Select the correct answer. In which of the following equations will Ke = K?
OA. 2H2(g) + C2H2(g) = C2H6(g)
OB. 2NO(g) + O2(g) = 2NO2(g)
OC. N2(g) + O2(g) = 2NO(g)
OD. 2H2(g) + O2(g) = 2H20 (g)

What’s the scientific notation for the number 6,840,000,000

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.
