Acovalent bond between to atoms results when the atoms lose or gain electrons share electron pairs transfer valence electrons conmpletely from one atom to the other realease energy

If 10.g of agno3 is available, what volume of 0.25 m agno3 can be prepared

Which type of bonding involves the complete transfer of a valence electron from a less electrogrative atom to a more electronegative one

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.
