The balanced chemical equation for this reaction is: CuO + H2 --> Cu + H2O. The molar mass of copper oxide is 79.55 g/mol, and the molar mass of copper is 63.55 g/mol. From this information, you can calculate that 2.54g of copper oxide requires 1.27g of hydrogen to complete the reaction.
What else can I help you with?
How is copper obtained from its pure form?
Copper is mainly obtained through mining of copper ores. The ore is then crushed and ground to release the copper minerals. The copper is then extracted using a process called smelting, which involves heating the ore with a reducing agent to remove the impurities and obtain pure copper metal.
How do you obtain copper sulfate crystals from a mixture of copper sulfate and sand?
To obtain copper sulfate crystals from a mixture with sand, you can dissolve the mixture in water. The copper sulfate will dissolve, while the sand will not. You can then filter the solution to separate the sand from the copper sulfate solution. By evaporating the water from the copper sulfate solution, you can obtain copper sulfate crystals.
What metal reacts with copper oxide to make copper metal?
Carbon can be used to react with copper oxide to form carbon dioxide and copper metal. This reaction involves heating a mixture of copper oxide and carbon in a reduction reaction, where carbon acts as a reducing agent to obtain copper metal.
Which methods is used to obtain pure copper sulphate from impure sample and how?
One method to obtain pure copper sulfate from an impure sample is by recrystallization. In this process, the impure sample is dissolved in water, and then the solution is heated and slowly cooled to allow pure copper sulfate crystals to form. These crystals are then filtered out and dried to obtain the pure compound.
Malachite is naturally occurring from copper carbonate. outline how a sample of copper metal could be obtained from large lumps of malachite in the laboratory?
Malachite is a hydrated copper carbonate - Cu2CO3(OH)2; this compound is thermally decomposed in water, carbon dioxide and cupric oxide.Cupric oxixe may be reduced with hydrogen to copper:CuO + H2 = Cu + H2O
How would you get copper from copper oxide?
you obtain Cu from CuO only by reducing with hydrogen or carbon monooxide: CuO + H2 → Cu + H2O
How do you make CuO crystals?
Copper oxide (CuO) crystals can be made by heating copper (II) nitrate or copper (II) sulfate in the presence of a reducing agent, such as glucose or hydrogen gas. The reaction forms CuO crystals upon cooling. Precise control of temperature and reaction conditions is important to obtain well-defined CuO crystals.
How do you make copper powder?
I dry it with acetone right on the vacuum filter after its been washed. This removes the water and the acetone can be then removed by gentle warming. But depending on your particle sizes you may need the inert atmosphere for it (Nitrogen, Argon) as the fine one can be pyrophoric in air.

Why were tools more difficult to obtain than copper ones?
Copper melts at a lower temperature than iron. Therefore, in order to remove it from the ore in which it is found, and in order to work it, a hotter fire is needed to for iron than for copper. Making a fire hot enough to extract and work iron is more difficult, so iron tools were more difficult to obtain than copper tools.
What process obtain tiny particles copper sulphate from copper?
Crystallization

What can you get from evaporating copper sulphate?
Evaporating a copper sulphate solution you can obtain anhydrous crystals of CuSO4. Increasing the temperature CuSO4 will be thermally dissociated.
How many electrons does hydrogen want to obtain?
Hydrogen wants to obtain one electron to achieve a stable electron configuration similar to the noble gas helium.
How do you get copper in RuneScape?
To obtain Copper you must either trade with other players, buy Copper at the Grand Exchange, or mine it in a mining site with a pickaxe.
