Natural gas is mostly methane, CHA When 128 grams of methane is burned in the chemical reaction shown below, how many grams of water vapor are produced? CH() +202(g) - CO2(g) + 2H2O(9)
8.00 grams
B
144 grams
C
18.0 grams
288 grams

h

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

it is stable as it is in group 0 which have full outer shells of electrons
