Remember to include roman numerals where appropriate. c) What is the mass of 8 H 2O 144.16 g/mol d) What is the mass of BaCl 2 208. b) What is the mole ratio of barium chloride to water It is 1 to 8. Each cell should include a description of what you observed when the reagents were mixed and a correct chemical formula and name for all solutions that turned cloudy and NR for all solutions that did not react or remained clear. Answer the following questions about the compound BaCl 2 8 H 20 a) What does he dot mean It means joined but not bonded or reacting. Complete the table on the following page. Repeat steps 2-4 for Pb2", Ca?, Fe3+, and Cu2+. When you are completely finished, click on the red disposal bucket to clear the lab. With the last tube add Na2CO and record your observations. Use the next tube but add NaOH, and record your observations. It is used to increase the alkalinity of a mixture, neutralize acids and make sodium salts. Sodium Hydroxide Solution, 0.1M, Chem-Lab is a strong base and is highly caustic. ![]() Use the next tube but add NaCl, and record your observations. Used in laboratory applications in titrations. These lab simulations can be assigned as a hybrid solution to enhance in-lab learning or as a complete lab replacement. Record your observations and discard the tube. Realistic biology and chemistry lab simulations offer an authentic experience that moves learning beyond the classroom. Place a second tube from the blue rack (containing Agt) on the metal stand. Drag this test tube to the red disposal bucket on the right. If the solution remains clear, record NR, for no reaction. Observing our nitrate, it has a white crystalline. Record your observation in the table the following page and write a correct chemical formula and name for the product of the reaction. Experimental Question: How can we experimentally determine the formula of an unknown hydrate, A Testable Prediction: Our unknown hydrate may be a hydrate of copper(II) sulfate, magnesium sulfate, iron(III) chloride, or iron(III) nitrate. You will be able to observe what happens in the window at the top left. With one test tube in the metal stand and four others in the blue rack, click on the Na2S bottle located on the lab bench. ![]() Click on the Divide button on the edge of the lab bench four times to make four additional test tubes containing Ag*. Drag the test tube to the blue test tube rack. ion solution on the shelf to add it to the test tube. Drag a test tube from the box and place it on the metal test tube stand. The lab will open in the Inorganic laboratory 2. Start Virtual ChemLab, select Reactions and Stoichiometry, and then select Names and Formulas of Ionic Compounds from the list of assignments. Transcribed image text: o 2-1: Names and Formulas of Ionic Compounds In this problem, you will go into the virtual laboratory and make a series of ionic compounds containing the cations Ag+, Pb, Cazt, Fe3+, and Cu" observe the reactions and identify the color of the compound formed write the chemical formulas and write the chemical name.
