Matching Reagents and Products in Redox Reactions

To match the reagents and products in the given redox reactions, let's analyze each reaction one by one:

A) Cu + HNO3(razb) → Cu(NO3)2 + H2 - Reagents: Cu, HNO3(razb) - Products: Cu(NO3)2, H2

B) Cu + HNO3(konc) → Cu(NO3)2 + NO + H2O - Reagents: Cu, HNO3(konc) - Products: Cu(NO3)2, NO, H2O

C) NaOCl + KI + H2SO4 → I2 + H2S + K2SO4 + H2O - Reagents: NaOCl, KI, H2SO4 - Products: I2, H2S, K2SO4, H2O

D) KI + H2SO4 → Cu(NO3)2 + NO2 + H2O - Reagents: KI, H2SO4 - Products: Cu(NO3)2, NO2, H2O

E) I2 + NaCl + K2SO4 + H2O - Reagents: I2, NaCl, K2SO4 - Products: No specific products mentioned.

F) K2SO4 + HI - Reagents: K2SO4, HI - Products: No specific products mentioned.
