4. Turn on the gas tap. Let the gas flow for thirty seconds. Light the gas at the small hole at arm's length. Adjust the gas tap to make a small flame. 5. Strongly heat the copper oxide until a reaction takes place. ...read more.


5.78 = 1.46g Mole of copper: 5.78 / 64 = 0.0903 Mole of oxygen: 1.46 / 16 = 0.09125 Ratio: Copper : oxygen 0.0903 : 0.09125 1 : 1.0105... 1 : 1.01 Therefore the ratio of copper to oxygen is 1:1. Conclusion: The ratio of copper to oxygen is 1:1. The empirical formula of copper oxide is CuO. 1 ...read more.

  1. Investigation to Identify the Formula of Hydrated Copper Sulphate and in doing so Find ...

    sulfate can result in burning the anhydrous compound of copper (II) sulfate remnant, thus contaminating it with oxygen and altering the mass present in the crucible. This could lead to varying degrees of inaccuracy. * In contrast to burning the anhydrous compound, the heating could have failed to completely remove all the water - i.e.

    Also, after production, the finished product is stocked in inventory, which serves to meet customer demands. The basic structure of mass customization is similar to that of mass production with variety, but there are important differences. Instead of selecting one variety of a product, each customer provides unique information so
