d) Balance the following oxidation-reduction reaction, using the half-reaction method. The reaction occurs in a basic solution. MnO4 + NO2 MnO2 + NO3-

I do need help with this problem. It is multiparty. Thank you!

What kind of electrophysiological experiment is illustrated in the recordings depicted below?

Data Analysis: 1. Create an Absorbance (Y) vs. Concentration (X) graph using data from the six standard solutions above. 2. Perform a linear trendline analysis of your six data points. Display the equation and R² value on the graph with a minimum of 8 decimal places. 3. On the same graph, perform a 2nd order polynomial trendline analysis of your six data points. Display the equation and R² value on the graph with a minimum of 8 decimal places. 4. Turn in your graph as the last page of this report. 5. On a separate piece of paper calculate the concentration of the unknown solution using both the linear and 2nd order polynomial trendline equations (Show all work) 6. Choose the best unknown concentration from #4 above and report it with three significant figures in the unknown data table above.
