4- Give any branch of chemistry that is widely studied? Chemistry is the study of matter - anything that has mass and volume. This central science looks into the physical and chemical properties of matter and how these properties are connected to the structure of matter in an atomic or molecular level. The changes involved in matter are also looked at be it physical change or chemical change.

Scientists can learn a great deal about a community's drug use (both legal and illegal) by analyzing the contaminants in wastewater. In a recent study in New York State, chemists measured the concentration of cotinine, a derivative of nicotine that i produced in the liver and excreted in the urine of tobacco users. The chemists found the average cotinine concentrations in the wastewater stream was 1.43 µg/L. a Ι Ι H- b HH H H-C C-N: C=0: TH HH Jonutis/Shutterstock Revell, Introductory Chemistry, 2e, © 2021 W.
