Question

Ce cantitate de hidrogen se consuma pentru a obtine:
a)4 moli H₂Cl
b)12 moli NH₃
c)64 g CH₄

Answer 1

a) H2 + Cl2 = 2HCl

1mol H2.............2moli HCl
x=2mol................4moli HCl

b) N2 + 3H2 = 2NH3

3moli H2..........2moli NH3
x=.....................12 moli NH3
x=3*12/2
x=18 moli H2

c) C + 2H2 = CH4

2 moli H2...................16g CH4
x=...............................64g CH4

x=64*2/16
x=8 moli H2
