Granite and basalt are not pure substances because they are composed of multiple minerals and varying chemical compositions. Granite typically contains quartz, feldspar, and mica, while basalt is primarily made up of plagioclase, pyroxene, and olivine. The presence of these different minerals indicates that they are mixtures rather than single, homogeneous substances. Additionally, their physical and chemical properties can vary depending on the proportions of these constituent minerals.
What else can I help you with?
How could you tell a pure substance from a solution if you didnt know what was in it?
The purity is determined by chemical analysis.
How do you tell pure and mixture apart?
A pure substance consists of only one type of atom or molecule, while a mixture is a combination of two or more different substances. One way to distinguish between them is through physical properties such as boiling point or solubility, as pure substances have consistent properties throughout, while mixtures can vary. Additionally, chemical tests can help determine if a substance is pure or a mixture.
How could you tell if a volcano makes felsite or basalt lava?
Thin lava
How can you tell that sandstone is older than a basalt layer?
If the sandstone is below the basalt layer, it is older. Though caution is advised, to make sure it is really a basalt layer and not an intrusion of gabbro. Other indicators that the sandstone is older is evidence of alteration to the sandstone where the two meet (called a "baked contact") and pieces of sandstone being found in the the basalt.
How can you tell that the sandstone was not deposited on top of basalt layers?
The sandstone layer is older than the basalt. The older rock cannot be on top of the younger rock. The sandstone and the basalt (or basalt dike) are both deposited at the same depth.
What are two reasons why density is a useful property identifying substances?
Density can tell you how "pure" a substance is. Since each substance has a specific density in its "pure" state, having no other substances in its composition, by measuring it density you can tell how pure the mineral or substance is, 99.9% pure gold.
How can you tell if a substance is pure or not?
You can tell if a substance is pure by using techniques like melting point determination or chromatography to compare against known pure samples. If the substance has a consistent melting point or chromatogram, it is likely pure. Impurities can cause a substance to have a lower melting point or show additional peaks in chromatography.
What are two reasons why density is a useful property for identifying substances?
Density is specific for each substance. Also the measurement is generally simple.
What does a chemical formula tell you about a pure substance?
It tells you the elements and the proportions of those elements that are present to make the pure substance.
How could you prove to someone that a clear material is a solution not compound?
well Tell the person its a pure substance so a pure substance can only compound one matter
How could you tell a pure substance from a solution if you didnt know what was in it?
The purity is determined by chemical analysis.
Can you tell if a liquid is a pure substance or a solution by looking at it?
No. On the visible and even the microscopic level a solution is indistinguishable from a pure substance.
How can you tell a pure substance from a mature by its boiling point?
take water for example, if water boils at 100 degrees Celsius then it is pure. if the boiling temperature turns out to be higher or lower (most of the time it is higher) then a substance is impure. salt water boils at 102.8 degrees Celsius.
How do you tell pure and mixture apart?
A pure substance consists of only one type of atom or molecule, while a mixture is a combination of two or more different substances. One way to distinguish between them is through physical properties such as boiling point or solubility, as pure substances have consistent properties throughout, while mixtures can vary. Additionally, chemical tests can help determine if a substance is pure or a mixture.
How could you tell if a volcano makes felsite or basalt lava?

Which feldspar mineral is is granite?
tell ur teacher shes dumb
How can you tell which Basalt rocks has been in the river the longest?
when the rock is more rounded than the others
