Question

Punctul c, va rog frumos.​

Answer 1

Răspuns:

Explicație:

avem20/100x200= 40g MgO   , cu M=40g/mol

       80/100x200=  160gCaO           M= 56g/mol

M,MgCl2=95g/mol       M,CaO=111g/mol

40g.................................95g

MgO   +    2HCl-----> MgCl2 + H2O

40g..................................m=95gMgCl2

56g..............................111g

CaO +  2HCl------> CaCl2   +  H2O

160g...........................m=317,1gCaCl2

m,saruri= 95+317,1=........................calculeaza !!!!!
