¿Corresponden a equilibrios homogéneos o heterogéneos? y porque ?
- 2 Zn S (s) + 3 O2 (g) → 2 Zn O (s) + 2 SO2(g)
- 2NOC l ( g ) ⇄ 2N O ( g ) + C l 2 ( g )
- Fe2O3 (s)+ 4 H2 (g) → 3 Fe (s) + 4 H2O (g)
- CO ( g ) + C l 2 ( g ) ⇄ COC l 2 ( g )
- 2SO 2 ( g ) + O 2 ( g ) ⇄ 2S O 3 ( g )

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
