A magnesium ribbon is burnt in the air to give a white compound 'X' 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 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.

When magnesium ribbon burns in air to form magnesium oxide, it is a ………………… reaction.

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.

At higher temperature sodium metal reacts with alumina to give a sodium compound 'X'.'X' is dissolved in water and then carbon dioxide gas is passed through it, a compound 'Y' is formed. The compound 'X' and 'Y' are respectively

Name the type of chemical reaction that occurs when magnesium ribbon is burned in air.

When magnesium burns in air, compounds of magnesium formed are magnesium oxide and:

A compound (A) is used in paints instead of salts of lead.Compound(A) is obtained when a white compound (B) is strongly heated . Compound (B) is insoluble in water but dissolves in sodium hydroxide forming a solution of compound (C ) the compounds (A) on heating with coke gives a metal (D) and a gas (E) which burns with blue flame . (B) also dissolves in ammonium sulphate solution mixed with ammonium hydroxide. solution of compound (A) in dilute HCl gives a bluish white//white precipitate (F) with excess of (F) with excees of K_(4)[Fe(CN)_(6)] identify (A) to (F) and explain the reactions.

Why should a magnesium ribbon be cleaned before burning in air?

The element A burns in nitrogen to give an ionic compound B. the compound B reacts with water to give C and D. A solution of C becomes milkly on bubbling carbon dioxide. What is the natrue of compound (D)?
