HELPP 16.Ned observed an unknown chemical (A) reacting with hydrochloric acid (HCI). The reaction formed
potassium chloride salt (KCI) and another unknown substance (B). Ned wrote down what he knew about
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 (Cl2) 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 water (H2O).
d. None of the above.
