Need help balancing this chemical reaction equation
Ca(NO3)2+2NaOH>Ca(OH)2+2NaNO3
It looks balanced to me.
Ca(no3)2+2naoh--->2nano3+ca(oh)2
To balance the chemical reaction equation:
Ca(NO3)2 + 2NaOH -> Ca(OH)2 + 2NaNO3
We need to ensure that there are the same number of atoms of each element on both sides of the equation. Here's how you can balance it:
1. Start by counting the number of atoms for each element on both sides of the equation:
On the left side (reactants):
- Calcium (Ca): 1 atom
- Nitrogen (N): 2 atoms
- Oxygen (O): 6 atoms
- Sodium (Na): 2 atoms
- Hydrogen (H): 2 atoms
On the right side (products):
- Calcium (Ca): 1 atom
- Nitrogen (N): 2 atoms
- Oxygen (O): 4 atoms
- Sodium (Na): 2 atoms
- Hydrogen (H): 2 atoms
2. Start by balancing the most complicated formula first. In this case, we'll start with calcium nitrate (Ca(NO3)2).
- To balance the number of calcium atoms, we need one Ca on both sides of the equation.
Ca(NO3)2 + 2NaOH -> Ca(OH)2 + 2NaNO3
- To balance the number of nitrogen atoms, we need two NO3 groups on the left side.
Ca(NO3)2 + 2NaOH -> Ca(OH)2 + 2NaNO3
- To balance the number of oxygen atoms, we need two OH groups on the right side.
Ca(NO3)2 + 2NaOH -> Ca(OH)2 + 2NaNO3
- Finally, we can balance the number of sodium atoms by ensuring that there are two Na atoms on both sides.
Ca(NO3)2 + 2NaOH -> Ca(OH)2 + 2NaNO3
Now, the equation is balanced:
1Ca(NO3)2 + 2NaOH -> 1Ca(OH)2 + 2NaNO3
