Fe(s) + 2 HCl(aq) - - -> FeCl2(aq) + H2(g) The chloride crystallizes as FeCl2?4 H2O. Exposure to air gradually oxidizes the iron(II) to FeCl3 and Fe2O3. [ [ Oxidizing FeCl2 with Cl2 produces orange-yellow FeCl3, which has metal-nonmetal bonds with covalent character.
Hope it helps but you have to study it yourself to get the answer =)

Hopefully that helps
i also think its zinc. its sorta the odd man out.
Sucrose burned to black, Zinc metal dissolved in HCl
Mg metal burned with bright light, Zinc metal dissolved in HCl
Mg metal burned and produced white/gray powder, Sucrose burned to black
Mg metal burned and produced white/gray powder, Mg metal burned with bright light
I'm thinking b or a. Most likely B though?
Np if I'm wrong I'm sorry :(
was he wrong??^^
B was wrong
a is wrong too
Then Whats The Answer ?
hey guyes i need an answer plz
Mg metal burned and produced white/gray powder, Sucrose burned to black- so its C
