Tema la chimie
Scrieti ecuatiile reactilor corespunzatoare acestor transformari , stiind ca se folosesc 1200kg CaCo3 puritate 75%. Calculeaza masa de clorura de calciu respectiv de sulfat de calciu care se obtin
CaCo3 t*c => CaO+Co2 supra 2

Astea am facut pana sa terminat ora acum

CaO(e subliniat)+H2=Ca(OH2)(e subliniat)
Ca(OH)(subliniat e )2+2HCl= >CaCl2(subliniat)+2H2O
Ca(OH)(subliniat)+H2So4= > CaSo4(subliniat)+H2O
Trebuie sa aflam CaCl2=?kg
Si CaSo4=? g sau kg nu mai stiu
A zis sa le rezolvam pe rand cele care am scris in paranteza ca le-am subliniat - imi trebuie tema rapid Dau rep -
