You have been asked to run a jar tests to determine the amount of coagulant will be required to treat drinking water from a lake. The concentration of the coagulant in your lab is 2000 mg/L and you are working with the standard 1L sample volume. How much of the stock solution must you add to the sample If the coagulant concentration desired in your specific test is 20 mg/L, the quantity (mL) of the stock solution must you add to the sample is most nearly:

Ase your answer to this question on the information below.hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant.the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen.chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product.nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.
