Chloe t. followed the procedure of this experiment to determine the empirical formula of a compound of iron (fe) and chlorine (cl). to do so, she added 2.15 g of zn to a solution containing 1.750 g of fe(x)cl(y). after the reaction was complete, she isolated 0.771 g of fe. the mass of cl in the fe(x)cl(y) solution is

Explanation

The sample contains only the atoms of

Thus no matter what natural numbers and are, shall holds.

Recall that zinc is more reactive than iron as seen in the reactivity series;  Adding zinc to the solution would reduce all iron atoms (regardless of the oxidation state, or ) to their elementary form, hence displacing them out of the solution. of iron was obtained and therefore .

Thus

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
