Răspuns :
Pai avem asa : [tex] 2H_{2} + O_{2}--> 2H _{2} O[/tex]
Masa Molara = 2*1= 2 g/mol [tex](H _{2})[/tex]
Masa Molara= 2*1+16=18 g/mol [tex](H _{2} O)[/tex]
⇒ x= (12*18)/2 = 108 g ([tex] H_{2}O [/tex]
Masa Molara = 2*1= 2 g/mol [tex](H _{2})[/tex]
Masa Molara= 2*1+16=18 g/mol [tex](H _{2} O)[/tex]
⇒ x= (12*18)/2 = 108 g ([tex] H_{2}O [/tex]
.......................
2H2+O2=2H2O
m H2O=(12*18)/2=108
