(vi) Ion-induced dipole interactions [20(b)] In these interactions ion’s field induces a dipole moment in a molecule. If μ is the induced moment in a field E‚ ‘α’ is the polarizability (assumed to be constant)‚ then (26) (27) where FZ is the instantaneous force on the induced dipole (R >> δ) and the interaction energy at a given R‚ is (28) As the induced dipole is parallel to the field

LAB 3.Ø.Ø: do ions combine in definite ratios PURPOSE The purpose of this investigation is to determine whether ions combine in definite ratios or not. To observe‚ and create a table of the different ions. QUESTION If copper (II) sulfate when mixed with sodium carbonate at different quantities combine to form ions in definite ratios. HYPOTHESIS / PREDICTION I believe that the ions will combine in definite ratios due to the fact that the valance electrons will not be changing throughout any

It helps‚ in trying to see the periodic pattern‚ to know the pattern that results when we do a separation and analysis of all metal ions. PROCEDURE Procedure A 1. 2 drops of 6 M HCl was added to 1 ml of the mixture of the metal cations. 2. The suspension was centrifuged for 1 minute as ppt. of chloride was formed. 3. 1 additional drop of 6 M HCl was added to the clear

Urea is produced in the liver from excess amino acids. Where are the substances excreted? Carbon dioxide is passed from the cells of respiring tissues into the blood stream. It is transported in the blood (mostly in the form of hydrogen carbonate ions) to the lung. In the lungs the carbon dioxide diffuses into the alveoli to be excreted as we breathe out. Urea is produced by breaking down excess amino acids in the liver. This process is known as deamination. The urea is then passed through the
