Answer
The missing reactant in the given chemical reaction is
(barium oxide).
Explanation
## Step 1: Analyze the given chemical equationThe given chemical equation represents a reaction between an unknown reactant (represented by '?') and hydrochloric acid, producing barium chloride and water.## Step 2: Identify the missing reactantTo identify the missing reactant, we need to consider the products formed in the reaction.- Barium chloride (BaCl₂) is a salt containing barium (Ba) and chloride (Cl⁻) ions.- Water (H₂O) is formed when hydrogen ions (H⁺) from the acid react with oxide ions (O²⁻) from a metal oxide.### Therefore, the missing reactant must be a barium-containing metal oxide, represented by
.## Step 3: Write the balanced chemical equationThe balanced chemical equation for the reaction is:### \boxed{\text{BaO} + \text{2HCl} \rightarrow \text{BaCl₂} + \text{H₂O}}
