How could you make the reaction Cu(NO3)2 + NaCO3 -- CuCo3+NaNO3 balanced?
You have the formula for sodium carbonate wrong> Na2CO3
The carbonate ion is -2 valence, and Na is +1. Now it will balance.
To balance the chemical equation Cu(NO3)2 + NaCO3 --> CuCO3 + NaNO3, we need to ensure that the number of atoms of each element is the same on both sides of the equation.
Let's break down the equation step by step:
1. Start by counting the number of each type of atom on each side of the equation:
On the left side:
- Copper (Cu): 1 atom
- Nitrogen (N): 2 atoms
- Oxygen (O): 6 atoms
- Sodium (Na): 1 atom
- Carbon (C): 1 atom
On the right side:
- Copper (Cu): 1 atom
- Carbon (C): 1 atom
- Nitrogen (N): 2 atoms
- Oxygen (O): 6 atoms
- Sodium (Na): 1 atom
2. Begin by balancing the atoms that occur in only one compound on each side of the equation. In this case, we'll start with copper (Cu):
On the left side: 1 Cu atom
On the right side: 1 Cu atom
The copper atoms are already balanced.
3. Next, balance the other atoms in the equation, one element at a time. We'll start with nitrogen (N):
On the left side: 2 N atoms
On the right side: 2 N atoms
The nitrogen atoms are already balanced.
4. Now, let's balance the carbon (C) atoms:
On the left side: 1 C atom
On the right side: 1 C atom
The carbon atoms are already balanced.
5. Next, balance the oxygen (O) atoms:
On the left side: 6 O atoms
On the right side: 6 O atoms
The oxygen atoms are already balanced.
6. Finally, balance the sodium (Na) atoms:
On the left side: 1 Na atom
On the right side: 1 Na atom
The sodium atoms are already balanced.
Therefore, the balanced equation is:
Cu(NO3)2 + Na2CO3 --> CuCO3 + 2NaNO3
