a. Name the product formed.
b. Write the balanced chemical equation for the reaction.

What is Combination reaction?Give one example with balanced chemical equation

Explain the following chemical reactions and write the balanced chemical equations. Sugar is heated (charred.)

When ethanol is heated at 170^(@)C with conc. H_(2)SO_(4) , it forms an organic compound 'A' and water. The compound 'A' reacts with hydrogen in the presence of nickel to form 'B'. i. Name the compounds A and B. Write the chemical equations of the reactions involved.

An organic compound 'A' having molecular formula C_2H_6O evolves hydrogen gas on treatment with sodium metal and on treatment with red phosphorous and iodind gives compound 'B'. The compound 'B' on treatment with, alcoholic KNC and on subsequent reduction gives compound 'C'. The compound 'C' on treatment with nitrous acid evolves nitrogen gas. Write the balanced chemical equations for all the reactions involved and identify thecompound 'A' 'B' and 'C'.

In which chemical reaction does carbon exhibitvariation of oxidation state from -4 to +4 ? Write balanced chemical reaction.

Explain the following reactions giving their balanced chemical equations: Calcium oxide is mixed with water.

When the solution of sodium carbonate is added to the solution of calcium chloride, a precipitate is formed. a. What is the colour of the precipitate formed? b. Name the precipitate. c. What is the type of the chemical reaction?

Explain the following reactions giving their balanced chemical equations: Lead is added to copper sulphate solution.
