what????

Reactivity Series ..

 

[Dashing Cancerian]

Its a Mnemonic for Reactivity series of metals

I knew that but in a different way.... i never asked u about the reactivity series...

 

[Dashing Cancerian]

Reactivity Series ..

but what should i do about it i know that already in an another way....

 

[syed1995]

Reactivity Series ..

I have it remembered with Please Send Cats Monkeys And Zebras In Locked Hired Cages Soon.

i have no idea

 

[Dashing Cancerian]

i have no idea

great,...

what's the answer and why?

Lmao, did someone tag you with that mnemonic ?

 

[syed1995]

great,...

he just gave another mnemonic to revise it from .. just to give others an opportunity to revise whichever they can learn easier .. if you have it memorized the other way .. then you can just ignore that post

A?

i havent studiedd thix topic but still a try.... seee the diode is present on the positive side of the battery from there it will take the electrons and give it to the battery nd the battery will in turn give those electrons to the negative side of the cell nd the whole circuit is closed.
