Answer: Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods. This uses radioactive minerals that occur in rocks and fossils almost like a geological clock. ... These isotopes break down at a constant rate over time through radioactive decay.
Answer:
nitrogen
Explanation:
as the group number increases, the atomic radius decreases
Avogadro's law states that in a mole of any substance, there are 
atoms. This means that in the given sample, there are
- The atomic mass of sulfur is 32.06 amu.
- The atomic mass of oxygen is 15.9994 amu.
So, the atomic mass of sulfur dioxide is
Therefore, the mass is:
In eukaryotic cells the citric acid cycle takes place in the matrix of the mitochondria.
The answer is 'equal'. Hydroxide ions are OH- and Hydrogen ions are H+. Have you noticed they're opposite charges? Positive + negative = neutral. That's all there is to it :)
