Question

1 multiple choice 2 points
how many reactant molecules are involved in the reaction represented below?
ab₂(s) + 2hj(s) + w₂t(aq) -> 2hbw(s) + atj(aq)
0
1
2
3
4
5

Explanation:

Step1: Identify reactants

Reactants are on the left side of the arrow. The reactants are \(AB_2(s)\), \(2HJ(s)\), and \(W_2T(aq)\).

Step2: Count reactant molecules

There are 3 different reactant species. The coefficient of \(HJ\) (which is 2) represents the number of \(HJ\) molecules, but when counting the number of reactant molecules (species), we consider each unique formula.

Answer:

\(3\)
