Chemistry is the science of matter, especially its chemical reactions, but also its composition, structure and properties. Chemistry deals with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds. Chemistry also involves understanding the properties and interactions of individual atoms and molecules for use in larger-scale applications.

So our first question for the set of problems is answering. What type of compound is water and what type of compound is graphite? So when we're thinking about what kind of compound molecule is we're thinking whether or not it is an inorganic compound or an organic compound. Um, so for the first question, we want to know what type of compound is water. So the molecular formula of water is H two and specifically it is One auction bought it between two hydrogen atoms s so we can represent this molecular formula as this molecular structure. And as you can see, water does not have any carbons that are bonded to another Adam. And so we conclude that water is an inorganic about. So what about graphic? So graphite is actually made up of one single atom carbon, but its molecular structure is very interesting. Um, so graphite is actually made up of, um, single bonds between carbons to make exit gone like structures which end up making thes huge sheets of Carmen um which, as a singular, can have very cool properties. So graphite is something that you'll find in your pencil and the way that it works is that because thes carbon sheets are weakly bonded to other layers of carbon sheets. So that's technically the fourth bond. Um, which I can show here as the stash line. Um And so when you write with your pencil, um, you are basically creating small flakes or layers of graphite, too. Mark your paper. Um and so that's something that's really cool about graphite and going back to the problem. Um, since this is not bonded to any other element besides carbon, we can also conclude that this is an inorganic compound.
