Final answer:
a) HCl + NaOH → NaCl + H₂O (Balanced equation)
b) H₂CO₃ → H₂O + CO₂ (Balanced equation)
c) HF + NH₃ → NH₄F (Balanced equation)
Step-by-step explanation:
a) HCl + NaOH → NaCl + H₂O: This equation represents a neutralization reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH). It forms sodium chloride (NaCl) and water (H₂O). To balance this equation, one molecule of HCl reacts with one molecule of NaOH to produce one molecule of NaCl and one molecule of H₂O. The balanced equation is already provided.
b) H₂CO₃ → H₂O + CO₂: This equation depicts the decomposition of carbonic acid (H₂CO₃) into water (H₂O) and carbon dioxide (CO₂). To balance the equation, it requires decomposition into two molecules of water and one molecule of carbon dioxide. The balanced equation is H₂CO₃ → H₂O + CO₂.
c) HF + NH₃ → NH₄F: Here, hydrogen fluoride (HF) reacts with ammonia (NH₃) to produce ammonium fluoride (NH₄F). The equation is already balanced as one molecule of HF reacts with one molecule of NH₃ to yield one molecule of NH₄F. Thus, the provided equation is already balanced
