as much upper body strength as they did lower body strength. We sacrificed our upper body strength in order to require less food. This is what helped us survive over neanderthals.
Fluorine can not form oxyacids because fluorine is more electronegative than oxygen, and oxyacids are formed only from elements that are less electronegative than oxygen.

Sulfuric acid, Sulfurous acid, Nitric acid
Oxyacids of iodine are:- iodic acid: HIO3- iodous acid: HIO2- hypoiodous acid: HIO- ortho periodic acid: HIO4- meta periodic acid: H5IO6
an acid which contain hydrogen and non metallic element and no oxygen.
HCl4(AQ)
in my opinion flourine is very electronegative and it cannot exist in positive oxidation states in its compounds .in oxyacids of halogens ,oxygen carries a negative charge while the halogen carries a positive charge.the electronegativity of flourine is 4,while that of oxygen is 3.5. so due to high value of electronegativity ,flourine shows reluctance to form positive oxidation states and donot form oxyacids........
H2 and a polyatomic ion e.g.) H2CO3 (carbonic acid) hope that helps:)
It means: As embodied acid formation oxyacids.....
