What ions are filtered and exchanged in the kidney tubules?
Sodium (Na+) Potassium (K+) Chloride (Cl-) Bicarbonate (HCO3-) Hydrogen (H+) Calcium (Ca2+) Magnesium (Mg2+)
Which ions are not spectator ions in the precipitation equation Pb(NO3)2 plus 2KI -- and gt PbI2 and nbsp plus 2KNO3?
The spectator ions in this precipitation equation are K+ and NO3-. The non-spectator ions are Pb2+ and I-. They combine to form the precipitate PbI2.
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.

What is bigger KB or K?
They are both the same, short for kilobytes.
How many electrons of MG plus 2?
The atomic number of Mg (and not written as mg) is 12. So there are 12 protons and 12 electrons Note: Mg is the symbol for the element magnesium mg generally stands for milli grams

What are cations?
Cations are positively charged ions. •Na+ •K+ •Ca2+ •Mg2+
The pb k-egde xanes data reveals that pb is in a mixed valence state of pb4 plus and pb2 plus however in literature pb is claimed to be in pb2 plus state the pb 6s2 electrons hybridize with the o 2p?
The Pb K-egde Xanes data reveals that Pb is in a mixed valence state of Pb4+ and Pb2+. However in literature Pb is claimed to be in Pb2+ state. The Pb 6s2 electrons hybridize with the O 2p electrons to form strong covalent bonding which results in the relative displacement of Pb cage with respect to the O-octahedron. This results in increase ferroelectric properties of PbTiO3.However the question is that in the covalent state of the Pb2+ will it appear as Pb4+ state in the Pb K-edge? The reason argued here is that the Pb will lose the 6s2 electrons to form the bond and hence appear to be Pb4+. Hence the argument placed by this pool of thought is from the EXAFS data what appears to be Pb4+ is actually the covalently bonded Pb2+ while what appears to be Pb2+ is actually the ionic type Pb2+.What is the oxidation state of Pb and Ti in PbTiO3 ?
Net ionic equation for lead2 nitrate and potassium iodide?

What is the net ionic equation of lead II nitrate with potassium bromide?
The chemical reaction is: 2 (K+ + Br-)(aq) + (Pb2+ + 2 [NO-3])(aq)----------------- 2 (K+ + [NO-3]) + PbBr2(s)

What ions are filtered and exchanged in the kidney tubules?
Sodium (Na+) Potassium (K+) Chloride (Cl-) Bicarbonate (HCO3-) Hydrogen (H+) Calcium (Ca2+) Magnesium (Mg2+)
What makes soil have a high pH level?
Potassium K+, calcium Ca2+, Magnesium Mg2+ and Sodium Na+ ions are the main contributors to high soil pH (i.e. they cause the soil to become alkaline).
