### Improvement and Evaluation of Copper Oxidation Experimental

the average mass of copper oxide that is normally produced is between 1.82 g and 1.87 g when students perform the experiment which is lower than the theoretical value 2.0g . There is a significant difference between the theoretical and measured values of the mass of copper oxide. In fact the correct mass ratio of the oxygen combined with the

### SOLVED:Question 3 ps Culs 2 AgNOslaa 2 Agls Cu NOahlaql

Then we can go from moles of copper two g of copper multiplying by the molar mass of copper 63.546 g and we get 15.9 g of copper to oxide. That can be created if the reaction goes to completion and consumes all 19.9 g of copper to oxide. But what about the oxygen We also have 2.02g of oxygen hydrogen 2.20 g of hydrogen.
