Ocean tides are caused by mostly wind but can also be caused by earthquakes
Moles of NH3 = mass of NH3/molecular mass of NH3 = 1.7/17= O.1 MOLES.
Given :
Chlorine's 3p sub level has 5 electrons in it.
To Find :
How many electron(s) more in the 3p sub-level to make it stable.
Solution :
Electronic configuration of Chlorine is :
[Ne] 3s² 3p⁵.
We know, p-orbit is stable with 6 electronic.
Therefore, to stable p-orbit 1 more electron is required in 3p sub-level.
Hence, this is the required solution.
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.
