The value of each assignment and each question is stated in the left margin.</p><p>Read all parts of your assignment carefully, and record your answers in the appropriate places. If you have difficulty with an assignment, go back to the textbook and review the appropriate lesson. Be sure to proofread your answers carefully before submitting your Assignment Booklet.</p><p>(x marks) Lesson 2 Assignment: Half-reactions</p><p>(x mark) Lab—Testing Predictions</p><p>Pre-Lab</p><p>1. Use your knowledge of redox reactions to predict which of the combinations of reactants below will result in a spontaneous reaction. Support your prediction by showing a net ionic equation and describing one observation of reaction you would expect from each spontaneous reaction.</p><p>System Reactant 1 Reactant 2</p><p>1 HCl(aq) Mg(s) 2 NiSO4 (aq) Cu(s) 3 NaOH(aq) I2 (aq 4 Na2Cr2O7 (aq) and SnCl2 (aq) H2SO4(aq)</p><p>5 Co(NO3)2 (aq) Sn (s) 6 CuSO4 (aq) Fe(s)</p><p>(x mark) 2. Design an experiment to test prediction using the following combinations of reactants. Make sure you consider safety aspects when suggesting how these substances should be manipulated, and how waste from the reactions should be disposed of. Include a description of how to perform any diagnostic tests that may be required.</p><p>Answer:</p><p>(x mark) Virtual Investigation</p><p>3.
