0.105 g of an unknown diprotic acid is titrated with 0.120 m naoh. the first equivalence point occurred at a volume of 7.00 ml of naoh added; the second equivalence point occurred at a volume of 14.07 ml of naoh added. how many moles of naoh were used to reach the second equivalence point in this diprotic acid titration?

How much energy is made when a pice of wood burns. how do you know

How many moles are in 7.2 x 10^23 carbon molecules? (*round to the nearest hundredth and include the unit "mol c" after your number) question 6 options:

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.
