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?

How did it go?

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

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

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

S8 + 24 F2 → 8 SF6 S8 + F2 → SF6 S F H S F H

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

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