Question

raportul atomic,raportul de mas si masa molară pt CuS04-Sulfat de cupru,H2SO4-acid sulfuric,Al2O3-oxid de aliminiu,KNO3-azotat de potasiu​

Answer 1

Răspuns:

Explicație:

Ra CuSO4=1:2:4

Ra H2SO4=2:1:4

Ra Al2O3=2:3

Ra KNO3=1:1:3

Rm CuSO4=64:32:4*16=64:32:64=2:1:2

Rm H2SO4=2:32:16*4=2:32:64=1:18:32

Rm Al2O3=2*27:3*16 =54:48=27:24

Rm KNO3=39:14:3*16=39:14:48

MCuSO4=64+32+64=160

MH2SO4=2+32+64=98

MAl2O3=54+48=102

MKNO3=39+14+48=101
