How many grams of solid calcium bromide (199.9 g/mol) must be added to 458 mL of a 1.6 M sodium bromide solution to bring the total concentration of bromide ion in the solution to 4.6 M? Assume the volume of the solution does not change upon adding the solid

Adozen is 12, and your needing to calculate the weight of one medium egg, so i would do 21/12=1.75 per egg, and check your answer by doing 1.75 * 12= 21 : ) : ): ): ): ) i hoped i

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

It is a product
