Answer:
40 mL
Explanation:
V2=P1V1/P2
You can check this by knowing that P and V at constant T have an inverse relationship. Hence, this is correct.
The mass number is equal to the number of protons plus the number of neutrons. From the periodic table, we can see that chromium has an atomic number of 24, which means its nucleus contains 24 protons. ... Therefore, the chromium-52 isotope contains 28 neutrons in its nucleus.
Answer:
sound is given off
Explanation:
due to a number of scientific research sound that is given off of an object is not due to a chemical reaction.
For a radioactive isotope has an activity of 9.60 mCi. , the half-life of the isotope is mathematically given as
t0.5 = 23893 s
<h3>What is the half-life of the isotope?</h3>
Generally, the equation for the half-life is mathematically given as
t0.5=T*0.693
Where
A = A0 e^(-t/T)
t/T = lnA0/A
3.75 hours/T=ln 9.60/7.39
T = 34478.5 s
Therefore
t1/2 = TX0.693
t0.5 = 23893 s
In conclusion, the half life
t0.5 = 23893 s
