Assignment:
Reactions of metals with acids and metal ions.
Question 1. What are the equations for these metals when mixed with 6 M HCl. Ca, Cu, Mg, Fe, Sn, and Zn. (I tried Ca + HCl and got 3 Ca + 6HCl --> 3CaCl2 + 3H2)
Question 2. We have Ca(NO3)2, Cu(NO3)2, FeSO4, Fe(NO3)3, Mg(NO3)2, SnCl4, and Zn(NO3)2. What is the complete equation and net ionic equation when each of these is mixed with Ca, Cu, Fe, Mg, Sn, and Zn. (ex Ca metal is added to Cu(NO3)2)
So there is like 36 outcomes. You don't have to fill out all these, just give me enough of a clue what is going on (examples of each would be helpful)
Question 3. Which of these six metals should be the most reactive toward oxygen? (I think Calcium)
Question 4. Which is more reactive, Fe 2+ or Fe 3+, and why? (i believe Fe 3+ is)
Question 5. What are the reactions of :
Na + H2O-->
Na + O -->
Na + HCl -->
Na + Ca 2+ -->
Question 6. Tell which subtance is oxidized and reduced in each equation as well as the oxidizing and reducing agent.
a) 2Al (s) + 3 Cl2 (g) --> 2AlCl3 (s)
b) 8H+ (aq) + MnO4- (aq) + 5Fe 2+ (aq) --> 5Fe3+ (aq) + Mn 2+ (aq) + 4H2O (L)
c) FeS(s) + 3NO3 - (aq) + 4H+ (aq) --> 3NO(g) + SO4 2- (aq) + Fe 3+ (aq) + 2H2O
Provide complete and step by step solution for the question and show calculations and use formulas.
