Complete and balance the following reactions, where applicable. If no reaction occurs, write N.R.
Li + H2O --->
KCI + F2 --->
Au + HNO3 ---->
CI2 + NaF --->
Li + Fe(NO3)3 --->
I would like to know why you're having trouble with these? If would could find the root cause we might be able to remedy the situation. I think all of these are activity series questions.
The halogens replace "down the series"; i.e., F2 will oxidize Cl^- to Cl2; Cl2 will oxidize Br^- to Br2 and Br2 will oxidize I^- to I2.
To complete and balance the reactions, we need to follow a systematic approach. Let's go step by step:
1. Li + H2O --->
First, we need to determine if Lithium (Li) reacts with water (H2O). Lithium is an alkali metal, which has a tendency to react with water vigorously. So, a reaction occurs.
The balanced equation is:
2Li + 2H2O ---> 2LiOH + H2
2. KCI + F2 --->
Potassium chloride (KCI) contains a metal (Potassium) and a non-metal (Chlorine). Fluorine (F2) is a highly reactive non-metal. So, a reaction occurs.
The balanced equation is:
2KCI + F2 ---> 2KF + Cl2
3. Au + HNO3 --->
Gold (Au) is a relatively non-reactive metal. However, Nitric acid (HNO3) is a strong acid and can oxidize certain metals. In this case, a reaction occurs.
The balanced equation is:
3Au + 4HNO3 ---> 3HAu(NO3)4 + 2NO + 2H2O
4. CI2 + NaF --->
Chlorine (CI2) is a highly reactive non-metal, and Sodium Fluoride (NaF) is an ionic compound. Given the reactivity of chlorine, a reaction occurs.
The balanced equation is:
CI2 + 2NaF ---> 2NaCI + F2
5. Li + Fe(NO3)3 --->
Lithium (Li) is an alkali metal, and Iron Nitrate (Fe(NO3)3) is a compound containing a metal (Iron). Considering the reactivity of lithium, a reaction occurs.
The balanced equation is:
6Li + 2Fe(NO3)3 ---> 2Fe + 6LiNO3
I hope this helps! Let me know if you have any further questions.
