Pb(NO)2(aq) +KCl(aq)-> balance reactions
Please follow directions and type your school subject in the indicated box.
what is the polyatomic ion NO? Is that really NO3 ?
To balance the chemical equation Pb(NO)2(aq) + KCl(aq) --> balanced reaction, you need to ensure that the same number of atoms of each element are present on both sides of the equation. Here's how you can balance this equation step-by-step:
1. Start by counting the number of atoms of each element on both sides of the equation.
On the left side, you have 1 Pb (lead), 2 N (nitrogen), 4 O (oxygen) from Pb(NO)2, and 1 K (potassium) and 1 Cl (chlorine) from KCl.
2. Begin balancing by adjusting the coefficients in front of each compound.
Let's start with the least complex compounds, KCl:
Pb(NO)2(aq) + 2KCl(aq) -->
3. Balance the other atoms in the equation, while considering the polyatomic ions as single units.
Now, let's balance the nitrogen (N) and oxygen (O) atoms from Pb(NO)2:
Pb(NO)2(aq) + 2KCl(aq) --> Pb(NO3)2(aq) + 2KCl(aq)
4. Finally, check that all the atoms are balanced.
On the left side:
1 Pb, 2 N, and 6 O (two from NO2 and four from NO3)
On the right side:
1 Pb, 2 N, and 6 O (all from NO3)
Now, all the elements are balanced, and the equation is balanced as well:
Pb(NO)2(aq) + 2KCl(aq) → Pb(NO3)2(aq) + 2KCl(aq)
