Based On The Chemical Equation, Use The Drop-down Menu To Choose The Coefficients That Will Balance The Chemical Equation:$ Na_2HPO_4 \rightarrow Na_4P_2O_7 + \square H_2O $
Balancing chemical equations is a crucial aspect of chemistry that helps us understand the stoichiometry of chemical reactions. In this article, we will explore the process of balancing chemical equations, focusing on the given equation: $ Na_2HPO_4 \rightarrow Na_4P_2O_7 + \square H_2O $. We will use the drop-down menu to choose the coefficients that will balance the chemical equation.
Understanding the Chemical Equation
The given chemical equation is:
$ Na_2HPO_4 \rightarrow Na_4P_2O_7 + \square H_2O $
This equation represents the reaction between sodium phosphate ($ Na_2HPO_4 H_2O Na_4P_2O_7 H_2O $).
Balancing the Chemical Equation
To balance the chemical equation, we need to ensure that the number of atoms of each element is the same on both the reactant and product sides. We will start by counting the number of atoms of each element on both sides of the equation.
Counting Atoms on the Reactant Side
- Sodium (Na): 2 atoms
- Phosphorus (P): 1 atom
- Oxygen (O): 4 atoms
- Hydrogen (H): 1 atom
Counting Atoms on the Product Side
- Sodium (Na): 4 atoms
- Phosphorus (P): 2 atoms
- Oxygen (O): 7 atoms
- Hydrogen (H): 2 atoms
Identifying the Imbalance
Comparing the number of atoms on both sides of the equation, we can see that there is an imbalance in the number of sodium, phosphorus, oxygen, and hydrogen atoms.
Balancing Sodium Atoms
To balance the sodium atoms, we need to add a coefficient of 2 in front of $ Na_2HPO_4 $ on the reactant side.
$ 2Na_2HPO_4 \rightarrow Na_4P_2O_7 + \square H_2O $
Balancing Phosphorus Atoms
To balance the phosphorus atoms, we need to add a coefficient of 2 in front of $ Na_4P_2O_7 $ on the product side.
$ 2Na_2HPO_4 \rightarrow 2Na_4P_2O_7 + \square H_2O $
Balancing Oxygen Atoms
To balance the oxygen atoms, we need to add a coefficient of 7 in front of $ H_2O $ on the product side.
$ 2Na_2HPO_4 \rightarrow 2Na_4P_2O_7 + 7H_2O $
Balancing Hydrogen Atoms
To balance the hydrogen atoms, we need to add a coefficient of 7 in front of $ H_2O $ on the product side.
$ 2Na_2HPO_4 \rightarrow 2Na_4P_2O_7 + 7H_2O $
The Balanced Chemical Equation
After balancing the chemical equation, we get:
$ 2Na_2HPO_4 \rightarrow 2Na_4P_2O_7 + 7H_2O $
This is the balanced chemical equation for the reaction between sodium phosphate and water to produce sodium pyrophosphate and water.
Conclusion
Balancing chemical equations is a crucial aspect of chemistry that helps us understand the stoichiometry of chemical reactions. By following the steps outlined in this article, we can balance chemical equations and write them in a way that accurately represents the reaction. The balanced chemical equation for the reaction between sodium phosphate and water to produce sodium pyrophosphate and water is:
$ 2Na_2HPO_4 \rightarrow 2Na_4P_2O_7 + 7H_2O $
