msHCL=20 g
C=36,6%
.................
mH2=?
nH2=?
VH2=?
.............................
HCL+Zn-----> ZnCl (clorat de zinc)+ H2
C=md/ms*100
36,6=md/20*100
md=36,6*20/100
md=7,32 g HCL
pe ecuatie se lucreaza doar cu md!!!
Masa molara pentru HCL= 2+35,5=37.5 g/mol HCL
x=nrde moli adica n= 7,32/37,5=0,19 moli H2
y=masa adica m= 7,32*2/37.5=0,39 g H2
z=volum adica V=7,32*22,4/37,5=4,37 litri H2
