Question

Ce cantitate de metan rezulta prin reactia directa dintre carbon si hydrogen , daca s-a folosit hidrogenull obtinut prin reactia dintre 400 g acid clorhidric 36,5% si zinc ?

Answer 1

Zn + 2 HCl ---> ZnCl2 + H2
mf = md*c/100=400*36,5/100 = 146 g HCl
2*36,5 g HCl........2 g H2
146 g HCl..............x g H2
x = 4 g H2
C + 2 H2 ---> CH4
2*2 g H2..........16 g CH4
4 g H2...................x g CH4
x = 16 g CH4
