Remember that you have to cite your answers. Your professor needs to know where you're getting this information from. Please follow the ACS STYLE GUIDELINES below.
If you're a Chemistry major, start to familiarize yourself with this citation style. In the US, all chemistry citation follows these rules set out by the American Chemical Society.
There is also an ACS Citation Style Guide from Concordia University. This guide breaks things down into the specific types/formats. Very easy to use and highly recommended.
