Balance each of the following:
- Ca + O2——–> CaO
- NaHCO3——–> Na2CO3+ CO2+ H2O
- C5H12+ O2——–> CO2+ H2O
- Al + O2——–> Al2O3
- Ca(NO3)2+ K3PO4——–> Ca3(PO4)2+ KNO3
- Mg + AlF3——–> MgF2+ Al
- C6H14+ O2——–> CO2+ H2O
- KClO3——–> KCl + O2
- Al(OH)3+ H2SO4——–> Al2(SO4)3+ H2O
- Zn + H2SO4——–> ZnSO4+ H2
The Correct Answer and Explanation is :
Here are the balanced chemical equations:
- Ca + O₂ → CaO
Balanced: 2Ca + O₂ → 2CaO - NaHCO₃ → Na₂CO₃ + CO₂ + H₂O
Balanced: 2NaHCO₃ → Na₂CO₃ + CO₂ + H₂O - C₅H₁₂ + O₂ → CO₂ + H₂O
Balanced: C₅H₁₂ + 8O₂ → 5CO₂ + 6H₂O - Al + O₂ → Al₂O₃
Balanced: 4Al + 3O₂ → 2Al₂O₃ - Ca(NO₃)₂ + K₃PO₄ → Ca₃(PO₄)₂ + KNO₃
Balanced: 3Ca(NO₃)₂ + 2K₃PO₄ → Ca₃(PO₄)₂ + 6KNO₃ - Mg + AlF₃ → MgF₂ + Al
Balanced: 3Mg + 2AlF₃ → 3MgF₂ + 2Al - C₆H₁₄ + O₂ → CO₂ + H₂O
Balanced: 2C₆H₁₄ + 19O₂ → 12CO₂ + 14H₂O - KClO₃ → KCl + O₂
Balanced: 2KClO₃ → 2KCl + 3O₂ - Al(OH)₃ + H₂SO₄ → Al₂(SO₄)₃ + H₂O
Balanced: 2Al(OH)₃ + 3H₂SO₄ → Al₂(SO₄)₃ + 6H₂O - Zn + H₂SO₄ → ZnSO₄ + H₂
Balanced: Zn + H₂SO₄ → ZnSO₄ + H₂
Explanation of Balancing Chemical Equations
Balancing chemical equations is essential because it follows the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Every chemical equation must have the same number of each type of atom on both sides of the equation.
- Identify reactants and products: Each chemical reaction consists of reactants (starting substances) and products (substances formed).
- Count the atoms of each element: Check the number of atoms for each element on both sides of the equation.
- Use coefficients: Coefficients (whole numbers placed before compounds) are used to balance the equation without changing the chemical identity of substances.
- Balance oxygen and hydrogen last: In combustion reactions, balance carbon atoms first, then hydrogen, and finally oxygen.
- Check the final balance: Ensure that the total number of atoms of each element is the same on both sides.
For example, in reaction C₆H₁₄ + O₂ → CO₂ + H₂O, we balance carbon first, then hydrogen, and finally oxygen. Since hydrocarbons combust with oxygen, they always produce carbon dioxide and water.
Balancing chemical equations ensures accurate stoichiometry in chemical reactions, which is crucial in industrial processes, laboratory experiments, and real-world applications like pharmaceuticals, environmental chemistry, and engineering.
Now, I will generate an image representing a balanced chemical equation visually.
Here is the visual representation of a balanced chemical equation. The image illustrates the molecular structures of reactants and products, with color-coded atoms and directional arrows to show the reaction process. Let me know if you need any modifications or further explanations!
