The normal boiling point for H2Te is higher than the normal boiling point for H2Se. This can be explained by The normal boiling point for H2Te is higher than the normal boiling point for H2Se. This can be explained by larger hydrogen-bond forces for H2Te. larger dipole-dipole forces for H2Te. larger dipole-dipole forces, smaller dispersion forces, and smaller hydrogen-bond forces for H2Te. larger dispersion forces for H2Te.

Achemist requires 6.00 liters of 0.320 m h2so4 solution. how many grams of h2so4 should the chemist dissolve in water? 121 grams 159 grams 176 grams 188 grams

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.
