Answer 1

Răspuns:

2Fe +3Cl2 =2FeCl3

a)2x56gFe......................2x162,5gFeCl3

20g Fe.............................X

X=20x2x162,5/2x56 =58gFeCl3

b)  2x56gFe........................3x22,4lCl2

    20gFe...............................Y

Y=20x3x22,4/2x56=12l Cl2

c)n=58/56=1,03 moli

Explicație:

A Fe=56

MFeCl3=162,5

1mol de clor are volum de 22,4l

n=m/M
