Step-by-step explanation

Firstly, we need to define the terms " element, mixture, and compound"

Element: Element can be defined as a substance that cannot be split into two simpler units by an ordinary chemical reaction.

Mixture: A mixture can be defined as the combination of two or more constituents that are physically combined together.

Compound: Compound can be defined as the combination of two or more elements that are chemically combined together.

The next step is to classify the following into elements, compounds, and mixtures

• Aluminum foil has a formula of Al. This implies that aluminum foil is ,an element

• Brass: Brass is an alloy of copper and zinc. An alloy is considered a homogenous mixture because it is a mixture of two or more metallic elements. Hence, ,brass is a mixture.

• Mik is a, mixture

• Hydrogen sulfide: Hydrogen sulfide consist of two elements namely; hydrogen and sulfur that are chemically combined together. Therefore, ,hydrogen sulfide is a compound.

• Blood is a mixture. Blood is made up of many different particles that can be combined and separated physically..

• Granite is a homogenous mixture because it contains minerals that are clearly distinguishable. Hence, granite is a, mixture

• Baking powder is a ,compound., The chemical formula is ,NaHCO3
