Transition metals can combine with carbon monoxide (CO) to form compounds such as Fe_x_(CO)_y (study question 123). Assume that you combine 0.125 g of nickel with CO and isolate 0.364 g of Ni(CO)_x. What is the value of x? ( A compound composed of iron and carbon monoxide, Fe_x_(CO)_y, is 30.70% iron. What is the empirical formula for the compound?)
