30. The more reactive halogen elements are able to replace the less reactive halogens from their com-
pounds. For example, if chlorine gas is bubbled
through a potassium iodide solution, elemental
iodine is produced.
Cl2(8) + Kl(aq) →12(s) + KCl(aq)
Calculate the mass of iodine produced when 2.55 g
of chlorine gas is bubbled through an excess amount
of potassium iodide solution.
31. Although we usually think of substances as “burn-
ing” only in oxygen gas, the process of rapid oxida-
tion to produce a flame may also take place in other
strongly oxidizing gases. For example, when iron is
heated and placed in pure chlorine gas, the iron
"burns” according to the following (unbalanced)
reaction:
Fe(s) + Cl2(8) ► FeCl3(s)
How many milligrams of iron(III) chloride result
when 15.5 mg of iron is reacted with an excess of
chlorine gas?
please help. this is due tonight. thanks!
