Question

6. (0.75 pts) Prepping you for material covered later this quarter - The word equation for the reaction in test #4 is given in the lab handout (see reaction #2). Fill in the (unbalanced) chemical equation for this reaction and include states of matter. Gas is (g), aqueous is (aq), liquid is (l), and solid is (s). + ? Lab #5: Identification of an Unknown Compound - Online Last Updated: 7/28/2022 1 of 7 CHEM&121 - Intro to Chemistry w/Lab Andrewsky - Hybrid Summer 2022 7. (1.25 pts) Prepping you for new material - The word equation for the reaction in test #7 is given in the lab handout (see reaction #3). Fill in the (unbalanced) chemical equation for this reaction and include states of matter. Gas is (g), aqueous is (aq), liquid is (l), and solid is (s). ? 8. (4 pts) Effect of lab errors: Which would be worse: if the unknown solution tested positive in both test #4 and #7 or if it tested negative in both? Explain thoroughly your choice. You will not be given credit without thoroughly explaining your choice.
