Generally, a three-electrode cell is used in the circuit of controlled-potential electrolysis. The three electrodes are the working electrode, reference electrode, and auxiliary electrode respectively. Match the following symbols to represent three electrodes that are used in the circuit. auxillary electrode; working electrode; auxillary electrode; O reference electrode: reference electrode; auxillary electrode; working electrode; working electrode; working electrode reference electrode reference electrode auxillary electrode

Hi i need help with this question
All changes save 7. When two solutions are mixed, a color change occurs. The data tables show the time between mixing and the color change for two sets of conditions. For Condition One, the solution concentrations were constant and temperature varied. For Condition Two, the temperature was constant and concentrations varied. Condition One: Concentration Time for Temperature (°C) Sample Color to Change 1 10° 36 sec 22° 14 sec Condition Two: Temperature Time for Concentration Sample Color to % Change 1. 100% 15 sec 2. 50% 24 sec Which of these statements is true according to the data? O The reaction rate is greater at 22°C than at 10°C. O Reducing the temperature increases the rate of the reaction. The reaction is affected by changes in temperature not by changes in concentration. O Decreasing the concentration increases the reaction rate. PREVIOUS 17 of 25 NEXT SAVE & EXIT
Experimental Question: "How does_(IV) allect (DV) Independent Variable (IV): The thing you are manipulating/changing. Dependent Variable (DV): The thing you are measuring. Control Variables: The things you wil need to keep the same across al conditions. What might (accidentaly) affect your dependent variabie? Hypothesis:
For the reaction Fe,O3(s) + 3H2(g)-2Fe(s) + 3H,O(g) AH° = 98.8 kJ and AS° = 143 J/K К. AG° for this reaction would be negative at temperatures (above, below) Enter above or below in the first box and enter the temperature in the second box. Assume that AH° and AS° are constant.
