Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

Question

### Understanding Hydrates and Their Thermal Decomposition

**Hydrates** are ionic compounds that contain water molecules incorporated into their structure. These water molecules are present in a specific ratio within the ionic compound. For example, **barium chloride dihydrate** has the chemical formula **BaCl₂·2H₂O**, indicating that each unit of BaCl₂ contains two water molecules.

### Experimental Objective

In this experiment, you will determine the final products obtained from heating **BaCl₂·2H₂O**. Depending on the extent of heating, three different sets of products are predicted:

#### Reaction Pathways
1. **Reaction 1:**
\[
\text{BaCl}_2·2\text{H}_2\text{O}_{(s)} \xrightarrow{\text{heat}} \text{BaCl}_2·\text{H}_2\text{O}_{(s)} + \text{H}_2\text{O}_{(g)}
\]

2. **Reaction 2:**
\[
\text{BaCl}_2·2\text{H}_2\text{O}_{(s)} \xrightarrow{\text{heat}} \text{BaCl}_2_{(s)} + 2\text{H}_2\text{O}_{(g)}
\]

3. **Reaction 3:**
\[
\text{BaCl}_2·2\text{H}_2\text{O}_{(s)} \xrightarrow{\text{heat}} \text{BaO}_{(s)} + \text{H}_2\text{O}_{(g)} + 2\text{HCl}_{(g)}
\]

### Theoretical Yield Calculation

**Question:**
If the mass of **BaCl₂·2H₂O** sample subjected to thermal decomposition was **2.526 g**, what is the theoretical yield of **BaCl₂** if **Reaction 2** occurred?

#### Given Data:
- Molar mass of **BaCl₂·2H₂O**: **244.2 g**
- Molar mass of **BaCl₂**: **208.2 g**

### Solution:

1. **Determine moles of BaCl₂·2H₂O**:
\[
\text{Moles of BaCl}_2·2\text{H}_2\text{O} = \
