formula PbO2 IS A. lead (I) oxide B. lead (II) oxide C. lead (III) oxide D. lead (IV) oxide 23. The name of the compound KClO2 is potassium A. hypochlorite B. chlorite C. chlorate D. perchlorate 24. What is the correct IUPAC name for the compound NH4Cl? A. nitrogen chloride B. nitrogen chlorate C. ammonium chloride D. ammonium chlorate 25.
PbO_2 For each Pb^(4+) we need two negative oxide ions O^(2-) to balance out total positive and total negative charge. The ratio of Pb^(4+) and O^(2-) ios is 1:2 and hence the formula is PbO_2.Silver Dichromate Chemical Formula. Silver Dichromate is a chemical compound which can be represented using the chemical symbol Ag 2 Cr 2 O 7. It is Solid in state and appears like Ruby Red Powder. When it is added to the hot water, it is decomposed. It is formed by the combination of the aqueous solution of Potassium dichromate and silver nitrate.
My explanation is as follows: I consider the interaction between the atomic orbitals of the lead (II) and lead (IV) cations with the chloride ions. Firstly, we must note that their valence electronic configurations are different: lead(II) has its valence electrons in 6s orbital while the valence electrons of lead (IV)...Calcium nitride is formed along with the oxide, CaO, when calcium burns in air. It can be produced by direct reaction of the elements: 3 Ca + N 2 → Ca 3 N 2. It reacts with water or even the moisture in air to give ammonia and calcium hydroxide: Ca 3 N 2 + 6 H 2 O → 3 Ca(OH) 2 + 2 NH 3
