(i)what mass of carbon dioxide (in kg) is produced upon the complete combustion of
18.9 l of propane (approximate contents of one 5-gallon tank)? assume that the
density of the liquid propane in the tank is 0.621 g/ml . (hint: begin by writing
a balanced equation for the combustion reaction.)
m=? kg
(ii) a 22.0 - ml sample of an unknown h3po4 solution is titrated with a 0.110 m naoh
solution. the equivalence point is reached when 18.60 ml of naoh solution is added.
what is the concentration of the unknown h3po4 solution? the neutralization reaction is as
follows:
h3po4(aq) + 3naoh(aq) > 3h2o(l) + na3po4(aq)
m=?

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
