the reaction:
A + HCl → KCl + B
From this information, Ned inferred that unknown substance A was potassium (K) and that unknown
substance B was hydrogen (H2). What is another logical interpretation of this data?
a. A is chlorine (Cl) and B is hydrochloric acid (HCI).
b. A is potassium chloride (KCl) and B is hydrochloric acid (HCI).
c. A is potassium hydroxide (KOH) and B is hydrogen gas (H2).
