Question

Рассчитайте массу металла Q, если его получили из 24г оксида этого металла (QO) содержащего 8% примесей.

Answer 1

Ответ:

CuO+2HCl -> CuCl2+H2O

Zn+2HCl-> ZnCl2+ H2

H + O2 = H2O

2Zn + O2 = 2ZnO

CuO + H2 ==> Cu + H2O

Answer 2

Calculation of the Mass of Metal Q

To calculate the mass of metal Q, we need to determine the amount of metal present in the 24g of the metal oxide (QO) and then subtract the mass of the impurities.

1. Determine the amount of metal in the metal oxide (QO): - The metal oxide (QO) contains 8% impurities. - Therefore, the metal content in the QO is 100% - 8% = 92%. - This means that 92% of the 24g of QO is the metal content.

Calculation: Metal content in QO = 92% of 24g Metal content in QO = 0.92 * 24g

2. Subtract the mass of the impurities: - The mass of the impurities is not provided in the question. - Therefore, we cannot determine the exact mass of the impurities. - However, we can calculate the mass of the metal Q by subtracting the mass of the impurities from the metal content in QO.

Calculation: Mass of metal Q = Metal content in QO - Mass of impurities

Please provide the mass of the impurities so that we can calculate the mass of the metal Q accurately.
