Given the reaction: Cu(s) + 2Ag+ (aq) + Cu²+(aq) + 2Ag(s) Which statement correctly indicates the change that occurs?
1.
One mole of Cu(s) loses a total of 2 moles of electrons.
One mole of Cu(s) gains a total of 1 mole of electrons.
3.
Two moles of Ag (aq) loses a total of 2 moles of electrons
4.
Two moles of Ag (aq) gains a total of 1 mole of electrons

Avariable that is not being directly tested during an experiment should be changed varied experimented controlled
