Fe2O3(s) + CO(g) ---> Fe(s) + CO2(g) (Unbalanced) Balance the equation provided above and then utilize this balanced equation to calculate the number of grams of CO that can react with 0.150 kg of Fe2O3.

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)]
