Answer:
In this chemical reaction, KOH is a reactant.
Explanation:
Reactants are those substances which are present on the left side of the reaction. These reactants react with each other to form products. In this chemical reaction, Potassium hydroxide (KOH) reacts with hydrogen bromide (HBr) producing potassium bromide and water molecules. These substances are formed by exchanging their atoms and make chemical bonds with each other.
According to Dalton's Atomic Theory, the <em>Law of Definite Proportion is applied when a compound is always made up by a fixed fraction of its individual elements.</em> This is manifested by the balancing of the reaction.
The reaction for this problem is:
H₂ + Cl₂ → 2 HCl
1 mol of H₂ is needed for every 1 mole of Cl₂. Assuming these are ideal gases, the moles is equal to the volume. So, if equal volumes of the reactants are available, they will produce twice the given volumes of HCl.
