Good Introduction Books to Chemistry/Chemical Engineering

Orrichio

I am currently a math/chemistry student and I am looking for some good material to read in order to get a general introduction to chemistry/chemical engineering. I am a first year student and I do enjoy textbooks but the texts I have are a bit on the bulky side (weight wise).

Since I know this is a pretty knowledgeable forum I am asking for some guidance to select good introduction books. Equations in the books are preferable.

Thanks in advance,
