The reducing agent is donating electrons and therefore becoming oxidised itself. In this scenario elemental zinc (Zn) is in a reduced state and is oxidised to become Zn2+, in doing so it donates electrons to Fe2+, thereby reducing it to elemental iron (Fe).
The elemental Zinc in solid state is therefore the reducing agent as it reduces Fe2+ to Fe(s).
0 degree Celsius is equal to 272 k
So to convert C to k we need to add 273
To convert K to C we need to subtract 273
Explanation:
It's (D), nuclear fission................
This statement would be best characterized by the law of conservation of momentum—choice C.
