A1 : Chemistry is the study of matter and the changes it undergoes. Chemistry is the study of:

1. The structure and properties of the elements of the periodic table
2. How elements combine with one another to form molecules
3. The elemental composition and molecular structure of different materials
4. The rates and manners in which molecules combine and react with one another

A2 : Chemistry is fundamental to the field of chemical engineering as chemical engineers deal with the design, optimization, and operation of chemical processes that involve various chemical reactions. They work with a wide range of materials, from raw feedstocks to finished products. Chemistry knowledge is essential for understanding the properties and behaviors of these materials, including their physical, chemical, and thermal characteristics. This understanding helps in selecting suitable materials for specific applications and designing processes that handle these materials effectively.
