(3.5mol)(24.106 g/1mol c6h6) =84.371 g C6H6
Each isotope has a unique rate of decay, making them suitable for determining the dates of ancient artifacts. The answer is "rate of decay of the isotope."
Answer:
cation +2
Explanation:
A cation is a positively charged ion, while an anion is a negatively charged ion. Contrary to how it sounds, when an atom loses electrons, it's charge becomes more positive. Since the calcium atom lost 2 electrons, it is a positive (+2) ion.
The mass number is reduced by 4 and the atomic number decreases by 2 (because the atom loses 2 protons and 2 neutrons)
