Daphne generates a graph with an equation of y=18.34x+0.0010. the graph has Abs plotted on the yaxis and [Cu^2+], M plotted on the xaxis. if the [Cu^2+] =0.0125 M what is the absorbance (Abs)? given that Abs = 18.34[Cu^2+]+0.0010, solve for Abs

The pressure in a fluid is affected by which characteristics of that fluid

The diagram shows the positions of the sun, moon and earth during spring tides, when the high tides are at their highest and low tides at their lowest. what is it about these positions that causes these high and low tides?

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.
