Question

Answer 1

a) \(Mg+2HCl\rightarrow MgCl_2+H_2\uparrow\)

b) \(2Fe+3Cl_2\underrightarrow{t^o}2FeCl_3\)

c) \(2NaOH+H_2SO_4\rightarrow Na_2SO_4+2H_2O\)

d) \(3Fe+2O_2\underrightarrow{t^o}Fe_3O_4\)

Answer 2

-_- haizzz

Answer 3

\(a.Mg+2HCl--->MgCl_2+H_2\)

\(b.2Fe+3Cl_2\overset{t^o}{--->}2FeCl_3\)

\(c.2NaOH+H_2SO_4--->Na_2SO_4+2H_2O\)

\(d.3Fe+2O_2\overset{t^o}{--->}Fe_3O_4\)
