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.

that's just how they are

explanation:

you can't control another persons decisions, all you can do is ask that they respect yours. relationships are hard because you have to put the effort into making sure that another person feels seen, heard, and loved. as time goes on, it gets easier, you learn how to do these things without thinking. loving them becomes as easy as breathing, but every relationship will have fights, and sometimes it'll feel like you're drowning, but as long as you can talk it out and compromise, because that's truly what loving another person is, is compromise, then you'll be okay. movies and tv shows have glamorized and romanticized (pardon the pun) what a relationship would be like. real relationships aren't perfectly timed kisses in the rain, zero fights until one big one ends everything, 6 month anniversaries. real relationships are sleepy confused kisses when one person has to leave for work earlier than the other,   real relationships are having small disagreements, real relationships are messy and confusing, real relationships is knowing that even if you're relationship may not last forever and this may not be the person you're going to spend the rest of your life with, that you love them, and you would do anything to see them happy. so yes, relationships are difficult, but so are many other things, relationships can be amazing but also stressful, and not just romantic i'm also talking about platonic relationships (although the primary example here was romantic) sometimes is best to leave friendships behind, so remember, always do whats going to you be happy in the long run.
