What is the concentration expressed as parts per million ? 37.9ppm 3?9ppm 3790pprm 3.7ppm The complete combustion of a fossil fuel organic compound will produce? water and carbon monoxide carbon dioxide and oxygen c water and oxygen carbon dioxide and water Which of the following gases is not considered air pollutant ?CO O_3 CO_2 NO_2 SO_2 A diet soda contains 900 calories. How many joules? How many moles of propane (C_3H_8)are in 12 grams of propane?

Explanation / Answer

2) industrial produces highest emmision of carbon dioxide

7) concentration = 0.0379% = 0.0379 /100

in ppm =  0.0379 /100 * 106 = 379 ppm

8) complete combustion proiduces carbon dioxide and water

option d) is corret

9) CO2 is not a air pollutant

10 ) as 1 cal = 4.18 J so

900 cal = 900* 4.18 J = 3762 J

11) as no of moles = given mass / molar mass = 12 / 44 = 0.27 moles of propane
