Coord. Science Name: “ A New Language” Date: / / Period: Purpose: The goal of this lesson is to give you practice making sense of some of the “language” of chemistry, and translating chemical names and formulas. Look at each vial and fill in the data in the following table. Name Chemical Formula Description Vial 1 Vial 2 Copper nitrate Vial 3 Small light-blue crystals Vial 4 NaNO3(s) Vial 5 Vial 6 Vial 7 Vial 8 Vial 9 Nitric acid Vial 10 Fine brown powder NaOH(aq) Vial 11 Vial 12 Vial 13 Clear colorless liquid Vial 14 Vial 15 Zinc sulfate Vial 16 Vial 17 Cu(NO3)2(aq) Vial 18 Answer the Following Questions: 1. Examine the contents of the vials and their labels. Write down at least six patterns you notice. Example: Every substance with the word sodium on it also has the symbol Na. 2. The following symbols represent elements. Identify each element: a. Cu b. H c. Zn 3. How would you translate the following words into chemical symbols? a. Sulfate b. Nitrate c. hydroxide 4. Compounds are substances that are made up of more than one element. On your data table, place a “C” next to the number of each vial that contains a compound. 5. What do you think g, l, and s in parentheses stand for? 6. How would you write the chemical formula for ice? 7. What do all the substances labeled (aq) have in common? 8. Get vial 18 from your instructor. Substances from two of the vials have been mixed together in vial 18. Figure out the chemical formulas for the two substances. Putting it Together: 9. Imagine you are in charge of organizing a chemistry stock room. It’s your job to figure out where to store the substances in vials 1 through 17. How would you organize them? Which things would you group together? Homework: Use your data table from today’s activity to answer the following questions. 1. How many elements are represented by the chemical formula for sodium nitrate, NaNO3? Name them. 2. What is the difference between CuSO4(s) and CuSO4(aq)? 3. If table salt, NaCl(s), is dissolved in water, H2O(l), how would you write the chemical formula for the resulting salt water solution? 4. If the simple sugar, glucose, C6H12O6(s), is dissolved with water, H2O(l), how would you write the chemical formula for the resulting sugar water solution?
