Question

Va rog 4 am nevoie de el maine

Answer 1

E2Ox   si   E2Oy;  y= x+2---> E2Ox   si  E2O2+x

4/5= (2A+16x)/((2A+16x+32)--> 2A=128-16x---> A= 64-8X

100g amestec..........................55,56gO
4A+32x+32g.........................32x+32
222,4A= 1422x+1422---> A= 6,4+6,4X


egaland cele doua expresii pentru A , rezulta x=4 si y=6
introducand valorile x,y in orice ecuatie, rezulta A=32g/mol------> S

Oxizii sunt SO2  si SO3.
