Question

Calculeaza cantitatea de substanta si masa acidului clorhidric(HCl)ce a interactionat cu 39,46g aluminiu.Ce masa de hirogen s-a degajat.

Answer 1

6Hcl+ al->alCl3 +3h2 39.46 g/27(M Al) =1.461. 1.41*6*36.5=320 g=masa hcl. Masa h2=1.41*3*2=8.46 g

Answer 2

6HCl+Al -> AlCl3-3H2
39,46g/27(M Al)=1,41
1,41×6×36,5=320g=masa HCl
M H2=1,41×3×2=8,46g
