B. Magnesium ribbon burnt in an atmosphere of nitrogen gas to form solid magnesium nitride .
C. Chloride gas is passed in an aqueous potassium iodide solution to form potassium chloride solution and solid iodine .
D. Ethanol is burnt in air to form carbon dioxide , water and release heat.

Answer 1

1.) Fe2O3+ 2Al = 2Fe+ Al2O3

2.) 3Mg + N2 = Mg3N2

3.) 2KI + 3Cl = 2KCl + I 2

4.) C2H5OH + 3O2= 2CO2+3H2O

Answer 2

Answer:Fe2O3+ 2Al = 2Fe+ Al2O3

2.) 3Mg + N2 = Mg3N2

3.) 2KI + 3Cl = 2KCl + I 2

4.) C2H5OH + 3O2= 2CO2+3H2O
