Question

In a chemical reaction
K₂Cr₂O₇ + xH₂SO₄ + ySO₂
⟶K₂SO₄ + zCr₂ (SO₄ )₃ + H₂O
the values of x, y, z are
(a) 4, 1, 4 (b) 1, 3, 1
(c) 3, 2, 3 (d) 2, 1, 2

Answer 1

Answer:

c is the answer of question

Answer 2

(b) 1, 3, 1

Explanation:

K₂Cr₂O₇ + xH₂SO₄ + ySO₂ ---> K₂SO₄ + zCr₂ (SO₄ )₃ + H₂O

The balanced equation of the above is:  

K₂Cr₂O₇ + H₂SO₄ + 3SO₂ ---> K₂SO₄ + Cr₂ (SO₄ )₃ + H₂O

So the value of x, y, z is 1, 3, 1.

Option B is the answer.
