Q. Are we able to reference journals found on Google Scholar and where can I look for help on doing this?

Yes, you can reference articles and journals found via Google Scholar.

However,  firstly, you will need to follow the link to the original source in order to determine the correct document type, i.e. article, journal, webpage etc.

Then you should use the guidelines in the referencing style you are using, i.e. Cite Them Right Harvard or OSCOLA or APA, to correctly reference the resource that you are using.
