Dobrý deň, vedel by mi prosím niekto pomôcť s touto úlohou?
Mám rovnicu 2CO g + O2 g ------ 2CO H=-566
Aký dej prebieha? kedže je - tak exotermický?
Ako by sme napísali rovnicu, aby mala H + hodnotu?ň
Čo znamená zmena znamienka v danej rovnici?
Vyzerala by ta rovnica takto? 2CO----2CO + O2 ? ak nie, prečo nie
Dakujem
