Presentation Transcript

1. ____ Na + Br2 → NaBr ____ CuCl2 + H2S → CuS + HCl ____ HgO + Cl2 → HgCl + O2 ____ C + H2 → CH4 ____ KClO3  →   KCl  +  O2  ____ S8 + F2 → SF6 ____ BaCl2   +   Na2 SO4 →     NaCl   +   BaSO4

2. SPS2 Students will explore the properties of matter

3. Warm-up: chemical change? (verbal) http://answers.yahoo.com/question/index?qid=20081211161243AAVD87U

4. Writing equations is a way to describe chemicalreactions. And page 362 workbook Example: NiCl 2 (aq) + 2NaOH(aq)  Ni(OH)2 (s) + 2NaCl (aq)

5. Just work for the element(s) behind it

6. A balanced chemical equation has the same number of atoms of each element on both sides of the equation. The balancing process Involves changing coefficients in a reaction.

7. try your balancing act……. add a coefficient to balance out __Mg(s) + O2 (g)  __MgO(s)

8. Li (s) + H2O -- LiOH (aq) + H2 (g) We have 1 Li, 2 H and 1 O and 1 Li, 1 O, 3 H ….. not balanced. 2Li + 2H2O 2LiOH + H2
