Double Replacement Reaction
Chemical Equation: Fe(NO3)3 + NaOH → Fe(OH)3 + NaNO3
Balanced Equation: Fe(NO3)3 + 3 NaOH → Fe(OH)3 + 3 Na(NO3)
Single Replacement Reaction
An interesting video about how mixing together hydrochloric acid and zinc can cause an egg to explode while showing a what a single replacement replacement is and explaining how you can tell that a chemical reaction has taken place!
Chemical Equation: HCl + Zn → ZnCl2 + H2
Balanced Equation: 2 HCl + Zn → ZnCl2 + H2
This is what occurs when methane is combined with oxygen gas, the reaction is very interesting and is always a crowd pleaser that shows what combustion reactions yield and can be performed in many different ways- for example like how Ms. K showed us and this way!
Chemical Equation: CH4 + O2 → CO2 + H2O
Balanced Equation: CH4 + 2 O2 → CO2 + 2 H2O
