Oh yes, I get it now! Thank you! Al2O3+Na2CO3 -->2NaAlO2+CO2

Ok, so I have Al2O3 + Na2CO3 -> NaAlO2 + CO2 2 Al, 2 Na, 1 C and 6 O = 1 Na, 1 Al, 1 C, 4O 11=7? Or (+3)*2 (-2)*3 + (+1)*2+ 4 (-2)*3= +1+3 (-2)*2 + 4 (-2)*2 No, that's not it. Or just Al, Na, C, O = Na, Al, C, O 4=4 That's what you mean? If yes then thanks! I'm not so hopeless after all.

Miracles happen, that's without any doubt.

Hi! Hope you'll help me a bit. How to know if there will be Oxygen left or not? And how to solve this? I can solve simple equations these ones are too hard for me: Al2O3 + Na2CO3 -> NaAlO2 + CO2 PCl5 + KNO2 -> NOCl + POCl3 + KCl If I don't understand at the end I'll use equation checker service, but I hope I'll understand)))
