Question
Consider the balanced chemical reaction for the complete combustion reaction of^cyclopropane gas (C_3H_6): a) What compounds are on the left of the reaction (reactants)? Provide the names in alphabetical order (not the formulas. and don't worry about the stoichiometric coefficients for this part), and write the states of each matter ***For example if you have 2 NO_2 (g), you just write nitrogen dioxide in gas state. b) What compounds are on the right of the reaction (products)? Provide the names in alphabetical order (not the formulas, and don't worry about the stoichiometric coefficients for this part), and write the states of each matter ***For example if you have 2 NO_2 (g), you just write nitrogen dioxide in gas state. c) The molar ratio of CO_2: H_2O is Provide the whole number after division, for example for 6:2 you write 3 d) By burning 4.2 g of cyclopropane, moles of CO_2 is produced.Explanation / Answer
(a)
cyclopropane in gas state, oxygen in gas state
(b)
carbon dioxide in gas state, water in liquid state
(c)
1
(d)
Moles of cyclopropane = 4.2/MW = 4.2/42 = 0.1 moles
So, from reaction stoichiometry, moles of CO2 produced = 0.1*3 = 0.3 moles
