Question

Balancing Chemical Equations Practice Balance the following chemical equations. 1. Fe + 02 → Fe2O4 2. Sr+ 0 → Sro I3. Sn + NaOH → Na2SnO2 + H2 4. K + Br2 → KBr class cor 5. CH3 + 02 → CO2 + H2O 1-6 Just 6. Sb + 1 > Sbiz​

Answer 1

Balancing chemical equations is critical for maintaining the law of conservation of mass. The provided chemical equations were balanced by equalizing the number of atoms for each element on both sides. This ensures compliance with the established chemical laws.

Step-by-step explanation:

Chemical equations must be balanced to comply with the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing chemical equations involves making sure that the number of atoms of each element is the same on both sides of the equation. Here are the balanced forms of the provided equations:

• Mg + O₂ → 2MgO
• Ca + 2H₂O → Ca(OH)₂ + H₂
• CuCO₃ + H₂SO₄ → CuSO₄ + H₂O + CO₂
• CaCl₂ + Na₂CO₃ → CaCO₃ + 2NaCl
• C₁₂H₂₂O₁₁ + 12O₂ → 11H₂O + 12CO₂
• Barium chloride + sulphuric acid → barium sulphate + 2 hydrochloric acid
