Consider the reaction xM + yN → products: This reaction was run 10 times with different volumes of the two reactant solutions and the absorbance was measured. The two solutions are both 1.0 M and the total volume mixed together for all 10 reactions was the same. The reaction trial that had the largest absorbance was the one when 10.5 mL of M were mixed with 2.1 mL of N. What is the value of the coefficient x in the balanced equation? Your answer MUST be entered as an integer.

Chem 1212 Lab Report on electrochemistry
Electrochemistry When electrons transfer between reaction components in a redox reaction, we can harness the motion of the electrons to create a potential. Electrochemistry revolves around the separation of the two half-reactions in a redox reaction and establishing two different electrodes. This might involve physically separating the half-reactions or including a separator, such as a semi-permeable membrane or plastic dividers. With the reactions separated, the electrons will need to flow through the wire connecting...
