What is the correct formula for copper(II) oxide?Group of answer choicesCuO2Cu2OCuO2CuO2CO2

The formula for crystals of hydrated copper(II) sulfate is CuS*O_{4} * 5H_{2}*O Hydrated copper(II) sulfate is made by reacting copper(II) oxide with dilute sulfuric acid,The overall equation is shown.CuO+H. S*O_{4} + 4H_{3}*O -> CuS*O_{4} * 5H_{3}*OThe crystals are made using the following steps:step 1 50c * m ^ 2 of 0.2mol / d * m ^ 2 dilute sulfuric acid is heated in a beaker. Powdered copper(II) oxide is added until the copper(II) oxide is in excess. Aqueous copper(II) sulfate is formed.step 2The excess copper(II) oxide is separated from the aqueous copper(II) sulfatestep 3The aqueous copper(11) sulfate is heated until a saturated solution is formed.step 4The saturated solution is allowed to cool and crystallise.The crystals are removed and dried.step 5Calculate the maximum mass of copper(II) sulfate crystals, CuS*O_{4} * 5H_{2}*O that can form using the following steps.Calculate the maximum mass of copper(II) sulfate crystals, CuS*O_{4} * 5H_{2}*O that can form usingthe following steps.. Calculate the number of moles of H_{2}*S*O_{4} in 50c * m ^ 3 of 0.2mol / d * m ^ 3 H_{2}*S*O_{4}molDeduce the number of moles of CuS*O_{4} * 5H_{2}*O that can form.mol

7) Copper and sulfuric acid react to form copper (II) sulfate and water and sulfur dioxide.
