You can use stoichiometry which is taking the number in from of each substance and using it as a molar ratio(ones that don't have a number actually have a 1 in front
so 2AgNO3 + 1 Zn -> 2 Ag + Zn (NO3)2
The ratio is of moles of Zn to moles of Silver is 1:2 so for every 1 mole of Zn there's 2 moles of Ag
1.3 × 2 = 2.6 moles of Ag are made

a positive and a negative charge are released from rest in vacuum. they move toward each other. as they do:
nika2105 [10]

A positive and a negative charge are released from rest in vacuum. They move toward each other. As they do: A positive potential energy becomes more positive.

For better understanding, lets explain the terms

  • Electrical potential energy is positive  and negative. If positive , it mean that the two charges are of the same type, that is, it is either positive or it is negative when the two charges are of opposite types

  • A Positive potential energy means that work is done on a positive test charge so as to move it from one place to another, this result in the potential energy increases and also the electric potential increases

From the above we can therefore say the answer A positive and a negative charge are released from rest in vacuum. They move toward each other. As they do: A positive potential energy becomes more positive.

is correct
