Answer to Question #61203 in General Chemistry for Darlene Toremoctha

Question

I have an assignment tho I'm not sure of my answers. just wanna see other source. so here it is: a. bubbles of hydrogen gas and aqueous iron(III) chloride are produced when metallic iron is dropped into hydrochloric acid;(b) solid silver oxide can be heated to give silver and oxygen gas;(d) bubbling chlorine gas through a solution of potassium iodide gives elemental iodine and a solution of potassium chloride;(e) a solution of ammonium chloride reacts with silver nitrate forming aqueous ammonium nitrate and silver chloride precipitate.
for each of these reactions:
i. write a balanced chemical equations;
ii. give an evidence of a chemical reaction; and
iii. identify the type of reaction

I hope for your positive response. I'll be checking my email time to time. Thank you.

Answer 1

a) i. 6HCl + 2Fe = 3H2 + 2FeCl3
ii. released gas, the emergence of bubbles (H2)
iii. single replecement


b) i. 2Ag2O = 4Ag + O2
ii. released gas, the emergence of bubbles (O2)
iii. decomposition


d) i. Cl2 + 2KI = 2KCl + I2
ii. released gas of purple color, odor change (I2)
iii. single replecement


e) i. NH4Cl + AgNO3 = AgCl + NH4NO3
ii. a precipitate is formed (AgCl)
iii. double replecement
