Rock is actually a mixture of compounds.
Pumice is neither an element nor a compound. It is a type of volcanic rock that is made up of various minerals and volcanic glass.
Shale is neither an element nor a compound. Shale is a type of sedimentary rock that is made up of a mixture of minerals, organic matter, and other materials.
Compound
Pb is a compound.
how can a rock be an element?? then what is it chemical symbol? it is a heterogeneous mixture composed of various homogeneous mixtures. http://en.wikipedia.org/wiki/Rock_(geology)#Rock_classification
No, it is sodium chloride which is a compound.
Sedimentary rock is not a pure substance with a fixed chemical composition like an element or a compound. It is a mixture of different minerals, organic matter, and rock fragments that have been compacted and cemented together over time through the process of sedimentation.
Pumice is neither an element nor a compound. It is a type of volcanic rock that is made up of various minerals and volcanic glass.
It's a compound. Only two things are mixed to make it.
Shale is neither an element nor a compound. Shale is a type of sedimentary rock that is made up of a mixture of minerals, organic matter, and other materials.
It is usually a compound- several elements
Feldspar is a mineral compound, not an element. It is a group of rock-forming tectosilicate minerals that make up about 60% of the Earth's crust. It is composed of aluminum, silica, and other elements like potassium, sodium, or calcium.
element. Sulfur dioxide (SO2) is a compound
Rock road ice cream is a compound because elements are single pure elements. The sugar in ice cream itself is made up of C12H22O11. When something is made up of more than one element, it is a compound.
Chemical formula for limestone is CaCO3. It is an inorganic compound.
Compound
