Answer:
7.6 days
Explanation:
Radon is a radioactive element and Radon-222 is it's most stable isotope. The half-life of Radon-222 has been found to be approximately 3.8 days.
Let, the initial amount of the Rn-222 = 1 = A
Final amount = 
= A'
We will use the following relation for calculating time elapsed in the decay
Thus,
We can write is as,
Since the base in both sides are equal, powers can also be equal and thus,
So, t = 7.6 days
The compound ch3ch2-sh is in the organic family know as c. thiols
Molarity is a concentration unit, the number of moles of solute divided by the numbers of liters in a solution. Pertaining to chem
Explanation:
1. N/A
2. The difference in color
3. It is making the solution less concentrated, usually by adding more liquid.
4. You need to find the concentration of the solution before it was diluted. Add more of the solvent to the solute as per needed.
5.
a 1 molar solution cannot be made by adding one mole of solute to 1 L of solvent. • Solutions of a desired molality are usually prepared by placing the appropriate amount of solute
