Question

write a balance chemical equation
zinc sulphide + oxygen -> zinc oxide + sulphur dioxide ​

Answer 1

Answer:-

The balanced equation is :-

2ZnS + 3O₂ → 2ZnO + 2SO₂

Explanation:-

Given chemical equation is :-

ZnS + O₂ → ZnO + SO₂

There are many ways to balance a chemical equation like hit and trial method, partial equation method and algebraic method.

In this case, let's use the algebraic method.

Firstly, let's rewrite the equation using letter variables for the coefficients:-

aZnS + bO₂ → cZnO + dSO₂

Now, we will set up a series of simultaneous equation, one for each element :-

=> Zn : a = c

=> S : a = d

=> O : 2b = c + 2d

Let c = 1

Then, a = 1, d = 1, b = 3/2

Now, let's put the value of variables in the chemical equation and solve it :-

=> 1ZnS + 3/2O₂ → 1ZnO + 1SO₂

=> 2(ZnS + 3/2O₂) → 2(ZnO + SO₂)

=> 2ZnS + 3O₂ → 2ZnO + 2SO₂

Hence balanced !!!!
