Rubidium chloride adopts the rock salt structure. Compute the radius of the rubidium ion if the density of RbCl is 2.76g/cm3 and it is assumed that the ions touch along the edges of the unit cell.
Define what is the product for Benzene + (benzene ring attached to a carbon which is single bonded to another carbon which is double bonded to an oxygen and single bonded to a Cl) all in the presence of a ALCL3 catalyst
Explain when solutions of cobalt (II) chloride and carbonic acid react, which of the following terms will be present in the net ionic equation
Where do i draw the line between a good leaving group and an excellent leaving group(sn1)? Do i draw the line for a excellent leaving group at all halides
The ozone layer is about 20 km thick, has an average total pressureof 10 mm Hg(1.3 * 10^-2 atm ) , and has an average temperature of 230 K. The partial pressure of ozone in the layer is only about 1.2 * 10^-6 mm Hg( 1.6 * 10^-9 atm ).

How will you prepare the following solutions from 6.0 M solutions of acetic acid and ammonia. Give exact details. Assume that a 10-mL graduated cylinder.
Positronium consists of an electron and a positron (same mass, opposite charge) orbiting round their common centre of mass. The broad feature of the spectrum are therefore expected to be hydrogen-like, the differences arising largely from the mass..
