30. Which is evidence that the single replacement reaction shown below is also a redox reaction?
Cu + 2AgNO3 ¡æ Cu(NO3)2 + 2Ag (2 points)
The reaction involves the element oxygen.
There are four different elements in the reaction.
Silver is in a compound as a reactant, but is a pure element as a product.
The nitrate ion, NO3−, does not split apart during the reaction.

@saifoo.khan Do you know anyone that could help me with this? I'm supposed to be in a physical science honors class, but I'm being given chem. I have no idea what the answer would be.

NOOOOO! sorry im NO good with chem.

That's fine! Do you know anyone who is though?

The answer is "Silver is in a compound as a reactant, but is a pure element as a product." A Redox reaction is where some elements are reduced, and others are oxidized. The statement shows that silver is reduced.

Okay! Thanks! That was really helpful. :)

Silver is in a compound as a reactant, but is a pure element as a product.

When any metal undergoes Reduction only then it is obtained. As metals form + ions!

anonymous · Answer

Silver so from + to 0 = Reduction

Cu from 0 to +=oxidation

For any reaction to be a redox there must be oxidation and reduction at the same time not just only reduction or oxidation.

Hope that helps
