Explanation:
<u>Answer:</u> The concentration of cow's milk after 5 years is 10691 Bq/L
<u>Explanation:</u>
All the radioactive reactions follow first order kinetics.
The equation used to calculate rate constant from given half life for first order kinetics:
We are given:
Putting values in above equation, we get:
The equation used to calculate time period follows:
where,
= initial concentration of Cow's milk = 12000 Bq/L
N = Concentration of cow's milk after 5 years = ?
t = time = 5 years
k = rate constant =
Putting values in above equation, we get:
Hence, the concentration of cow's milk after 5 years is 10691 Bq/L

Explanation:
Metal that won't be oxidized:
Metal that will not be able to oxidize by any of the other metals is gold.
What causes oxidation to happen?
This chemical reaction might take place in the air or after the metal has been in contact with acids or water. The most prevalent example is corrosion of steel, which occurs when the iron molecules on the surface of steel change into iron oxides, most frequently Fe2O3 and Fe3O4.
If you've ever seen a rusted-out vehicle or corroded metal bits, you've witnessed oxidation in action.
Metals that don't oxidize:
In their native condition, noble metals like platinum or gold resist oxidation. Ruthenium, rhodium, palladium, silver, osmium, and iridium are more examples of these metals. Humans have developed a wide variety of corrosion-resistant alloys, including brass and stainless steel.
