Consider the reaction between iron (iii) oxide, fe2o3 and carbon monoxide, co. fe2o3 + 3co --> 2fe + 3co2 in the process, 213 g of fe2o3 are reacted with 140 of co. (a) calculate mass of fe formed (b) how many moles of the excess reagent is left at the end of the reaction? pls show me how to calculate this using dimensional analysis : (

How can you use chemical equations to predict the products of the reaction you can carry out?

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
