Carbon disulfide is prepared by heating sulfur and charcoal. the chemical equation is s2(g)+c(s)↽−−⇀cs2(=9.40 at 900 k how many grams of cs2(g) can be prepared by heating 12.5 mol s2(g) with excess carbon in a 5.30 l reaction vessel held at 900 k until equilibrium is attained?

The amount of carbon sulfide prepared is 859.1724 grams.

Explanation:

To calculate the concentration of , we use the equation:

     .....(1)

We are given:

Moles of = 12.5 moles

Volume of solution = 5.3 L

Putting values in above equation, we get:

For the reaction of sulfur and carbon, the equation follows:

At       2.36      

At      2.36 - x               x

We are given:

Putting values in above equation, we get:

Molarity of = 2.133 M

Volume of solution = 5.30 L

Putting values in equation 1, we get:

Moles of carbon sulfide = 11.3049 mol

Molar mass of carbon sulfide = 76 g/mol

Putting values in above equation, we get:

Hence, the amount of carbon sulfide prepared is 859.1724 grams.

explanation:

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).
