Final answer:
The symbol representing a salt is b) KCl, which is an ionic compound formed by the combination of potassium ions (K+) and chloride ions (Cl-). Option B is correct.
Step-by-step explanation:
The symbol that represents a salt among the given options is b) KCl. Salts are formed by the chemical reaction between an acid and a base, resulting in an ionic compound composed of cations (usually, but not always, metal ions) and anions.
In KCl, K+ (potassium ion) and Cl- (chloride ion) come together through ionic bonds to form potassium chloride, which is a classic example of a salt. On the other hand, option a) O₂ is a molecule of oxygen gas, and option c) C₆H₁₂O₆ is glucose, which is a carbohydrate, not a salt. To identify a salt, look for an ionic compound which typically consists of a metal cation and a nonmetal anion.
The symbol that represents a salt is b) KCl.
A salt is an ionic compound formed when a metal reacts with a nonmetal. In this case, potassium (K) is a metal and chlorine (Cl) is a nonmetal. The combination of these two elements forms the ionic compound potassium chloride (KCl).
