Answer:
The electrical current in electrolysis act as a catalyst driving a reaction in forward direction because when the electric current is allowed to the electrodes, the particles in the solution starts movement towards electrodes. Before this current, the particles inside the solution are static. If a solution contain sodium chloride so when the electrical current is passed. Sodium moves to the negative electrode while chlorine moves towards positive electrode and both the atoms are separated from each other and the reaction is completed.
Isomers have the same molecular formula but they only differ in structure. So, when trans isomer is converted to cis isomer, you would expect a total mass of 25 mg exactly. So, the percent yield would be:
Percent yield = 5 mg/25 mg * 100 = <em>20%</em>
Steps of a scientific investigation include identifying a research question or problem, forming a hypothesis, gathering evidence, analyzing evidence, deciding whether the evidence supports the hypothesis, drawing conclusions, and communicating the results.
