In this game there will be a grid of atoms of carbon, hydrogen and oxygen. You need to form molecules by arranging the atoms in a particular sequence. For example, one hydrogen, one oxygen and then one hydrogen will form one water molecule. There are 4 types of molecules that you can form: water,...
