Pb is a transition metal with only 1 oxidation state?
No, Pb is not a transition metal and it has 2 oxidation states
How do you produce lead dioxide from lead carbonate?
It'll decompose by heating, releasing carbondioxide: Pb(II) or plumbous carbonate: Pb(CO3) --> PbO + CO2 or Pb(IV) or plumbic carbonate: Pb(CO3)2 --> PbO2 + 2CO2
What is the percent of lead in lead IV oxide Or how do i calculate it?
86.62(8)%The molar masses of the constituent elements must be known.M(Pb) = 2.072(1) x 102 gmol-1M(O) = 1.59994(3) x 10 gmol-1From these and their respective molar ratios in the compound, the total molar mass of the compound must be calculated.M(PbO2) = M(Pb) + 2M(O)M(PbO2) = (2.072 x 10 gmol-1 + 2(1.59994 gmol-1)) x 10M(PbO2) = 2.392(1) x 102 gmol-1From the molar mass of the element in question and its ratio, and the compound, their total masses present in one mole of compound must be calculated.m = nMm(Pb) = 1 mol x 2.072 x 102 gmol-1m(Pb) = 2.072(1) x 102 gm(PbO2) = 1 mol x 2.392(1) x 102 g (always 1 mole)m(PbO2) = 2.392(1) x 102 gFrom these, the percentage of the element in question present in the compound can be calculated.m(Pb) x 100%/m(PbO2) = 2.072 g x 100%/2.392 gm(Pb) x 100%/m(PbO2) = 86.62(8)%
What is the chemistry of recharging the lead battery?
Dr M KanagasabapathyAsst. Professor in ChemistryRajus college, Affiliated to M K UniversityRajapalayam (TN) India------------------------------------------------------------------------------------------------------Lead acid battery contains the following1. Lead PB2. Lead oxide PbO3. Sulfuric acid H2SO4During discharging Pb Oxidizes to Pb 2+ and PbO2 reduces to Pb2+ from Pb 4+PbO2 + Pb + H2SO4 = 2 PbSO4 + H2O (~ 2.0 V per cell)During charging the reverse reaction takes placePb2+ reduces to lead at cathode and another molecule of Pb2+ oxidizes to PB4+ or PbO2 by reacting with distilled water.2 Pb(2+) + H2O2 = Pb + PbO2 (> 2.0 V per cell)The important thing is the voltage for recharging should be slightly higher than the discharging voltage.During discharging the battery functions as electrochemical cell.And during charging it becomes an electrolytic cell.By,Dr M KanagasabapathyAsst.

Determine the oxidation state of KCIO2?
K = +1 oxidation state Cl = +3 oxidation state O = -2 oxidation state
What is the Oxidation numbers for element PbO2?
-2 for each O +4 for Pb
What is the oxidation number for PbO2?
O is 2- and there are two of them so Pb would have to be 4+
How to balance Pb plus pbo2 plus h2so4 H2O plus pbso4?
Pb + PbO2 + H2SO4 --> PbSO4 + H2O
Pb is a transition metal with only 1 oxidation state?
No, Pb is not a transition metal and it has 2 oxidation states
What is the reaction between nacl plus pbno3?
It has to be Pb(NO3)2 with NaCl as Pb has a +II oxidation state and NO3 has -I oxidation state. The reaction is the following: Pb(NO3)2 +2NaCl ----> PbCl2 + 2NaNO3
What is the oxidation of lead and tin equations?
Tin and Lead are both metals with oxidation numbers of 2+ and 4+, so the two equations for Lead (Pb) are 2Pb + O2 ---> 2PbO and Pb + O2 ---> PbO2 The equations for Tin (Sn) look the same ... just substitute Sn where you see Pb.
What is the chemical equatin of Pb and nitric acid?
Assuming the 2 oxidation state of lead. Pb + 2HNO3 --> Pb(NO3)2 + H2
Which is good oxidising agent PbO2 or PbO?
PbO2....Pb has a 4+ charge and therefore can be reduced to Pb2+ in PbO. Since it can be reduced it is an oxidizing agent.
What is the Chemical composition of battery?
the positive plate is Pb the negative is PbO2 and the acid is H2SO4.
What is the balanced equation representing the decomposition of lead IV lead?
PbO2 > Pb+O2
What is the formula for plumbic oxide?
The formula for plumbous oxide is PbO.
What is the ionic formula for lead 4 oxide?
The ionic chemical formula of lead(IV) oxide is: (Pb)4+ + 2 O-.
