La neutraluzarea HCl cu Ca(OH)² se obtin 540 g H²O. Calculati masele reactantilor si a produsilor de reactie

Răspuns :

M,HCl= 36,5g/mol
M,Ca(OH)2=74g/mol
M,H2O=18g/mol
M,CaCl2= 111g/mol

2x36,5g......74g.............111g..........2x18g
2HCl  +  Ca(OH)2 ----> CaCl2 +  2H2O
x................y....................z.............540g

x= 540x36,5/18=......................
y=540x74/2x18=.........................
z=540x111/2x18=.....................


finalizeaza calculele  !!!!
