You work for a company focused on environmental cleanup. Your job is to collect soil samples in the field and bring them back to the lab for analysis. You determine the metals present in the samples, such as lead and iron. You also try

to determine other substances that may be contaminating the soil, such as pesticides. In addition to identifying these

contaminants, you will use additional instrumentation and procedures to quantify them. Select the Two fields of

chemistry listed below that best describe your work.

Environmental chemistry and analytical chemistry

Explanation:

Environmental chemistry is a scientific study of chemical species in the environment as well as the cycle of materials in nature. Broadly speaking, environmental chemistry involves the study of the sources, reactions, transport, and fates of chemical species in the environment.

Analytical chemistry is a branch of chemistry that deals with the development and use of tools and methods to carry out investigation into the nature and composition of chemical substances.

Both environmental chemistry and analytical chemistry are involved when you collect soil samples for the purpose of analysis. A work focused on environmental clean up must first be concerned with the fate of species in the environment (environmental chemistry) as well as the identification of various contaminants in the environment (analytical chemistry). Hence the answer.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
