I'd like to welcome you, Happiness: to the Chemical Forums.  According to the Forum Rules{click}, we want to see your attempt, so please click on that link, read the contents, and comply with our rules, so we can help you. 

You're going to have to start with the definitions of your terms.  You'll have to compare the images, with the definitions.  We can all look, but there's not much help we can give.  Can you solve any of these?  Can you determine what you're uncertain of?
