(a) Identify the gasses evolved at the anode and cathode in the above experimental set up.
(b) Name the process that occurs. Why is it called so?
(c) Illustrate the reaction of the process with the help of a chemical equation.

Study the given experimental set-up and answer the following questions. Write the products formed in the above process:

Identify the above process in bacteria and identify part A,B &C:

Sketching and labeling a galvanic cell: Design a galvanic cell that uses the redox reaction Fe(s) + 2Fe^(3+)(aq.) rarr 3Fe^(2+)(aq.) Identify the anode cathode half-reactions and sketch the experimental setup. Label the anode and cathode, indicate the directon of elecron and ion flow, and identify the sign of each elctrode. Strategy: First sepreate the overall cell reaction into anode (oxidation) and cathode (reduction) half-reactions. Then, set up two half-cells that use half-reactions, and connect the half-cells with a conducating wire and a salt bridge.

A brown substance 'X' on heating in air forms a substance 'Y'. When hydrogen gas is passed over heated 'Y', it again changes back into 'X'. (i) Name the substances X and Y. (ii) Name the chemical processes occurring during both the changes. (iii) Write the chemical equations.

(a) Draw the structure of methane by showing sharing of electron between carbon and hydrogen atoms. How will you convert methane into chloroform (CHCl_(3)) by substitution reaction? Explain with the help of chemical equations. (b) Write the name and general formula of a chain of hydrocarbons in which an addition reaction with hydrogen can take place. stating the essential conditions reuqired for an addition reaction to occur, write the chemical equation giving the name of the reactant and the product of such a reaction.

Dry pellets of base 'X' when kept in open absorb moisture and turn sticky. The compound is also formed by chlor-alkali process. Write chemical name and formula of X. Describe chlor-alkali process with balanced chemical equation. Name the type of reaction that occures when X is treated with dilute hydrochloric acid. Write the chemical equation. While diluting an acid, why is it recommended that the acid should be added to water and not water to the acid ?
