Plants grow in many different shapes and sizes. Much of their shape depends on an internal structure that is composed of
carbon-containing molecules such as cellulose and lignin. Plants that have a strong internal structure can grow larger than other
plants because their structure can support their size.
Plants obtain the majority of the carbon necessary for building these structural molecules from -
O air
O microorganisms
O soil
O water

Jet A fuel is kerosine based,consisting primarily of CnH2n+2 hydrocarbons, withn: 5 6 to 16, so the carbonhydrogen ratio is close to12. During this flight, how much CO2 was releasedinto the atmosphere? Assume the combustion of thefuel was complete, so all the fuel was burned to formCO2 and H2O. Give both the mass of CO2 produced(in kg and in lbs) and the volume it would occupy at298 K, 1 atm.(b) How much CO2 would be released into the atmosphere if those passengers and crew made the tripinstead, in pairs, in hybrid cars at 40 miles per gallon.Assume the density of the gasoline is 0.75 kg L21andthat carbon and hydrogen dominate the compositionin a ratio of 1:2.

The inhabitants of a small island begin exporting beautiful cloth made from a rare plant that grows only on their island. Seeing how popular the small quantity that they export has been, they steadily raise their prices. A clothing maker from New York, thinking that he can save money by "cutting out the middleman," decides to travel to the small island and buy the cloth himself. Ignorant of the local custom of offering strangers outrageous prices and then negotiating down, the clothing maker accepts (much to everyone's surpise) the initial price of 400 tepizes/m². The price of this cloth in New York is 120 dollars/yard². Part A If the clothing maker bought 500 m² of this fabric, how much money did he lose? Use 1 tepiz = 0.625 dollar and 0.9144 m = 1 yard.
