How the colour changes of silver chloride when it is kept in sunlight An iron nail is kept in copper sulphate solution. The hydrogen and oxygen gas can be obtained from water by (iii) Respiration (iii) Copper (i) Digestion This exothermic process is commonly known as (ii) A3B4 → 3A+B2 Balanced equation of Decomposition reaction (iv) Any of these, 2. (iv) Turns grey, 3. (ii) Excretion On reaction of sodium sulphate with barium chloride, the compound which appear in solution as precipitate is, Combustion reaction in our body takes place in which glucose is burnt to generate energy that we use. Ch 1 Chemical Reactions and Equations MCQ Test 3 Science| Class 10th, Ch 1 Chemical Reactions and Equations MCQ Test 2 Science| Class 10th, Ch 3 Metals and Non-Metals MCQ Test 1 Science| Class 10th. When sulphuric acid is poured over zinc, which of the following gas is formed? This reaction takes place at a temperature of 700°C or at room temperature. (iv) Decomposition of silver chloride by sunlight, 4. Which of the following cannot displace copper from its copper solution ? You have already completed the quiz before. Hence you can not start it again. You must sign in or sign up to start the quiz. (iv) Hydrogen. 3. (i) Exothermic (i) Sulphur di oxide (ii) Endothermic (iv) A2B3 + CD → AD3 + BC Balanced equation of double displacement, 9. (ii) Barium chloride (iii) Turns red (iii) Sulphur tri oxide The reaction used in photography is (i) Thermal decomposition of Silver chloride (ii) Thermal decomposition of Silver bromide (iii) Decomposition of silver bromide by Sunlight (iv) Decomposition of silver chloride by sunlight. (ii) Electrolytic decomposition Although the compound can be found in mineral form, AgBr is typically prepared by the reaction of silver nitrate with an alkali bromide, typically potassium bromide: AgNO 3 (aq) + KBr (aq) → AgBr (s)+ KNO 3 (aq) Although less convenient, the salt can also be prepared directly from its elements. 4. (iii) Decomposition due to sunlight The reaction used in photography is (iii) 2AB+C2 → 2AC+B2 Balanced equation of double displacement On reaction of sodium sulphate with barium chloride, the compound which appear in solution as precipitate is (iii) Decomposition of silver bromide by Sunlight (ii) Oxygen (iii) Barium sulphate (iii) Combination reaction (iv) None, 5. The iron is covered by a brownish substance which is. (i) Iron (i) Copper sulphate Which of the following is correct? (i) Its thermal decomposition (ii) Ferrous sulphate precipitate (ii) Zinc (iv) Silver, 6. Upon exposure to light, the silver bromide crystals are altered to form a latent image. 1. You have to finish following quiz, to start this quiz: The hydrogen and oxygen gas can be obtained from water by, How the colour changes of silver chloride when it is kept in sunlight, An iron nail is kept in copper sulphate solution. The decomposition of silver (II) bromide to produce silver (I) and bromine. The silver bromide crystals are light sensitive. This exothermic process is commonly known as. (ii) Thermal decomposition of Silver bromide (i) 2A+B2 → 2AB Balanced equation of Combination Reaction Chemical processing then turns the latent image into a visible image (Bancroft, 1910). An iron nail is kept in copper sulphate solution. (i) Turns black When sulphuric acid is poured over zinc, which of the following gas is formed? (iv) Circulation, 8. 2Ag(solid)+ Br2(liquid) Conditions: room temperature, light As a result of the reaction of decomposition of silver bromide (i) (AgBr) produces silver (Ag), bromine (Br2) (ii) Turns white The iron is covered by a brownish substance which is Hydrolysis of water is (iii) Magnesium Which of the following cannot displace copper from its copper solution? (i) Sodium chloride (i) Thermal decomposition of Silver chloride Light decomposition reaction/ Photolytic decomposition * The word photolysis can be broken into two parts photo means light and lysis means breaking. Chemical reaction initiated by … (iv) Displacement Reaction, 10. (iv) Sodium sulphate, 7.Combustion reaction in our body takes place in which glucose is burnt to generate energy that we use. The steps in the latent image formation are not completely known (Neblette, 1952).
