Question

True/false 41 The shape of a molecule influences the amount of radiation that can be absorbed 42 Carbon atom always forms five bonds gas in our dioxide 43 Water vapor is the most abundant greenhouse of carbon dioxide 44. Photosynthesis dramatically reduces the concentration carbon Reforestation has not had significant impact on reducing microwave radiation (low frequency) will cause bonds to vibrate 47 Combustion is the primary source for carbon dioxide production of ozone 48 burning of an alcohol will produce water and carbon dioxide 49 an increase in greenhouse gases directly related to the depletion 50 Some diatomic gases like greenhouse gases The molar mass of ethane is 30 g/mol Electricity is a form of electromagnetic energy 53 _Chemical energy is energy found chemical bonds 54 The energy of the universe is constant 55 4.184 joules equals 1 calorie

Explanation / Answer

answer

41 True

42 False - Carbon has four valence electrons and four valence orbitals - one 2s and three 2p orbital so it only form 4 bonds.

43 True - Greenhouse gases are those that absorb and emit infrared radiation in the wavelength range emitted by Earth

44 True - Photosynthetic organisms play the essential role of helping to keep carbon dioxide levels relatively constant in atmosphear and maintain the earth tempature.

45 False - It can use CO2 in photosynthesis of tree.

46. True

47. True - humen consume fosile fule and combustion happens so it is primery source.
