Question

Classify each of the following as an element, compound, homogeneous mixture, or heterogeneous mixture. Explain. A) sulfur; B) hydrogen peroxide; C) vodka; D) propane; E) air; F) brass; G) blood; H) sea water.

Answer 1

Hello,

An element is the most basic form of matter, like carbon or sulfur. (Anything on the periodic table)

A compound is a combination of elements, like hydrogen peroxide and propane.

If we can separate substances easily, we have a heterogeneous mixture. If we have to use some sort of device or apply heat to separate a mixture, it is a homogenous mixture. All solutions are a homogenous mixture. A quick eye test can also help- a chocolate chip cookie is a heterogeneous mixture of chocolate chips and cookie batter; you can see the chocolate chips as separate from the cookie. Milk is a homogenous mixture.

Air- homogenous

Sea water- homogenous

Vodka- homogenous

Brass- an alloy of copper and zinc- homogenous

Blood- homogenous
