Answer:
The half cell reaction when it used as an anode
H₂(g) → 2 H⁺ + 2 e⁻
Explanation:
Standard hydrogen electrode used as reference electrode & acts as an cathode as well as anode half cell.
The half cell reaction when it used as an anode
H₂(g) → 2 H⁺ + 2 e⁻
(Pressure should be 1 bar , temperature 273 k and concentration of HCl = 1 Molar)
Cell representation
H₂(g) , H⁺(1 M)
The standard electrode potential i.e oxidation as well as reduction = 0.00 V
True. Each contour line on a topographic map represent a certain elevation; the closer they are, the steeper the surface is. All points on a contour line are the same elevation.
According to Arrhenius Theory of acids and bases, an Arrhenius base produces OH-.
Among the four options, (3) LiOH is the correct one because it can separate into Li+ and OH- when being put in water.
Hope this helps~
Answer:
pure research, since applied research is to fulfill a specific goal, while pure research is just for the sake of learning
atoms definitions and I hope this helps
