What is the limiting reactant if 8 g of Ba reacts with 2.8g of Al2(SO4)3?

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.

The is a particle with one unit of positive charge a. proton b. positron c. electron d. nucleus awnser quick it is a important science test!

Is 9 correct? and can someone me with 10? it’s due tomorrow, you
