36 şar gr magnezyum ve kükürt tepkimeye girdiğinde hangi elementden kaç gr artar

Sagot :

Adargokrans

Mg:24g/mol  S:32g/mol

 

           2Mg              +            S ----------------   Mg2S

 

36/24=1.5 mol       36/32=1.125mol

            1.5/2                    0.75 mol

 

 

1.125-0.75=0.375 mol

 

n=m/MA    ise       m=0.375x32=12 gram S artar

 

 

18 gr Mg artar.
