Question

B) Cu CuO → CuSO4 будь ласка​

Answer 1

Ответ:

2Cu+O2=2CuO

CuO+ H2SO4= CuSO4+H2O

Answer 2

Balancing the Chemical Equation

To balance the chemical equation Cu + CuO → CuSO4, we need to ensure that the same number of each type of atom is present on both sides of the equation.

Balancing Steps

1. Count the atoms: - On the left side, we have 1 Cu and 1 O atom from CuO, and 1 Cu from Cu, making a total of 2 Cu and 1 O. - On the right side, we have 1 Cu, 1 S, and 4 O atoms from CuSO4, making a total of 1 Cu, 1 S, and 4 O.

2. Balance the elements: - Start by balancing the metals, then non-metals, and finally oxygen and hydrogen.

3. Balanced Equation: - After balancing, the equation becomes: ``` 2Cu + O2 → 2CuO ```

Conclusion

The balanced chemical equation for the reaction Cu + CuO → CuSO4 is 2Cu + O2 → 2CuO.
