Question

Какую массу меди можно получить из оксида меди массой 2 тонны,5% Быстрее пожаалуйста

Answer 1

Оксид соединение CuO . На один атом меди в двух тонах соответственно меди к кислороду 1:1  значит рассчитать количество меди  по процентному соотношению или по формуле относительной молярной массы.

Answer 2

Calculating the Mass of Copper from Copper Oxide

To calculate the mass of copper that can be obtained from copper oxide, we can use the stoichiometry of the reaction between copper oxide and elemental carbon.

The balanced chemical equation for the reaction is: 2 CuO + C → 2 Cu + CO2

This equation shows that 2 moles of copper oxide react with 1 mole of carbon to produce 2 moles of copper and 1 mole of carbon dioxide.

Given that the mass of copper oxide is 2 tonnes (2000 kg), we can calculate the mass of copper produced using the molar masses of copper oxide and copper.

The molar mass of CuO (copper oxide) is approximately 79.55 g/mol, and the molar mass of Cu (copper) is approximately 63.55 g/mol.

Using these molar masses, we can calculate the mass of copper produced from 2 tonnes of copper oxide.

Calculation

Using the stoichiometry of the reaction and the molar masses of the substances involved: - 1 mole of CuO (copper oxide) has a mass of approximately 79.55 g. - 1 mole of Cu (copper) has a mass of approximately 63.55 g.

Given that the mass of copper oxide is 2 tonnes (2000 kg), we can calculate the moles of CuO and then the moles of Cu produced.

1. Calculate the moles of CuO: - Moles of CuO = (Mass of CuO) / (Molar mass of CuO) - Moles of CuO = 2000000 g / 79.55 g/mol - Moles of CuO ≈ 25135.44 moles

2. Calculate the moles of Cu produced: - According to the balanced chemical equation, 2 moles of CuO produce 2 moles of Cu. - Moles of Cu = Moles of CuO - Moles of Cu ≈ 25135.44 moles

3. Calculate the mass of Cu produced: - Mass of Cu = Moles of Cu * Molar mass of Cu - Mass of Cu ≈ 25135.44 moles * 63.55 g/mol - Mass of Cu ≈ 1597235.22 g - The mass of copper that can be obtained from 2 tonnes of copper oxide is approximately 1,597,235.22 grams.

Conclusion

Based on the given information, approximately 1,597,235.22 grams of copper can be obtained from 2 tonnes of copper oxide.
