Question

for the following double replacement reaction, choose the correct products.
na₂so₄ + bacl₂ →
nabr + baso₃
2nacl + baso₄
nacl₂ + bas
no reaction

Explanation:

Step1: Analyze the double - replacement reaction

In a double - replacement reaction \(AB + CD
ightarrow AD+CB\). For the reaction \(Na_{2}SO_{4}+BaCl_{2}\), \(A = Na\), \(B=SO_{4}^{2 -}\), \(C = Ba\), \(D = Cl\).

Step2: Write the products

The products should be \(NaCl\) and \(BaSO_{4}\). The balanced chemical equation is \(Na_{2}SO_{4}+BaCl_{2}
ightarrow 2NaCl + BaSO_{4}\downarrow\)

Answer:

2NaCl + BaSO₄
