Remember to include the proper physical states and charges of ions. When writing ions, if acharge number is not "1", place the charge number before the charge sign. If a charge number is "1", donot include the charge number in the formula.Na2S(aq) + ZnSO4(aq)-Molecular:Na,S(aq)+ZnSO4(aq) → ZnS (s) + Na, SO4(aq)Total ionic: Reactants+2Na (aq)+S2-2+2-(aq)+Zn (aq) + SO4 (aq)Products->+ZnS (aq) +2Na (aq)+ SO2 (aq)Net ionic:2+2-Zn (aq)+S (aq)-ZnS (s)S

ssume a highly magnified view of a solution of HCI that allows you to “see” the HCl. Draw this magnified view. If you dropped in a piece of magnesium, the magnesium would disappear, and hydrogen gas would he released. Represent this change using symbols for the elements, and write the balanced equation.
3.86 When a solution is diluted, solvent is added but solute is not. Explain how this idea leads to the equation frequently used in dilution calculations, M1V1= M2V2.
You are given mixtures containing the following compounds. Which compound in each pair could be separated by stirring the solid mixture with water? (a) NaOH and Ca(OH)2 (b) MgC12 and MgF2 (c) AgI and KI (d) NH4Cl and PbCl2
Which symbols are used to indicate solids, liquids, gases, and aqueous solutions in chemical equations?
Write a balanced equation for the reaction of hydroiodic acid, HI, with calcium hydroxide, Ca(OH)2. Then, write the balanced complete ionic equation and the net ionic equation for this neutralization reaction.
The US Environmental Protection Agency (EPA) places limits on the quantities of toxic substances that may be discharged into the sewer system. Limits have been established for a variety of substances, including hexavalent chromium, which is limited to 0.50 mg/L. If an industry is discharging hexavalent chromium as potassium dichromate (K2Cr2O7), what is the maximum permissible molarity of that substance?
What is meant by a strong acid? Are the strong acids also strong electrolytes? Explain.
The units of parts per million (ppm) and parts per billion (ppb) are commonly used by environmental chemists. In general, 1 ppm means 1 part of solute for every 106 parts of solution. Mathematically, by mass: ppm=gsolutegsolution=mgsolutekgsolution In the case of very dilute aqueous solutions, a concentration of 1.0 ppm is equal to 1.0 g of solute per 1.0 mL, which equals 1.0 g solution. Parts per billion is defined in a similar fashion. Calculate the molarity of each of the following aqueous solutions. a. 5.0 ppb Hg in H2O b. 1.0 ppb CHCl3 in H2O c. 10.0 ppm As in H2O d. 0.10 ppm DDT (C14H9Cl5) in H2O
When 10. L of water is added to 3.0 L of 6.0 M H2SO4, what is the molarity of the resulting solution? Assume the volumes are additive.
Three students were asked to find the identity of the metal in a particular sulfate salt. They dissolved a 0.14 72-g sample of the salt in water and treated it with excess barium chloride, resulting in the precipitation of barium sulfate. After the precipitate had been filtered and dried, it weighed 0.2327 g. Each student analyzed the data independently and came to different conclusions. Pat decided that the metal was titanium. Chris thought it was sodium. Randy reported that it was gallium. What formula did each student assign to the sulfate salt? Look for information on the sulfates of gallium, sodium, and titanium in this text and reference books such as the CRC Handbook of Chemistry and Physics. What further tests would you suggest to determine which student is most likely correct?
For each of the following nonmetals, how many electrons will each atom of the nonmetal gain in reacting with a metal? ol type='a'> oxygen chlorine fluorine sulfur nitrogen
Describe some physical and chemical properties of acids and bases. What is meant by a strong acid or base? Are strong acids and bases also strong electrolytes? Give several examples of strong acids and strong bases.
