1 kg -------------- 1000 g
x Kg ------------- 4251 g
1000 . x = 4251 . 1
1000 x = 4251
x = 4251 / 1000
x = 4.251 Kg
hope this helps !.
I think it’s b
Heat isn’t transferred by sublimation
D is the answer dddddddddd
Correct answer is option E. <span>It is a redox reaction in which Zn is oxidized at the anode, and V is reduced at the cathode.
Reason:
In above reaction, the oxidation state of VO3- is +5, while that of VO2 is +4. Thus there is reduction of V from +5 to +4
In case of Zn, oxidation state of Zn is increased from 0 to +2, Thus process is referred as oxidation. </span>
