There is none.
Pumice is a mixture.
The chemical composition remain unchanged.
i think is chemical composition its not chemical composition, it's how they were formed
The chemical composition of water remain unchanged.
A chemical change involve a change of composition.
A liquid is a compound or a mixture; the chemical composition is representative for this liquid.
Pumice forms when frothy lava cools rapidly, trapping gas bubbles within the rock. This gives pumice its characteristic streaks or veins, which are typically lighter or darker in color than the rest of the rock. The streaks in pumice can vary depending on the mineral and chemical composition of the magma from which it formed.
quartz, plagioclase and alkali feldspars
None of the above. These terms are used to describe sedimentary rocks. Pumice is igneous.
Pumice can vary in color from white to gray to black. Much of it has to do with the chemical composition. Felsic varieties are most commonly light in color. Mafic varieties can be darker in color.
The chemical composition remain unchanged.
Pumice is typically neutral in pH, meaning it is neither acidic nor basic. This is due to its composition, which is mostly made up of silica and other mineral oxides.
The metamorphic form of pumice is known as "pumiceite." This form of metamorphic rock is created through intense heat and pressure acting on pumice, which causes it to recrystallize and change its mineral composition. Pumiceite typically has a more compact and dense structure compared to pumice.
Pumice is a type of extrusive volcanic rock, produced when lava with a very high content of water and gases (together these are called volatiles) is extruded (or thrown out of) a volcano. Pumice is not a mineral because it does not have a definite composition and lacks a crystalline structure.
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
Yes, the composition of the rocks is as a result of the distinct chemical composition.
