What are some oxyacids?
Examples: nitric acid, sulfuric acid, phosphoric acid, perchloric acid, etc.
What is valency of aluminum?
A neutral aluminum atom has 3 valence electrons.
What 3 things do an oxyacid contain?
Oxoacids are acids specifically containing oxygen. Different oxyacids are defined by their extra elements, but all of them contain hydrogen and oxygen.
What metals Aluminum Copper Iron Magnesium Manganese or Zinc should be the most reactive towards oxygen?
magnesium is most reactive
Is the pen was missing active or passive?
passive
Why fluorine cannot form oxyacids?
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.
Acids that have three or more elements?
Sulfuric acid, Sulfurous acid, Nitric acid
Would you expect aluminum oxide to decompose readily upon heating?
Aluminum oxide will not decompose readily upon heating because it is a very stable oxide. Aluminum oxide is passive and is less affected by environmental factors.
What is passivation?
Passive means, not active. It has a number of applications - in grammar a verb can be passive, in electronics, components such as resistors, capacitors or inductors are passive (transistors are active).
What are the names and formulas for the oxyacids and iodine?
Oxyacids of iodine are:- iodic acid: HIO3- iodous acid: HIO2- hypoiodous acid: HIO- ortho periodic acid: HIO4- meta periodic acid: H5IO6
What is the IUPAC systematic name for ternary oxyacids HClO4(AQ)?
HCl4(AQ)
What is a non-oxyacids?
an acid which contain hydrogen and non metallic element and no oxygen.
How do you attract a pig in minecraft?
If you hold wheat in your hand, all passive mobs, including pigs, will come towards you.
Why does the action of concentrated nitric acid render aluminum passive?
nitric acid is light sensitve , it decomposes when expose in light. when aluminium is added to the conc HNO3 it remain passive in conc nitric acid,...... and moreover aluminium oxide layer is also form due to which it remain passive in conc nitric acid...
Why cant fluorine form oxyacids?
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........
What is the part of oxyacids?
H2 and a polyatomic ion e.g.) H2CO3 (carbonic acid) hope that helps:)
What happens when aluminium and oxygen combine?
A passive aluminum oxide layer will form on the surface of the aluminum, when it is in the presence of Oxygen (Al2O3). This then goes on to protect the rest of the aluminum from further oxidisation as the layer will remain in place, bonded to the aluminum.
