How many moles of carbon are produced When 1745g of sugar react according to the equation C6H12O6+ H2SO4 to 6C +6H2O

Number of moles of C produced =  58.08 mol

Explanation:

Given data:

Mass of sugar = 1745 g

Moles of C produced = ?

Solution:

Chemical equation:

C₆H₁₂O₆  +   6H₂SO₄    →     6C + 6(H₂SO₄.H₂O)

Number of moles of sugar:

Number of moles = mass/molar mass

Number of moles = 1745 g/180.16 g/mol

Number of moles = 9.68 mol

Now we will compare the moles of C and sugar.

                 C₆H₁₂O₆          :           C

                      1                  :           6

                    9.68              :          6×9.68 = 58.08 mol

Number of moles of C produced =  58.08 mol

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
