Cân bằng phương trình phản ứng:

\(c\text{)}Ba+Cl_2\rightarrow BaCl_2\)

\(d\text{)}FeO+H_2\rightarrow Fe+H_2O\)

\(e\text{)}Al_2O_3+HCl\rightarrow AlCl_3+H_2O\)

\(g\text{)}Na+H_2SO_4\rightarrow Na_2SO_4+H_2\uparrow\)

\(h\text{)}Fe_2O_3+H_2SO_4\rightarrow Fe_2\left(SO_4\right)_3+H_2O\)

Answer 1

c) \(Ba+Cl_2\xrightarrow[]{t^\circ}BaCl_2\)

d) \(FeO+H_2\xrightarrow[]{t^{\circ}}Fe+H_2O\uparrow\)

e) \(Al_2O_3+6HCl\xrightarrow[]{}2AlCl_3+3H_2O\)

g) \(Na+H_2SO_4\text{ (loãng)}\xrightarrow[]{}Na_2SO_4+H_2\uparrow\)

h) \(Fe_2O_3+3H_2SO_4\xrightarrow[]{}Fe_2\left(SO_4\right)_3+3H_2O\)
