Maurizia is almost right. Beryllium and aluminum are the only metals known that form true carbides, C 4-, and not acetylides.
Be2C + H2O ===> 2Be(OH)2 + CH4
Al4C3 + H2O ===> 4Al(OH)3 + 3CH4

Metal carbides react with water to form hydroxides and acetylene :
BeC2+2 H2O >> C2H2 + Be(OH)2

Be & Al carbide r hydrolised by water and metane gas is formed as
Be2C + 4H2O-----> 2Be(OH)2 + CH4
AL4C3 + 12H2O-----> 4Al(OH)3 + 3CH4
these cabides contains C4- ion & r called methanides.
Mg & Ca carbide on hydrolysis give Acetylene gas C2H2 contain C2-2 ion
cac2 + 2H2O----> Ca(oh)@ + C2H2...........Clear to all?
