In general: "cc -o hello10 hello10.c". This compiles directly from the C source code to an executable.
If there are multiple modules, one typically compiles them into object files first, then links the object files together: "cc hello10.c" creates hello10.o, and then "cc hello10.o other.o ... -o hello10" creates the hello10 executable from the object file hello10.o and other object files.
However, there are most likely scheme-specific include files (for the compile step) and libraries (for the link step) that need to be pulled in. The documentation for your scheme compiler should tell you what those are, and should give example compile lines.
In practice, one will use a make file to orchestrate all that. Again, the documentation should have example make files. It might be a good time to review make syntax and practice how to write make files.
