The required Standard electrode potential is +1.18V.
What is Standard electrode potential?
- The difference in voltage between the cathode and anode is known as the standard cell potential. View Cell Potentials for more details. All of the standard potentials are determined using 1 M solutions, 1 atm, and 298 K.
- The difference between the two electrodes, known as the standard cell potential (Eocell), creates the cell's voltage.
- The equilibrium potential can be measured using the standard electrode potential.
- The potential of a cell under normal state circumstances, which are roughly represented by concentrations of 1 mole per litre, is known as the cell's standard state potential.
Given that,

0.0-(-1.18)=+1.18V
=+1.18V
The required Standard electrode potential is +1.18V.

Question 1:
We can use the rule of exterior angle of triangle, where the exterior angle is equal to the sum of the other 2 interior angles of the triangle except for the adjacent one.
So, we can calculate angle 1 by adding up the 2 given angles.
Angle1 = 62° + 57°
=119°
=answer C.
Question 2:
We can also apply the rule above, but first we have to calculate the remaining angle of the triangle first.
For this, we have to use the angle sum of triangle. All 3 interior angles of triangle should add up to 180°.
Let that remaining angle be x.
X = 180° - 62° - 57°
X=61°
Now we can apply the rule of exterior angle of triangle.
Angle 1 = 62° + 61°
=123°
=answer D.
Answer:
Step-by-step explanation:
<u>Given</u>
- u(x) = x^5 - x^4 + x^2 and v(x) = -x^2
<u>(u/v)(x) = </u>
- (x^5 - x^4 + x^2) /(- x^2) =
- - (x^3 - x^2 + 1) =
- -x^3 + x^2 - 1
Correct option is C
