Question 16 Why are carbon and its compounds used as fuels for most applications?
Solution: 10th Ncert Carbon And Compounds Online Carbon and its compounds are used as fuels for most of the applications because they burn in air releasing 10th Ncert Carbon And Compounds Online 10th Ncert Carbon And Compounds Online 10th Ncert Carbon And Compounds Online a lot of heat energy. Question 17 Explain the formation of scum when hard water is treated with soap.
Solution: The precipitate form of scum is formed when soap is used for washing clothes. With hard water, 10th Ncert Carbon And Compounds Online a large amount of soap is wasted in reacting with the calcium and magnesium ions of hard water to form an insoluble precipitate.
The precipitate form formed by the action of hard water on soap, sticks 10th Ncert Carbon And Compounds Online to the clothes being washed and interferes with the cleaning ability of the additional soap. This makes the cleaning of clothes difficult. Question 18 What change will you observe if you test soap with litmus paper red 10th Ncert Carbon And Compounds Online and blue? Solution: Soap is the salt of a strong base NaOH and a weak acid carboxylic acid , 10th Ncert Carbon And Compounds Online 10th Ncert Carbon And Compounds Online so a solution of soap in water is basic in nature.
Being basic, a soap solution turns red litmus paper blue. Question 19 What is hydrogenation? Solution: It is a class of chemical reactions in which the 10th Ncert Carbon And Compounds Online 10th Ncert Carbon And Compounds Online net result is addition of hydrogen H 2 to unsaturated organic compounds such as alkenes, alkynes, etc.
Hydrogenation 10th Ncert Carbon And Compounds Online is widely applied to the processing of vegetable oils and fats. Complete hydrogenation converts unsaturated fatty acids to saturated ones. From the above hydrocarbons C 2 H 2 is an alkyne, whereas C 3 H 6 is an alkene. So, C 3 H 6 and C 2 H 2 will undergo addition reactions.
Question 21 10th Ncert Carbon And Compounds Online 10th Ncert Carbon And Compounds Online Give a test that can be used to differentiate chemically between butter and cooking oil. Solution: Bromine water test 10th Ncert Carbon And Compounds Online 10th Ncert Carbon And Compounds Online can be used to differentiate chemically between butter and cooking oil.
Add bromine water to a little of cooking oil and butter taken in separate test tubes. Decolourising of bromine water by cooking oil unsaturated compound b. Butter 10th Ncert Carbon And Compounds Online saturated compound does not decolourise bromine water. Question 22 Explain the mechanism of the cleaning action of 10th Ncert Carbon And Compounds Online 10th Ncert Carbon And Compounds Online soaps. Solution: We all know that soap is used to remove dirt and and grime from substances.
Generally 10th Ncert Carbon And Compounds Online 10th Ncert Carbon And Compounds Online dirt and grime get stuck because they have an oily component, which is difficult to remove, by plain brushing or washing by water. A soap molecule has two parts, a head and a tail i. A soap 10th Ncert Carbon And Compounds Online molecule has a tadpole like structure shown below.
The organic part is water insoluble but is soluble in 10th Ncert Carbon And Compounds Online organic solvents or in oil or grease. The ionic part is soluble in water, as water is a polar 10th Ncert Carbon And Compounds Online 10th Ncert Carbon And Compounds Online solvent. When soap is added to water in which dirty clothes are soaked, the two parts of the 10th Ncert Carbon And Compounds Online soap molecule dissolve in two different mediums.
When the clothes are rinsed or agitated, the dirt gets pulled 10th Ncert Carbon And Compounds Online 10th Ncert Carbon And Compounds Online out of the clothes, by the soap molecule. In this way soap does its cleaning work on dirty and grimy clothes or hands. The micelle pulls out the dirt and grime more efficiently. Question 23 Would you 10th Ncert Carbon And Compounds Online be able to check if water is hard by using a detergent? Solution: We would not be able to check whether a sample of water is hard by using a detergent, this is because a detergent forms 10th Ncert Carbon And Compounds Online 10th Ncert Carbon And Compounds Online lather easily even with hard water.
Question 24 People use a variety of methods to wash clothes. Solution: It is necessary to shake to get clean clothes because the soap micelles, which entrap oily or greasy particles on the surface of dirty clothes, have to be removed from their surface. When the clothes which are 10th Ncert Carbon And Compounds Online wet by soap solution are beaten, the micelles containing oil or greasy dirt particles get removed from the surface of dirty clothes and go into water and the dirty cloth gets cleaned.
