1. Q2:
When blue litmus paper is dipped into a solution it turns red. What do you know about the solution?
A red litmus paper is dipped into a solution it turns blue. What do you know about its solution?
A blue litmus paper remains blue when dipped in a solution. What do you know about it?
What is the Law of Conservation
of Mass? What implications does
it have for chemical reactions?

2. How did it go?

3. Objective: I can balance equations using the Law of Conservation of Mass.

4. SnO2 + 2H2 →Sn + 2H2O
__SnO2 + __H2 →__Sn +__H2O Sn O H Sn O H

5. 2 KClO3 → 2 KCl + 3 O2
__KClO3 →__KCl +__O2 K Cl O K Cl O

6. S F2 → 8 SF6
S8 + F2 → SF6 S F H S F H

7. Carbon Dioxide and Water
Methane + Oxygen 
Carbon Dioxide and Water 
CH4
+ O2
CO2
+ H2O

8. Acid-Base Neutralization
2 NaOH + H2SO4 
Na2SO4 + 2 H2O
NaOH + H2SO4 
Na2SO4 + H2O
Acid-Base Neutralization
