(/eoc exam) the solar system moves at the speed of 828,000 km/h. tara writes the following steps to calculate this speed in decameters/second (dm/s). [1 km = 100 dm] step 1: divide 828,000 by 100. step 2: divide the result obtained in step 1 by 60. step 3: divide the result obtained in step 2 by 60. step 4: write the number obtained in step 3 with the unit dm/s. which step is incorrect in the conversion? step 1 step 2 step 3 step 4

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

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
