A white coloured substance was placed in sunlight for some time . it was seen that, it turned grey after sometime. now answer the following questions:-
(1.) Why the White coloured substance turned grey?
(2.) what is the role of Sunlight during the reaction?
(3.) give the name and the chemical formula of reactants and products in this reaction.
(4.) what is the name given to such type of reactions?
Answers
1. silver chloride turns grey in sunlight to form silver metal
2. it helps in decomposition to form Cl[gas] & Ag{metal} which is grey in color.
3. 2AgCl(s)in presence of sunlight = 2Ag(s) +Cl2
4. Photolitic decomposition reaction
answer:
White substance X on exposure to sunlight turns grey name the substance x and grey product. The substance X is chloride.
1..Silver chloride, the White coloured substance turned grey in sunlight to create silver metal. When chloride is kept in sun, it decomposes to make chlorine gas and silver metal.
2. It helps in decomposition to create Cl[gas] & Ag which is grey in colour. A chemical change is initiated by absorbing energy within the sort of light. Molecules on the absorption of energy (photon) get into a transient state and are available to decompose.
3. The statement of reactants and products
2AgCl(s)in presence of sunlight = 2Ag(s) +cl2
chlorine gas is evolved.
4. Photo decomposition is the name given to such sorts of reactions.
