Balancing Chemical Equations: A Concise Guide
- Balancing chemical equations involves ensuring equal atoms on both sides.
- For a combustion reaction like propane with oxygen, balance carbon, hydrogen, then oxygen.
- Example: 3 carbon atoms need 3 CO2 molecules, 8 hydrogen atoms need 4 H2O molecules, and 10 oxygen atoms need 5 O2 molecules.
- Butane with oxygen requires 4 CO2 and 5 H2O molecules, balanced by multiplying the equation by 2.
- Aluminum with hydrochloric acid needs 2 AlCl3 and 3 H2 molecules for balance.
- Gallium with copper bromide needs 3 Cu and 2 Ga atoms for equilibrium.
- Iodine with fluorine balanced by 2 I2 and 7 F2 molecules.
- Sulfur dioxide with oxygen balanced by 1 SO2 and 2 O2 molecules.
- Sodium with sulfur balanced by 16 Na, 1 S8, and 8 Na2S molecules.
- Sodium phosphate with magnesium chloride balanced by 3 Na3PO4, 2 AlCl3, 6 NaCl, and 3 Mg atoms.
- Potassium sulfate with aluminum chloride balanced by 3 K2SO4, 2 AlCl3, 6 KCl, and 2 Al atoms.
- Ammonia with oxygen balanced by 4 NH3, 5 O2, 4 NO, and 6 H2O molecules.
- Ethanol with oxygen balanced by 2 C2H5OH, 3 O2, 2 CO2, and 3 H2O molecules.
