For radioactive dating to be possible, the sample must contain a measurable amount of a radioactive isotope with a known decay rate. The sample must be isolated from sources of contamination that could affect the accuracy of the dating. Additionally, the sample must have remained a closed system since the radioactive isotopes were incorporated, in order to accurately measure the decay products.
The sample must contain Uranium-235.
A soil sample is more likely to contain organic compounds compared to a rock sample. Organic compounds are often derived from plant and animal matter, which can decompose in soil, while rocks are typically composed of inorganic minerals.
A sample of air is passed through concentrated sulfuric acid to remove moisture. Sulfuric acid is a strong dehydrating agent that can absorb water vapor from the air, allowing for the collection of a dry sample that is free from moisture.
The sample of water that contains the most heat energy is the 20 g sample at 10 degrees Celsius because it has double the mass of the 10 g sample. Heat energy is directly proportional to mass, so the sample with more mass will contain more heat energy.

Yes, a cat's stool sample can contain traces of litter if the cat ingests it while grooming itself.
Yes, a cat's stool sample can contain litter if the cat ingests some of the litter while using the litter box.
A sample that goes through all the steps of an experiment but does not contain the variable being tested is called a control group. The control group serves as a baseline to compare the effects of the variable in the experimental group, helping to isolate the impact of the variable being tested. This comparison is essential for validating the results of the experiment.
A pure and fresh prepared uranium sample don't contain plutonium; only the irradiated (in a nuclear reactor) uranium contain plutonium.
A 88,1 gram sample of Ag contain 4,9185.10e23 atoms.
350 g sample of CO contain 12,49 moles.
