Matter is classified as a
(1) substance, only
(2) substance or as a mixture of substances
(3) homogenous mixture, only
(4) homogenous mixture or as a heterogeneous mixture
I think the best option is the second option. Matter is classified as a substance or as a mixture of substances. It is a physical substance that occupies space and has mass. Technically, everything we from our eyes is considered as matter.
