Iron (III) nitrate reacts with enough sodium iodide to produce iron (II) iodide and other products. For the balanced equation shown below if the reaction of 241.86 grams of Fe(NO3)3 proceeds with a 90% yield, how many grams of iron (II) iodide, FeI2 would be produced?

15) a substance used in manufacturing gasoline consists of finely divided platinum supported on an inert solid. suppose that the platinum is formed by the high temperature reaction between platinum (iv) oxide and hydrogen gas. the other product is water. a) write and balance the equation b) how many grams of hydrogen are needed to produce 1.0 g of platinum metal? c) how many moles of water are produced at the same time? how many grams?
