What is oxidized and what is reduced in this reaction?

cu(s) + 2agno3(aq) → cu(no3)2(aq) + 2ag(s)

cu is reduced and ag is oxidized.

ag is reduced and cu is oxidized.

no3 is oxidized and cu is reduced.

ag is oxidized and no3 is reduced.

In the given reaction, Cu is oxidized, and Ag is reduced.

Oxidation and reduction are part of the redox reaction.

Oxidation can be described as the loss of electrons and the increase in the oxidation state.

The reduction can be described as the gain of electrons, and the reduction in the oxidation state.

In the given reaction, the oxidation state of Cu, , and Ag in the reactants is 0, -1, and +1 respectively.

The oxidation state of Cu, , and Ag in the products are +1, -1, and 0 respectively.

Since the oxidation state of Cu increases, it is oxidized in the reaction. The decrease in the oxidation state of Ag states the reduction of Ag in the reaction.

mitosis

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
