Propane is used as a fuel in most gas grills to cook food on during the warm summer months. when the propane is burned the following reaction takes place:
c3h8(l) + 5o2(g) = 3co2(g) + 4h20(g)
a standard propane tank contains 6804 g of propane. determine how many molecules of carbon dioxide gas are released into the atmosphere with an entire tank of propane is burned. in your answer be sure to: describe the type of chemical reaction the propane undergoes, calculate the number of moles of propane used in the reaction, explain the mole ratio between propane and carbon dioxide in this reaction, calculate the number of moles of carbon dioxide produced, and calculate the number of molecules of carbon dioxide produced.

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.
