if i get 4 % of yield in the experiment of chemical reactions of copper and percent yield. Is there a possibility the experiment wa success?

~in my opinion it was success because ou theoritical yield is below 100 %
~i just need some opinion.

To determine if the experiment was successful, we need to compare the actual yield obtained to the theoretical yield. The theoretical yield is the maximum amount of product that could be obtained based on stoichiometry and other factors. It is typically expressed as a percentage.

In your case, if you obtained a 4% yield, this means you obtained 4% of the theoretical yield. While a low yield could indicate some factors that affected the reaction, it does not necessarily mean the experiment was unsuccessful. It depends on several factors, such as the expected range of yields for that specific reaction and the goals of the experiment.

To make a more informed judgment, you could consider the following:

1. Compare to expected range: Research or consult references to determine the typical range of yields for the specific reaction you conducted. If your 4% yield falls within that range, it may suggest your experiment was successful.

2. Analyze potential limitations: Identify potential factors that could have limited the yield, such as experimental conditions, impurities, or incomplete reactant conversion. Assess if those limitations were within acceptable limits.

3. Evaluate reproducibility: Conduct the experiment multiple times to see if similar yields are obtained consistently. If the yields are consistently low, it may indicate a need for reassessment or optimization of the experimental conditions.

Remember that scientific experiments often involve iterative processes, and even a low yield can provide valuable insights and contribute to scientific understanding.
