Write the balanced chemical equation, including the physical states, for the reaction that occurs when the test solution reacts with excess sodium sulfide, Na, S. balanced equation:Procedures Experiment: Determine Limiting and Excess Reactants Part 1: Prepare the Test Solution and Test Standards Record all observations for this part in Table 13.1. Take one 50ml, beaker and one 50mL graduated cylinder from the Containers shelf. Measure 20.0mL6M ammonia in the graduated cylinder, recording the exact volume at the meniscus, then transfer to the beaker. Put the used graduated cylinder in the sink. Take a new 50ml graduated cylinder from the Containers shelf. Take 0.4M zinc sulfate from the Materials shelf. Use the graduated cylinder to measure 20.0m/, record the amount, then transfer to the beaker that contains the ammonia solution. Put the used graduated cylinder in the sink. You have now prepared the test solution, Take two test tubes and one 10mL graduated cylinder from the Containers shelf and place them on the workbench. Double-click on the test tubes and label them "test tube standard 1" and "test tube standard 2'. Take 0.1 M copper(II) sulfate from the Materials shelf and measure 6.0m/. into the graduated cylinder. Double-click on the graduated cylinder and record the exact volume at the meniscus. Transfer the liquid to the test tube 1 and record the color of the solution to reference later. Put the graduated cylinder in the sink. Take a new 10ml graduated cylinder from the Containers shelf. Take 0.1M sodium sulfide from the Materials shelf and measure 6.0m, into the graduated cylinder. Double click on the graduated cylinder and record the exact volume at the meniscus. Transfer the liquid to test tube 2 and record the color of the solution to reference later. Put the used graduated cylinder in the sink. Take a new 10ml graduated cylinder from the Containers shelf. Using the 10mL graduated cylinder, measure 2mL of the test solution and pour 24 into each of the two test tubes. Record any color changes and whether a precipitate forms. The reaction should happen fairly quickly. The first test tube shows what an excess of copper(II) sulfate looks like, and the second test tube shows what an excess of sodium sulfide looks like. These are the standards against which to compare other samples. Double click on each test tube and label the tube for reference.Write the balanced chemical equation, including the physical states, for the reaction that occurs when the test solution reacts with excess sodium sulfide, Na, S. balanced
