I have a time limit quiz I’m begging anyone to help please please ASAP please please help please ASAP

Answer below

Explanation:

"2 SO2(g) + O2(g) →  2SO3(g)

The limiting reactant here is oxygen - it is stated that the reaction is run with excess SO2

Looking at the mass of O2 consumed and the stoichiometric ratio, we can calculate the yield:

23.8 g O2 x ( 1 mole O2 / 32 g O2) x ( 2 mole SO3 / mole O2) x (80 g SO3 / mole SO3) =  119 g SO3" wyzant website

Hope this helped! (Also please give me 5 stars)

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

answer: mole of the gas

answer: mole of the gasexplanation:
