Marble is considered a natural rock that is primarily composed of calcite or dolomite, making it a pure substance in terms of its mineral composition. However, since marble can contain various impurities, such as other minerals or organic materials, it can also be seen as a mixture to some extent. Ultimately, while the main component is a pure mineral, the presence of these impurities means that marble can be classified as a mixture in a broader sense.
What else can I help you with?
Is rock salt a mixture or pure substance Is rock a mixture or a pure substance?
Rock salt contains all the minerals found in the seawater from which it formed. These will be many, but NaCl will be the main one.
Is lime stone a pure substance?
Limestone is not a pure substance. It is a sedimentary rock composed of various minerals such as calcite, aragonite, and dolomite. These minerals can vary in composition and impurities, making limestone a heterogeneous mixture rather than a pure substance.
Is sedimentary rock a element mixture or 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.
Pure limestone when metamorphosed is what?
When pure limestone undergoes metamorphism, it can transform into marble. Marble is a metamorphic rock composed primarily of calcite crystals that have recrystallized under high pressure and temperature conditions.
Is marble an igneous crystalline rock?
Answer: Marble mainly consists of calcium carbonate (CaCO3), so no, it is an inorganic substance.
Is a rock a substance?
A rock is a complex mixture of compounds, not a pure substance.
Is a rock a pure substance or a mixture?
It is a pure substance, because it has other compounds to it.

Rock salt contains all the minerals found in the seawater from which it formed. These will be many, but NaCl will be the main one.
Is marble a heterogeneous or homogeneous mixture or pure substance?
Marble is a homogeneous mixture. It is composed primarily of the mineral calcite, along with other minerals like quartz and mica, all mixed together in a uniform manner. It is not a pure substance since it is made up of multiple components.
Is gravel a pure substance or a mixture?
Geavel is not pure, it is an undescriptable mixture of unknown composition

Is granite a pure substance or a heterogeneous or a homogeneous?
Granite is a rock, a non-homogeneous mixture of minerals.

It is a heterogenous mixture, not a pure substance. Felix Ferrow
Is sedimentary rock a element mixture or compound?

Are rocks and minerals pure substances?
No, sandstone is not a pure substance. Sandstone is a mixture of eroded rock particles (grains of sand) that have been put under pressure over millions of years until they have formed a solid (sandstone) rock layer.Sandstone is a sedimentary rock, mainly of sand-sized mineral particles or rock fragments. Sandstone is mainly composed of quartz or feldspar.
How could a determine whether an unknown substance was a mineral?
A mineral is any chemical compound with a constant chemical composition, which of course is the definition of a "pure substance". In earth science you might be distinguishing between "rock" and "mineral". A mineral is a pure substance. A rock is a mixture of two or more minerals in various proportions. For instance, the rock granite is made up of three minerals: quartz, feldspar and biotite (mica).
