Specific activity is the activity per unit mass of a radionuclide and is a physical property of that radionuclide. Activity is a quantity (for which the SI unit is the becquerel) related to radioactivity, and is defined as the number of radioactive transformations per second that occur in a particular radionuclide.
<h3>How do you find the specific activity of an isotopes?</h3>
- Activity = λN.
- = (0.693/8 days) x (1/86,400 sec/day) x (3 x 1017 atoms)
- = 3 x 1011 atoms/sec I-131.
- = 3 x 1011 dps I-131.
<h3>What is the specific activity of Co 60?</h3>
The average specific activity of 60Co in continental aquatic sediments is in the region of 1 Bq. kg-1 dry weight (Eyrolle et al., 2008). Cobalt distribution in the abiotic compartments of continental aquatic systems is characterised by the strong affinity of the element for sediment.

Xenon will react with chlorine to form xcl4
As is shown in the formula :
Cl--Cl--Cl--Cl

X
Answer:
both melting point and boiling points are lower
this is because it becomes easier to break those bonds (they’re actually intermolecular forces) between the atoms sinc they’re weak, and thus require less energy to break.
sorry about the late response...
<u>If an earthworm is exposed to dry conditions, then it will retreat to a moist place because its skin needs to stay moist for the earthworm to survive.</u>
