Chemistry is a huge part of how we survive as living things. Just three of the many reasons for this are:
#1#.Our reliance on gaseous Oxygen (#"O"_2#) to breathe. Without it, we would die within a few minutes. Our cells rely on it chemically for processes such as cellular respiration as well as enzymatic activity.
#2#. Our need for water #"H"_2"O"#. Water is another compound which us humans need to consume on a daily basis to continue functioning. We are so reliant on this chemical that our bodies are made up of around #70%# of #"H"_2"O"#.
#3#. Think about the solids that are present in our environment. Your desk, the chair you are sitting on, your phone, a tree, and yourself! These are all examples of solids. If solids (matter in a condensed state) did not exist, then we would probably not exist. The universe would not have planets as we know them (for example), and rocky planets like Earth would not exist at all.
I hope that helps!
