Question

en la siguente ecuacion quimica destruya la ley de la concervacion de la materia ZnS (s) + 02 (g) = Zn0 (s) + S02 (g)

Answer 1

                        ZnS (s) +    02 (g)        →  Zn0 (s)      +   S02 (g)

                97,4450 g   + 31,9988 g     → 81,3794 g  +   64,0638 g

                                         123.4438 g = 145.4432 g      

                             No se cumple la Ley de la Conservación de la masa

balanceada la ecuacion química:

                     2 ZnS(s)   +   3 O2(g)   →     2 ZnO(s)      +   2 SO2(g)

        2 ( 97,4450 g) +  3(31,9988 g) =  2 ( 81,3794 g ) +  2(64,0638 g)

                    194.89 g +  95.9964 g = 162.7588  +  128.1276 g

                                     290.8864 g = 290.8864 g

                               se cumple la ley de la conservaión de la masa
