Balance each of the following neutralization equations:
a. HNO₃(aq) + Ba(OH)₂(s) → H₂O(l) + Ba(NO₃)₂(aq)
Verified step by step guidance
1
Identify the reactants and products in the equation: HNO₃(aq) + Ba(OH)₂(s) → H₂O(l) + Ba(NO₃)₂(aq).
Write down the number of each type of atom on both sides of the equation to see which are unbalanced.
Balance the equation by adjusting coefficients, starting with the compound that contains the most elements, which is Ba(NO₃)₂.
Balance the hydrogen atoms by ensuring the number of H atoms in HNO₃ and H₂O are equal on both sides.
Finally, check the balance of oxygen atoms and adjust if necessary, ensuring the same number of each type of atom on both sides of the equation.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Neutralization Reaction
A neutralization reaction occurs when an acid reacts with a base to produce water and a salt. In this process, the hydrogen ions (H⁺) from the acid combine with hydroxide ions (OH⁻) from the base to form water (H₂O). The remaining ions form the salt, which in this case is barium nitrate (Ba(NO₃)₂). Understanding this concept is crucial for balancing the equation correctly.

Balancing Chemical Equations
Balancing chemical equations involves ensuring that the number of atoms of each element is the same on both sides of the equation. This is achieved by adjusting the coefficients in front of the compounds. The law of conservation of mass dictates that matter cannot be created or destroyed in a chemical reaction, making balancing essential for accurate representation of the reaction.

Stoichiometry
Stoichiometry is the calculation of reactants and products in chemical reactions based on the balanced equation. It allows chemists to predict the amounts of substances consumed and produced. In the context of the given neutralization reaction, stoichiometry helps determine the correct coefficients needed to balance the equation, ensuring that the proportions of reactants and products are accurately represented.
