Let I know the equation with symbol of 'iron2oxide from iron fillings'

Answer 1

FeO is iron(II)oxide. You get it by heating Fe in air (O2)

Answer 2

In my study,I found equation in my book.It is
Fe+C2O4H2=>C2O4Fe +H2
C2O4Fe=>FeO +CO+CO2
I do not understand that.That's right or not.

Answer 3

In your book the reaction between iron and oxalic acid to produce iron(II) oxalate. Then they go through a decomposition of iron(II) oxalate to form iron(II) oxide. This is a two-step synthesis. Bob Pursley gave you the direct one-step process which is far easier to do.

Answer 4

Thanks both.😊😊☺☺
