# What are the names and structures of the following compounds? "CO"_2, "C"_6"H"_12"O"_6, "ATP"

${\text{CO}}_{2}$ has one carbon atom and two oxygen atoms, so it is called carbon dioxide. It's a gas you can find anywhere on Earth that has air, and it's why the pH of everyday water open to the air is less than $7$ (it dissolves in water to make some ${\text{H"_2"CO}}_{3}$, an acid in soda).

${\text{C"_6"H"_12"O}}_{6}$ corresponds to many different compounds, but I presume you mean glucose (a six-carbon sugar), which plants make from photosynthesis. It's also made and/or utilized in our bodies, in for example, the citric acid cycle, glycolysis, etc.

The following structure has the name $\alpha$-D-glucopyranose:

It does break open in water, but it exists primarily (99%) as this ringed structure in water.

$\text{ATP}$, or adenosine triphosphate, is often referred to as the energy carrier in the cells of many organisms. It holds three phosphate groups, and essentially releases and re-binds to one or two phosphate groups to transport energy.
