Determine the concentrations of K2SO4, K+, and SO42− in a solution prepared by dissolving 2.38 × 10−4 g K2SO4 in 1.00 L of water. Express all three concentrations in molarity. Additionally, express the concentrations of the ionic species in parts per million (ppm). Note: Determine the formal concentration of SO42−. Ignore any reactions with water.

Which substances have the lowest melting points: ionic covalent, or metallic

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.
