Absorption of carbon dioxide in KOH solution during combustion analysis is:
Correct answer: A. Chemical change.
- A. Chemical change.
- B. Physical change.
- C. Neither chemical nor physical change.
- D. Both physical and chemical.
Explanation
2 KOH + CO₂ → K₂CO₃ + H₂O It is a chemical change because it involves breaking and forming new chemical bonds. Also, CO₂ is chemically transformed into Potassium carbonate(K2CO3) which have different chemical properties.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
