Write balanced equations for the following reactions. a. barium oxide with water

Verified step by step guidance

1. Identify the reactants and products: Barium oxide (BaO) reacts with water (H2O) to form barium hydroxide (Ba(OH)2).
2. Write the unbalanced chemical equation: BaO + H2O → Ba(OH)2.
3. Count the number of each type of atom on both sides of the equation to ensure they are equal.
4. Since there is one barium (Ba), two oxygen (O), and two hydrogen (H) atoms on both sides of the equation, the equation is already balanced.
5. Confirm that the equation is balanced: BaO + H2O → Ba(OH)2.

Key Concepts

Chemical Reactions

A chemical reaction involves the transformation of reactants into products through the breaking and forming of chemical bonds. Understanding the types of reactions, such as synthesis, decomposition, and double displacement, is essential for predicting the products and writing balanced equations.

Balancing Chemical Equations

Balancing chemical equations ensures that the law of conservation of mass is upheld, meaning the number of atoms of each element must be the same on both sides of the equation. This process involves adjusting coefficients in front of compounds to achieve equal numbers of each type of atom.

Hydration Reactions

Hydration reactions occur when a substance reacts with water, often resulting in the formation of a new compound. In the case of barium oxide reacting with water, the product is barium hydroxide, illustrating how metal oxides typically react with water to form hydroxides.
