To understand why PbO and PbO2 differ in their reactivity with HCl, we can analyze the reactions and the oxidation states of lead in both compounds. Here’s a step-by-step breakdown:Step 1: Analyze the Reactions1. Reaction of PbO with HCl:2...
PbO and PbO2 react with HCl according to the following chemical equations: 2PbO + 4HCl → 2PbCl2 + 2H2O PbO2 + 4HCl → PbCl2 + Cl2 + 2H2O Why do these compounds differ in their reactivity? Solution: In reaction (i), none of the atoms changes. Therefore, it is not a redox rea...
c = 2 (HCl) d = 1 (PbO) Step 4: Substitute Coefficients and Verify Result Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. ...
To calculate the limiting reagent, enter an equation of a chemical reaction and press the Start button. The reactants and products, along with their coefficients will appear above. Enter any known value for each reactant. The limiting reagent will be highlighted in red. ...
It is assumed that during the polymerization process, the dissolution of TA and the diffusion of the macromolecules in PPA are relatively slow, which leads to the results that the rate of polymerization is not too fast.

The electrodes production is a complicated and costly process which is generally done in a laboratory or a clean room. This has created a barrier to scaling up for the site application too. Fortunately, PbO2 has generally been used in lead-acid batteries as the anode material, the reaction ...
PBO聚合物合成反应一般分为两步进行n虻”。首先是DADHB单体脱除 HCL增加其活性,在此过程中要补加P205,以溶解DADHB和保护活化的单体 不被氧化。然后是胺与酸的缩合脱水反应过程。由于对苯二甲酸(TA)在多聚 磷酸(PPA)中的溶解度非常小,DADHB单体的转化率始终高于1A单体转化...
