Which statement regarding this equation is TRUE? 4Fe (s) + 3O2 (g) —> 2Fe2O3 (s)

There are 2 reactants.
There are 2 reactants.

There are 5 atoms of oxygen on the reactant side.
There are 5 atoms of oxygen on the reactant side.

The coefficient on O2 is 8.
The coefficient on O, 2, is 8.

Iron (III) oxide is a gas.

the answer would be b i believe

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

give me abc and i will get it for u.
