What else can I help you with?
Is a sample composed of atoms only having the same atomic number an isomer?
No. (Element is the word you're looking for.)
How phleger core operate?
The Pheiffer core is an analytical technique used in geology to extract a continuous cylinder of rock or sediment sample from the subsurface. It involves drilling a hollow tube into the Earth and retrieving a cylindrical section of material. This core sample can then be analyzed to understand the composition, structure, and history of the rocks or sediments.
Why is a sample of matter considered a pure substance?
A pure substance is either an element or compound. Elements are composed of only one kind of atom, and compounds are composed of a definite proportion of atoms of different elements that is always the same.
Is yellowish clear and odorless water an example of pure water?
no, pure water is absolutely clear. it doesnt have any color whatsoever. if there is a yellowish color, it means there are impurities in the sample.
Why may a geologist have to break a mineral sample to determine its true color?
Rocks are exposed to the elements and undergo weathering. This can cause the minerals that they are composed of and that are exposed at the surface to become discoloured which can make them hard to identify. A geologist will often use a geological hammer to crack the rock sample to see the fresh, unweathered minerals.
How is a sample oxygen different from a sample of a water?
A sample of oxygen is a pure gas composed of oxygen molecules (O2), while a sample of water is a liquid composed of hydrogen and oxygen atoms (H2O). These substances have different physical properties and chemical compositions, with oxygen being a gas and water being a liquid at room temperature.
A sample is composed completely of gold absolutely free of impurities Which term or terms could be used to describe this sample?
The sample could be described as pure gold or 100% pure gold.
How many half-lives would be necessary for a sample of parent isotopes to decay to the point that only one-half of the sample is composed of parent isotopes?
It would take one half-life for a sample of parent isotopes to decay to the point where only one-half of the sample is composed of parent isotopes. Each half-life reduces the amount of parent isotopes by half.
How many half-lives would be necessary for a sample of parent isotopes to decay to the point that only one-half of the sample is composed of parent isotope?
One half life.
Is leaves a sample of matter?
Yes, leaves are a sample of matter. Matter is anything that has mass and takes up space. Leaves are composed of atoms and molecules, making them a form of matter.
Is a sample composed of atoms only having the same atomic number an isomer?
No. (Element is the word you're looking for.)
What three elements are likely to be found in a sample of soil and rocks?
soil- Clayey soil, sandy soil, and loamy soil rock-metamorphic rock, instrusive/extrusive rock, sediments
Sample of steel is composed of 5 percent carbon and 95 percent iron Which is the solvent?
The steel (solute) is being dissolved into the iron (solvent)
What color is the lithosphere?
The lithosphere does not have a specific color as it is a rigid outer layer of Earth that includes the crust and part of the upper mantle. These layers are composed of various minerals and rocks which can vary in color depending on their composition.

The Pheiffer core is an analytical technique used in geology to extract a continuous cylinder of rock or sediment sample from the subsurface. It involves drilling a hollow tube into the Earth and retrieving a cylindrical section of material. This core sample can then be analyzed to understand the composition, structure, and history of the rocks or sediments.
How many types of molecules with different masses exist in a sample of chlorine gas if the same exists entirely as diatomic molecules?
In a sample of chlorine gas, all molecules are diatomic composed of two chlorine atoms. This means there is only one type of molecule in the sample, with a molecular formula Cl2.
Why is a sample of matter considered a pure substance?
A pure substance is either an element or compound. Elements are composed of only one kind of atom, and compounds are composed of a definite proportion of atoms of different elements that is always the same.
