A piece of magnesium ribbon was heated to redness in an atmosphere of nitrogen and then cooled with water. The gas evolved is
What will happen if aluminium is heated with coke in an atmosphere of nitrogen?
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.
When alumina is heated with carbon in the atmosphere of nitrogen then product formed are
On heating ammonium dichromate, the gas evolved is :
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
The burning of a piece of magnesium ribbon in air is a chemical change. Explain.
A magnesium ribbon is burnt in oxygen to give a white compound X accompanied by emission of light. If the burning ribbon is now placed in an atmosphere of nitrogen, it continues to burn and forms a compound Y. (a) Write the chemical formulae of X and Y. (b) Write a balanced chemical equation, when X is dissolved in water.
A piece of glass is heated to a high temperature and then allowed to cool. If it cracks, a probable reason for this is the following property of glass
