What is the maximum mass of chlorine that could be released in the stratosphere by 100 g of Freon-11? c. How many moles of atomic chlorine (CI) correspond to the mass calculated in part b? d. How many atoms of chlorine (CI) correspond to the mass calculated in part b? 13. A solar even is a low tech low cost device for focusing sunlight to cook food. How might solar ovens help mitigate global warming? Which regions of the world would benefit most from using this

Answer 1

4) Green House effect of wates is due to absorbing I IR light. The IR can be abscobed by those a vibrantistry where there is a met dipole moment change. IR active IR active : g. a) Ag - 107 E no of Proton=47 eleckon =47 neuton =60 33 Ag -log no. of Boton = 47 eleckon =47 neukon =62 300, +30H4 1o. a) C. H ₂ OG 1 b) In one day metaboloze 1.omg glucose . So, in one year 365 mg glucose molas mass of glucose = 180 g/mol zema glucose - 0.365 = 0.002 mol So, mols of Coz F0-006 mol mays of co, = 0·2649 has molas mass of NO = (14x2)+6 = 44 g/mol celo F = 137.37 g/mol Chu = 16 g/mol Scanned with CamScanner

- molas mays of ecly F = 137.37 g/mol a mass of el in a mol cel; F = 106.359 º mass Descent of eblcsöne = 77.42% > maximum mass of Chlcome = 77.42 g e moles of ehlcome = 2018 mol a) atoms of chlesine = 1:31x1024 atomy, 37 Every fuel burned by producing green house gases of diffesent type. But in solas even no release of green house gases, so, global Wasming can be redneed Tropical regions receives maximum sunlight & equaton region receives maximum sunlight so, these regsans can use, CS Scanned v CamScanner
