Balance each of the following skeleton equations.
A) KCl + Pb(NO3)2 -> PbCl2 + KNO3
I balanced it out like this.
KCl2 + Pb(NO3)2 -> PbCl2 + 2KNO3
After knowing if I've done this correctly, I'll post on my other questions.
You have balanced it by changing subscripts and that is a no, no.
2KCl + Pb(NO3)2 ==> PbCl2 + 2KNO3
Your balanced equation is not correct. Let's go through the steps to balance it correctly.
A) KCl + Pb(NO3)2 -> PbCl2 + KNO3
Step 1: Count the number of each type of atoms on both sides of the equation.
On the left side:
1 potassium (K)
1 chlorine (Cl)
1 lead (Pb)
2 nitrate ions (NO3)
On the right side:
1 lead (Pb)
2 chlorine (Cl)
1 potassium (K)
2 nitrate ions (NO3)
Step 2: Balance the atoms that appear in multiple compounds first.
The number of chlorine (Cl) atoms is already balanced.
The number of potassium (K) atoms is already balanced.
The number of lead (Pb) atoms is already balanced.
Step 3: Balance the remaining atoms.
To balance the nitrate ions (NO3), we can multiply the potassium nitrate (KNO3) on the right side of the equation by 2.
KCl + Pb(NO3)2 -> PbCl2 + 2KNO3
Now the equation is balanced with equal numbers of each atom on both sides.
To determine if your balanced equation is correct, let's go through the steps of balancing the skeleton equation:
A) KCl + Pb(NO3)2 -> PbCl2 + KNO3
1. Count the number of atoms for each element on both sides of the equation:
Left side: 1 K, 1 Cl, 1 Pb, 2 N, 6 O
Right side: 1 Pb, 2 Cl, 1 K, 2 N, 6 O
2. Begin balancing with the elements that are present in the least number of compounds. In this case, we start with Pb.
Pb: There is 1 Pb on the left side and 1 Pb on the right side. It is already balanced.
3. Next, balance the Cl atoms.
Cl: There are 1 Cl on the left side and 2 Cl on the right side. To balance the Cl, we need to put a coefficient of 2 in front of KCl.
2KCl + Pb(NO3)2 -> PbCl2 + KNO3
4. Balance the K atoms.
K: There is 2 K on the left side and 1 K on the right side. To balance the K, we need to put a coefficient of 2 in front of KNO3.
2KCl + Pb(NO3)2 -> PbCl2 + 2KNO3
5. Finally, balance the N atoms.
N: There are 2 N on the left side and 2 N on the right side. It is already balanced.
Now, let's check the number of atoms again:
Left side: 2 K, 2 Cl, 1 Pb, 2 N, 6 O
Right side: 1 Pb, 2 Cl, 2 K, 2 N, 6 O
The equation is now balanced correctly. Therefore, your balanced equation should be:
2KCl + Pb(NO3)2 -> PbCl2 + 2KNO3
