This chemistry video tutorial provides an introduction / basic overview explaining how to balance chemical equations such as combustion reactions, synthesis and decomposition reactions, single and double displacement reactions in addition to redox reactions under acidic and basic conditions. This video provides plenty of examples and practice problems that will help you to review for your next test or exam.
Here is a list of equations covered in this video:
1. Combustion Reactions:
Methane + oxygen gas yields carbon dioxide and water OR
CH4 + O2 = CO2 + H2O
Propane: C3H8 + O2 = CO2 + H2O
Ethane: C2H6 + O2 = CO2 + H2O
Ethanol: C2H5OH + O2 = CO2 + H2O
Propanol: C3H7OH + O2 = CO2 + H2O
Benzene: C6H6 + O2 = CO2 + H2O
2. Balancing Synthesis & Decomposition Reactions
N2 + H2 = NH3 (nitrogen gas + oxygen gas yields ammonia)
S8 + O2 = SO3 (sulfur + oxygen gas yields sulfur trioxide)
P4 + Cl2 = PCl3 (phosphorus + chlorine gas yields phosphorus trichloride)
Al(OH)3 + CO2 = Al(HCO3)3 (aluminum hydroxide and carbon dioxide gas yields aluminum bicarbonate)
KClO3 = KCl + O2 (potassium chlorate yields potassium chloride and oxygen gas)
Mg3N2 = Mg + N2 (magnesium nitride yields magnesium and nitrogen gas)
3. Al + CuSO4 = Al2(SO4)3 + Cu (aluminum metal and aqueous copper ii sulfate yields aluminum sulfate and copper metal)
K + FeCl2 = KCl + Fe (potassium metal and iron ii chloride yields aqueous potassium chlorine and iron metal)
Na2S + Cl2 = NaCl + S8 (sodium sulfide reacts with chlorine gas to produce sodium chloride and elemental sulfur)
4. How To Balance Double Replacement Reactions:
NaCl + Pb(NO3)2 = PbCl2 + NaNO3
Aqueous sodium chloride reacts with lead (II) nitrate to produce lead (II) chloride and aqueous sodium nitrate
ZnBr2 + Na3PO4 = Zn3(PO4)2 + NaBr
Zinc bromide reacts with sodium phosphate to produce solid zinc phosphate and sodium bromide
Sn(NO3)4 + K3PO3 = Sn3(PO3)4 + KNO3
Tin (IV) Nitrate and potassium phosphite reacts to produce solid tin (IV) phosphite and potassium nitrate
Balancing Redox Reactions In Acidic, Basic, and Neutral Solutions:
Al + Ni2+ = Ni + Al3+
Zn + ClO- = Cl- + Zn2+ (acidic conditions)
Al + BrO4- = Br- + Al3+ (basic conditions)
