To create voltage in a battery, you need a difference in potential between compounds. what is the difference between the zinc potential of -0.41 volts and the iron potential of 0.76 volts?

  -1.17 volts

Step-by-step explanation:

The difference between "a" and "b" generally means "a-b". Here, the difference between the potentials is ...

  -0.41 V - 0.76 V = -1.17 V

Sometimes, when we talk about the difference, we mean the positive difference. If that is what is intended here, it is 1.17 volts.

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
