The answer is 5 cents. To get this answer you subtract the cost of the pencil from the total cost, and that gives you the price of the eraser.

55 (total cost) - 50 (cost of pencil) = .05 cents (cost of eraser)

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.

Answer:

D) (0,9.5) and (10,1.5)

Step-by-step explanation:

a line of best fit is a line that is drawn through the data points on the scatter plot. Option D is the only answer that draws a linear line through the data points.

Option A makes a short line above the points. if the line is not through the points, it doesn't work

Option B is drawing a positive line (as in it's increasing) and therefore cannot work

Option C draws a line below the points and does not represent the line of best fit for this scatter plot

A pizza is 14 inches in diameter. Each square inch of pizza has 14.04 calories. If each slice contains about 270 calories, how m
mr Goodwill [35]

Answer:

8 slices

Step-by-step explanation:

To answer this question, we first need to know the area covered by the pizza.

Since it is circular in shape, we use the formula for the area of a circle.

Mathematically area of a circle = pi * r^2

Here, we were given the diameter but we know that D = 2r or r = D/2. This shows that the radius would be 14/2 = 7 inches

Now the area of the pizza is 22/7 * 7 * 7 = 22 * 7 = 154 square inch

Now we proceed to calculate the amount in calories present in the pizza;

That would be 154 * 14.04 = 2162.16 calories

one slice has 270 calories; The number of slices in 2162.16 calories would be 2162.16/270 = 8.008 which is approximately 8 slices
