Lets first take the case of the d3 compound. The no.of orbitals in the 3d shell is 5. If three electrons occupy three orbitals then there are two free orbitals.Therefore According to Valence bond theory the six water ligands will use the two inner d orbitals the outer s and the p orbitals to form an inner orbital complex with hybrisation d2sp3. In the second case we have the d5 compund. Since there are five electrons in the d subshell the five electrons singly occupy all the five d orbitals. Here 's where the concept of the weak ligand comes in. Since water is a weak ligand it cannot force pairing of the unpaired d electrons to make room for an inner orbital complex. Thus it has to use the outer d orbital to form an outer orbital complex with hybridisation of sp3d2. Since the Inner orbital (low spin) complex is more stable than the outer orbital (high spin) complex. Thus d3 configuration is more stable than d5 configuration in aqueous medium.
as you now Fe configuration end by 4s2 3d5 we have to kind of hypredization depening on the lligand inter to Fe i will tak about d2sp3 just if the bonded ligand strong the electron in d5 will be compressed as follows 1 1 1 1 1 2 - - - d5 s2 3p empty will becom after intering a strong ligand 2 2 1- - 2 --- d5 with s2 3p empty 2 empty so the hypredization will be between 2 orbital from d with s orbital and 3 orbital of p producing d2sp3 and the complex called inner complex والله تعالى اعلم عبدالعزيز ابويامين
water is the most common solvent in the body
Sugar Water , Muddy Water , Sand Water.
Water evaporates faster than salt water and sugar water.
The solution is used to add water, sucrose and sodium to the organism.
D5N2 i/v fluids
Plain Lactated Ringers (PLR) - Blue Plain Normal Saline Solution (PNSS) - Green D5 Normal Saline Solution (D5NSS) - Yellow D5 0.3 Sodium Chloride (D5 0.3 NaCl) - Light Blue D5 Lactated Ringers (D5LR) - Pink Balanced Multiple Maintenace Solution with 5% dextrose (D5IMB) - Purple Dextrose 5% Water (D5W)- Red D5 Normosol-R (D5NR) - Yellow Green D5 Normosol-M (D5NM) - Orange
The Chords are: A flat 5, B 5, C sharp 5, E5, D sharp 5, E5, D sharp 5, E5, B5, C5 Hope this comes in useful
D5W is hypertonic to solutions containing less than 5% dextrose.
Different grades, D5 is like heating oil that has little to no odor.
This does depend on the year of your car. The original D5 was 163bhp, but later in its life this was increased to 185.
It depence on your engine, most D5 10yrs or 96k mileage.
My 1972 96J D5 weighs 13 tons, or 26,000 lb. It's heavier than newer model D5's, since it was a D6 in prior model years.
d5 for lower rpm's, better fuel economy

This is a hypotonic solution.
