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,

Mn+2H^+-- > Mn^{+2}+ H_2

E°cell , E\°_{2H^+/H_2}-E\°_{Mn^+2/Mn}

0.0-(-1.18)=+1.18V

=+1.18V

The required Standard electrode potential is +1.18V.

If f(x)=3x-2 and g(x)=x^2+1, find f(g(-1)) and g(f(3))
julsineya [31]

Answer:

f(g(-1))=4

g(f(3))=50

Step-by-step explanation:

We know the definition of both functions: f(x)=3x-2, and g(x)=x^2+1

A) In order to evaluate what f(g(-1)) is, let's first investigate what g(-1) is using the definition for this function:

g(x)=x^2+1\\g(-1)=(-1)^2+1\\g(-1)=1+1\\g(-1)=2

Now let's find what f(2) is using f(x) definition: f(x)=3x-2\\f(2)=3(2)-2\\f(2)=6-2\\f(2)=4

B) In order to evaluate what g(f(3)) is, let's first investigate what f(3) is using the definition for this function:

f(x)=3x-2\\f(3)=3(3)-2\\f(3)=9-2\\f(3)=7

Now let's find what g(7) is using the definition for this function:

g(x)=x^2+1\\g(7)=(7)^2+1\\g(7)=49+1\\g(7)=50

Ended up with 7 7 quarters. Which expression equals the number of dollars Monique spent on the book?
shtirl [24]

Answer:

6.25-1.75

Step-by-step explanation:

Step-by-step explanation:

Monique had 6 dollars. She found 25 cents and then bought a book

25 cents = 0.25 dollars

Total dollar she had= 6 + 0.25= 6.25 dollars

Let x be the cost of a book

She ended up with 7 quarters. Convert quarter into dollars

1 quarter = 0.25 dollars

7 quarters = 7 times 0.25=1.75 dollars

So she ended up with 1.75 dollars

Amount she had at the beginning - the cost of book = amount ended up

Number of dollars spent on the book = Amount she had - amount ended

Number of dollars spent on the book=

6.25-1.75
