per day of a certain industrial waste chemical arrives at a treatment plant settling pond with a volume of . is destroyed by sunlight, and once in the pond it has a half-life of . Calculate the equilibrium concentration of in the pond. Round your answer to significant digits

Hey there!

HCN + CuSO₄ → H₂SO₄ + Cu(CN)₂

Balance CN.

1 on the left, 2 on the right. Add a coefficient of 2 in front of HCN.

2HCN + CuSO₄ → H₂SO₄ + Cu(CN)₂

Balance H.

2 on the left, 2 on the right. Already balanced.

Balance SO₄.

1 on the left, 1 on the right. Already balanced.

Balance Cu.

1 on the left, 1 on the right. Already balanced.

Our final balanced equation:

2HCN + CuSO₄ → H₂SO₄ + Cu(CN)₂

Hope this helps!
