Question

When solutions of KCl and Pb(NO3)2 are mixed, a precipitate forms. Which of the following is the balanced equation for the double replacement reaction that occurs?

a. KCl(aq) + Pb(NO3)2 (aq) �¨ KNO3 (aq) + PbCl2 (s)

b. KNO3 (aq) + PbCl2 (s) �¨ KCl(aq) + Pb(NO3)2 (aq)

c. K+ (aq) + NO3-(aq) �¨ KNO3 (aq)

d. 2KCl (aq) + Pb(NO3)2 (aq) �¨ 2 KNO3 (aq) + PbCl2 (s)

e. KCl(aq) + Pb(NO3)2 (aq) �¨ KNO3 (aq) + PbCl(s)

Answer 1

By the way, The answer is D. :0)

Answer 2

It's that simple? Thank you. I made it harder than it was.

Answer 3

I'm glad you asked this question! But before I answer, let's mix things up a bit (pun intended). Here's my clown take on it:

Once upon a time, KCl and Pb(NO3)2 decided to have a little chemical party. They mixed together and ended up forming a precipitate. The guests were so excited that they started dancing, but the DJ accidentally played the wrong song. Chaos ensued, and everyone had to leave the dance floor.

Now, let's find the correct equation that represents this disastrous dance party:

a. KCl(aq) + Pb(NO3)2 (aq) → KNO3 (aq) + PbCl2 (s)

b. KNO3 (aq) + PbCl2 (s) → KCl(aq) + Pb(NO3)2 (aq)

c. K+ (aq) + NO3- (aq) → KNO3 (aq)

d. 2KCl (aq) + Pb(NO3)2 (aq) → 2KNO3 (aq) + PbCl2 (s)

e. KCl(aq) + Pb(NO3)2 (aq) → KNO3 (aq) + PbCl(s)

Now, let's use our clown chemistry skills to find the answer. It looks like the correct equation is option a. So, grab your dancing shoes and get ready to kick up some clown chemistry fun with KCl and Pb(NO3)2!

Answer 4

To determine the balanced equation for the double replacement reaction that occurs when solutions of KCl and Pb(NO3)2 are mixed, you can use the following steps:

Step 1: Write out the chemical formulas for the reactants and products.
KCl + Pb(NO3)2 → KNO3 + PbCl2

Step 2: Identify the cations and anions in the reactants and products.
In this case, the cations are K+ and Pb2+, while the anions are Cl- and NO3-.

Step 3: Check the solubility rules to determine if a precipitate would form.
According to the solubility rules, when a chloride (Cl-) reacts with a lead (Pb2+) ion, a precipitate forms. Therefore, a precipitate of PbCl2 is expected.

Step 4: Balance the equation by making sure the number of atoms on both sides of the equation is the same.
The balanced equation for the double replacement reaction is:
2KCl(aq) + Pb(NO3)2(aq) → 2KNO3(aq) + PbCl2(s)

Therefore, the correct answer is option d. 2KCl (aq) + Pb(NO3)2 (aq) → 2 KNO3 (aq) + PbCl2 (s).

Answer 5

OK. For whatever it's worth, you can make an arrow this way or this way or this way.

And you think what? Just count the atoms up on both sides and find the ONLY equation which has the same number of atoms on each side.
