A combination of Planet X elements (vibranium and bazoolium) and Earth elements are being studied in this question.  If  142.5 mL of 0.60 M vibranium (II) nitrite [V(NO3)2] are mixed with 150.0 mL of 0.80 M bazoolium iodide [BzI], the vibranium (II) iodide precipitates out.  The atomic mass for vibranium is 1596 amu.  Which of the following statements is true? The final concentration of vibranium ions is 0.0872 M. The final concentration of nitrite is 0.821 M. None of the statements are true. You form 111 g of vibranium (II) iodide. The final concentration of bazoolium ion is 0.410 M.

In the laboratory you are given the task of separating Ba 2+ and Co2+ ions in aqueous solution. For each reagent listed below indicate if it can be used to separate the ions. Type "Y" for yes or "N" for no. If the reagent CAN be used to separate the ions, give the formula of the precipitate. If it cannot, type "No" Y or N Reagent Formula of Precipitate if YES 1. Na2CO3 2. K2SO4 3. NaI

40 ml of a 0.100 M sodium phosphate solution is mixed with 40 ml of a 0.200 M cobalt (II) nitrate solution, generating a fine purple solid. The solid is removed via filtration and the liquid is saved.  Given that nitrate compounds are always soluble and phosphate compounds are generally insoluble, what chemical species are present in the precipitate and in the supernatant? Explain your answer.

In addition to filling in the blanks below, show all of your work for this problem on paper for later upload. When 25.0 mL of 0.800 M Ca(NO3), is added to 75.0 mL of 0.600 M NaF, CaF2 precipitatės. Write the limiting reactant in the box below; write None if neither reactant limits. Determine the number of moles of calcium fluoride produced in this reaction and enter it into the box below. The initial temperature of both solutions is 25.00°C. What is the final temperature if the specific heat of the solution is 4.184 J/(g °C), and the density of the solution is 1.000 g/mL? The reaction and associated heat follows:
