Not illustrated. 1904 Excerpt: ...for transferring the energy of the sun to the living animal. The energy of sunlight expended in breaking up the carbon oxide that is absorbed by the leaf is stored up as potential energy in the vegetable tissue, and again set free as heat in the animal body. The sun's energy that is transformed into the chemical energy of carbon compounds that become parts of vegetable tissue is the physical source and foundation of all life. The plant breathes in carbon dioxide; the animal breathes out carbon dioxide. Each carbon particle involved may go through the same cycle of changes again and again, carrying with it on each round the energy necessary for the maintenance of vegetable and animal life. EXERCISES. 1. Assuming that a square meter of leaf will decompose a liter of carbon dioxide per hour, what weight of carbon will be assimilated in an hour by 1,000 trees, each of which has 100,000 leaves, each leaf measuring 25 sq. cm.? 2. 1s Hg(CN)2 a mercurous or a mercuric compound? What is its name? 3. Describe the usual method of preparing chlorine, and write the reaction. Find the percentage of chlorine in the substance that furnishes it. 4. Zinc nitrate and potassium carbonat react as follows: Zn(NO, ), + K2CO3 = ZnCO3 + 2 KNO3. How much Zn(NO3)2 is required to give 103.17 grams of ZnCO3? 5. How much ZnCO3 may be obtained from 156 grams of 6. How much K2CO3 is needed to decompose 75 grams of Zii(NO, )2.? 7. What quantity of potassium nitrate will result? 8. How much KCO, must be used to obtain 54 grams of ZnCO3? 9. How much potassium nitrate will be produced? 10. Why is the term " organic chemistry " less frequently used than formerly? 11. Trace the muscular energy of a carnivorous animal to solar energy as its source. 12. When oxygen is prepared by heatin...
