The analysis of DDT in a water sample resulted to a peak area of 0.250. Calibration curve is NOT prepared since standard solutions are limited. Therefore, a 1.00 ppm DDT standard is spiked in the same water sample. This resulted to an increase in peak area. The peak area of the spiked sample is now 0.315. What is the DDT concentration in the water sample? 3.75 ppm 3.85 ppm 5.09 ppm 1.43 ppm 1.65 ppm

Nickel(II) formate [Ni(HCO2)2] is widely used as a catalyst precursor and to make metallic nickel. It can be prepared in the general chemistry laboratory by treating nickel(II) acetate with formic acid (HCO2H). Ni(CH3CO2)2(aq) + 2 HCO2H(aq) Ni(HCO2)2(aq) + 2 CH3CO2H(aq) Green crystalline Ni(HCO2)2 is precipitated after adding ethanol to the solution. (a) What is the theoretical yield of nickel(II) formate from 0.500 g of nickel(II) acetate and excess formic acid? (b) Is nickel(II) formate paramagnetic or diamagnetic? If it is paramagnetic, how many unpaired electrons would you expect? (c) If nickel(II) formate is heated to 300 C in the absence of air for 30 minutes, the salt decomposes to form pure nickel powder. What mass of nickel powder should be produced by heating 253 mg of nickel(II) formate? Are nickel atoms paramagnetic?
The Handbook of Chemistry and Physics (http://openstaxcollege.org/l/16Handbook) gives solubilities of the following compounds in grams per 100 mL of water. Because these compounds are only slightly soluble, assume that the volume does not change on dissolution and calculate the solubility product for each. (a) BaSeO4, 0.0118 g/100 mL. (b) Ba(BrO3)2H2O, 0.30 g/100 mL. (c) NH4MgAsO46H2O, 0.033 g/100 mL. (d) La2(MoO4)3, 0.00179 g/100 mL

A saturated silver carbonate solution (1.0 L) is preparedat 5 °C and filtered to separate the undissolved phase. The filtrate is treated at 25 °C withhydrochloric acid, whereby the carbonate ions decompose and carbon dioxide is formed. The measurement shows thatthe level of carbon dioxide above the reaction vessel is 600 ppm. All carbon dioxide gas formed is collected ina test tube with a volume of 19 mL, and at 25 °C the pressure is measured to be 114 mmHg. CalculateKsp for silver carbonate at 5 °C.
