3. The answer is 18 because 12➗4= 3 so 6*3=18
Answer:
2(2)-0=4
Step-by-step explanation:
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,

E°cell , 
0.0-(-1.18)=+1.18V
=+1.18V
The required Standard electrode potential is +1.18V.

Answer:
-15
Step-by-step explanation:
1/-13
The reciprocal is

Because of the law of indices,
We'll have 
= -13.
-1/2
The reciprocal is
1 ÷ -1/2
Because of the law of indices,
We'll have 
= -2
Therefore, the sum would be -13 + (-2) which would be equals to -15.
The first card has to be 25 or less, which is 50% and the next card has to be a single card, which is 1/49. This will give you the answer of 1/98
