How many molecules are in 5.50 moles of sulfer dioxide

219 grams of iron (iii) oxide reacts with excess carbon according to the reaction equation shown below. fe2o3 + c → fe + co2 after a scientist performs the chemical reaction they find the actual yield of iron to be 57.4 grams. calculate the percent yield of this chemical reaction.

Iwll give extra points to who gets this for ! what type of reaction is this? ?

Based on the equation and the information in the table, what is the enthalpy of the reaction?
