Question

Допишіть рівняння реакцій, поставте коефіцієнти S+O2(2 знизу)--> Cu+O2(2 знизу)-->

Answer 1

S + O2 = SO2(реакция соединения )

2Cu + O2 = 2CuO(реакция соединения)

Answer 2

Balancing Chemical Equations

To balance the chemical equation for the reaction provided, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

The unbalanced chemical equation is: S + O2 → Cu + O2

To balance this equation, we'll follow these steps:

1. Count the number of atoms of each element on both sides of the equation. 2. Start by balancing the elements that appear only once on each side of the equation. 3. Finally, balance the remaining elements.

Let's proceed with balancing the given chemical equation.

Balancing the Equation

The balanced chemical equation for the given reaction is: 2S + 3O2 → 2Cu + 2O2

Explanation

The balanced equation is obtained by ensuring that the number of atoms of each element is the same on both sides of the equation. Here's the breakdown of the balanced equation:

- Sulfur (S): 2 atoms on the left side and 2 atoms on the right side. - Oxygen (O): 6 atoms on the left side (2 from S and 4 from O2) and 6 atoms on the right side (2 from Cu and 4 from O2). - Copper (Cu): 2 atoms on the right side.

This balanced equation satisfies the law of conservation of mass, ensuring that the same number of each type of atom is present before and after the reaction.
