What is an example (problem) where we are using a Bronsted Acid/ Base or a Lewis Acid/Base?

Can Bronsted acid/base be in a same problem(chemical reaction equation) as lewis acids/ bases? When would I know to label something as a bronsted acid/base or lewis acid/base?

I'm also confused about this. What is the definition of a Lewis acid/base and Bronsted acid/base? What is the significance of the difference between these terms?

A Bronsted base is just a proton acceptor and a bronsted acid is a proton donor. A Lewis base is an electron pair acceptor and a Lewis base is an electron pair donor. In almost all cases the molecule that is the bronsted base will also contain the molecule that is a lewis base and same for acids.
Example: HF is a bronsted acid becasue it donates the proton, the H is an lewis acid because it accepts the electrons from the base
