Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

Question

**Figure 1: The Process of Producing Biodiesel from Vegetable Oil**

This figure depicts the chemical process of converting triglycerides (oil) into biodiesel using methanol in the presence of a sodium hydroxide (NaOH) catalyst.

### Chemical Reaction:
- **Reactants:**
- Triglyceride (oil): Contains three ester functional groups, each linked to a fatty acid chain represented by "R".
- Methanol (CH₃OH): Three molecules are used in the reaction.

- **Catalyst:**
- Sodium hydroxide (NaOH): Used to accelerate the reaction.

- **Products:**
- Biodiesel: Composed of methyl esters corresponding to the fatty acids.
- Glycerol: Byproduct with three hydroxyl (OH) groups.

### Molecular Weights (MW) and Densities:
- **Triglyceride (oil):**
- MW: 895 g/mol
- Density: 0.895 g/mL

- **Methanol:**
- MW: 32.04 g/mol
- Density: 0.792 g/mL

- **NaOH (catalyst):**
- MW: 30.00 g/mol

- **Biodiesel:**
- MW: 295 g/mol

- **Glycerol:**
- MW: 92.09 g/mol
- Density: 1.26 g/mL

This transesterification process is commonly used in the production of biodiesel from vegetable oils.

Two layers form after the reaction - what is the main component and polarity of each layer? Choose two answers.

- Vegetable oil, nonpolar layer
- Methanol, polar layer
- NaOH, polar layer
- Biodiesel, nonpolar layer
