Hallo,
hab ein paar Gleichungen bekommen,die ich richtig stellen sollte. hab das schon länger nicht gemacht, hab es aber versucht und wollte fragen, ob sich das jemand ansehen kann,um mir zu sagen, ob das richtig oder falsch ist. Könnte das bitte jemand machen?
4 NO + 2 [mm] O_{2} [/mm] ----> 4 [mm] NO_{2}
[/mm]
[mm] CaCO_{3} [/mm] + 2 HCl ---> [mm] CaCl_{2} [/mm] + [mm] CO_{2} [/mm] + [mm] H_{2}O
[/mm]
2 [mm] Fe_{2}O_{3} [/mm] + 6 CO ----> 2 [mm] Fe_{2} [/mm] + 6 [mm] CO_{2}
[/mm]
[mm] CO_{2} [/mm] + 2 Mg ----> 2 MgO + C
[mm] C_{5}H_{12} [/mm] + 8 [mm] O_{2} [/mm] -----> 5 [mm] CO_{2} [/mm] + 6 [mm] H_{2}O
[/mm]
2 [mm] NH_{3} [/mm] + 6 NO ----> 8 [mm] N_{2} [/mm] + 6 [mm] H_{2}O
[/mm]
[mm] C_{6}H_{12}O_{6} [/mm] + 6 [mm] O_{2} [/mm] ----> 6 [mm] CO_{2} [/mm] + 6 [mm] H_{2}O
[/mm]
[mm] NH_{3} [/mm] + [mm] O_{2} [/mm] -----> NO + [mm] H_{2}O [/mm] (weiss ich nicht)

Hallo zitrone!
> 2 [mm]Fe_{2}O_{3}[/mm] + 6 CO ----> 2 [mm]Fe_{2}[/mm] + 6 [mm]CO_{2}[/mm]
Schreibe rechts besser $4 \ [mm] \text{Fe} [/mm] \ + \ ...$
> 2 [mm]NH_{3}[/mm] + 6 NO ----> 8 [mm]N_{2}[/mm] + 6 [mm]H_{2}O[/mm]
![[notok]](/images/smileys/notok.gif "[notok]") Hier stimmen die Summen der N-Atome nicht.
> [mm]NH_{3}[/mm] + [mm]O_{2}[/mm] -----> NO + [mm]H_{2}O[/mm]
Hier musst Du noch ausgleichen.
