Write the balanced dissociation equation for solid calcium phosphate in aqueous solution. If it does not dissociate, simply write only NR.

n Chapter 14. you learned that the bonding forces in ionic solids such as NaCl are very strong, yet many ionic solids dissolve readily in water. Explain.

. For the reaction N2(g)+3H2(g)2NH3(g), list the types of bonds that must be broken and the type of bonds that must form for the chemical reaction to take place.

The flasks below illustrated three trials of a reaction between varying amounts of zinc and a constant volume of hydrochloric acid solution of constant concentration. The table gives the initial amount of zinc added and the observation at the conclusion of each reaction. Mass of Zinc Added g Observation at Conclusion of Reaction 6.10 Balloon inflated completely Some unreacted zinc remains 2.37 Balloon inflated completely No zinc remains 0.41 Balloon not inflated completely No zinc remains The reaction produces an aqueous solution of zinc chloride and hydrogen gas. Explain the observed results.

Describe in words the titration of an acid with a base. Be sure to use the terms equivalence point, indicator, and end point correctly.

Reactions represented by the following equations take place in water solutions. Write each molecular equation in total ionic form, then identify spectator ions and write the equations in net ionic form. Solids that do not dissolve are designated by s, gases that do not dissolve are designated by g, and substances that dissolve but do not dissociate appear in blue. a.

QUESTION #1: TOPIC: Solving for a reactant in solution  One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(II) carbonate, in concentrated sulfuric acid. The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper(II) sulfate. Scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: Fe(s) +CuSO4(aq) →Cu(s) +FeSO4(aq) Suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. He adds powdered iron to a 350. mL copper(II) sulfate sample from the plant until no more copper will precipitate. He then washes, dries, and weighs the precipitate, and finds that it has a mass of 93. mg. Calculate the original concentration of copper(II) sulfate in the sample. Round your answer to 2 significant digits.   ? g/L         QUESTION#2: TOPIC: Limiting reactants…
