Benzenecarboxylic acid (benzoic acid) and phenylmethanol (benzyl alcohol) are compounds which occur naturally and have a wide range of uses. For example, benzenecarboxylic acid is used as a food preservative and phenylmethanol is used as a solvent.
2-1 Describing Matter Notes. Matter: anything that has mass and takes up space. Chemistry: study of the properties of matter and how matter changes. Substance: single kind of matter that is pure, meaning it always has a specific makeup or composition and a specific set of properties.
PHYSICAL AND CHEMICAL CHANGES LAB. Pre-Lab Discussion. Chemistry is the study of matter and the changes it undergoes. These changes can be divided into 2 classes: physical changes and chemical changes. In a physical change, one or more physical properties.
