Question

Which element is being oxidized in the redox reaction below?

PbO (s) + NH3 (g) yields N2 (g) + Pb (s) + H2O (l)


Pb

O

N

H

Answer 1

it s nitrogen !!

Answer 2

i dont get any of these type of questions.

Which of the following represents the balanced reduction half-reaction from the redox reaction?

Pb + Pd(NO3)2 yields Pb(NO3)2 + Pd
Answer

Pb yields Pd2+ + e-

Pd2+ + 2e- yields Pd

Pb + e- yields Pb

2 Pd2+ + 4 e- yields 2 Pd

Answer 3

In this case one metal atom donates its electrons to another metal ions as result first metal atom oxidises to metal ion and later metal ion get reduced to metal!!!
have u heard metal displacement reaction and electrochemical series!!1

Answer 4

i have no idea
