Chem A (double) - Complete POGIL (see below)
2019-2020
Date Due
Jan. 9, 2020
Additional Info
- Complete the POGIL activity we started in class -- including the extension at the end--about combustion reactions.
- FOCUS on WRITING WORD EQUATIONS for all of the questions that ask you to make predictions or write reactions. For example, if I were given a chemical such as "aluminum oxide" and told that it "decomposes," and I were asked to write a reaction to describe it, my WORD EQUATION would be: aluminum oxide yields aluminum + oxygen
- If I were given "magnesium reacts with zinc chloride" I would write "magnesium + zinc chloride --> magnesium chloride + zinc" ( a single replacement reaction!)
- The next step is to write the proper chemical formula underneath each word, which is what you learned in Chapter 7. For the first example above, I would write: Al2O3--> Al + O2 (with the numbers as subscripts). Then, to balance it, I would write: 2Al2O3 --> 4Al + 3O2
- We will learn how to balance in class, but if you remember how to do it from an earlier class, feel free to give it a go. YOU SHOULD AT LEAST WRITE THE WORD EQUATION for all of the reactions and write formulas below the words, using the periodic table and your common ion sheet as needed.
