What will happen if aluminium is heated with coke in an atmosphere of nitrogen?
When alumina is heated with carbon in the atmosphere of nitrogen then product formed are
Write the balanced chemical equations for the following reactions and identify the type of reaction in each case. (a) Iron (III) oxide reacts with aluminium and gives molten iron and aluminium oxide. (b) Magnesium ribbon is burnt in an atmosphere of nitrogen gas to form solid magnesium nitride. (c) Chlorine 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 releases heat.
On heating ammonium dichromate, the gas evolved is
Magnesium is burnt in the atmosphere of dinitrogen. The ash so produced is treated with water. The final products are
On heating ammonium dichromate, the gas evolved is :
A mixture of alumina and coke is heated in a current of nitrogen to about 1800^(@)C and the product obtained treated with water.A gas is evolved.The gas is :
When a piece of sodium metal is dropped in water, hydrogen gas evolved because
A water fern capable of fixing atmospheric nitrogen and used as biofertilizer.
When (NH_4)_2CrO_2O_7 is heated, the gas evolved is
