How many grams of CrSO₄ will be made from 25.0 grams each of Zn, K₂Cr₂O₇, and H₂SO₄?
4 Zn + K₂Cr₂O₇ + 7 H₂SO₄ → 4 ZnSO₄ + 2 CrSO₄ + K₂SO₄ + 7 H₂O

Question

How many grams of CrSO₄ will be made from 25.0 grams each of Zn, K₂Cr₂O₇, and H₂SO₄? 4 Zn + K₂Cr₂O₇ + 7 H₂SO₄ → 4 ZnSO₄ + 2 CrSO₄ + K₂SO₄ + 7 H₂O

Quizplus · Accepted Answer

The balanced chemical equation is:4 Zn + K₂Cr₂O₇ + 7 H₂SO₄ → 4 ZnSO₄ + 2 CrSO₄ + K₂SO₄ + 7 H₂OFrom the equation, we can see that 1 mole of K₂Cr₂O₇ reacts with 2 moles of CrSO₄.Therefore, 25.0 grams of K₂Cr₂O₇ will react with 25.0 grams of CrSO₄.
