each of the following nuclides is used in nuclear medicine. list them in order of most active to least active
Naddika [18.5K]

Different radioactive nuclides decay into their respective daughter nuclides at distinct rates. Some of the nuclides decay briskly, while others decay gradually. The time it consumes for half of the parent nuclide in a radioactive sample to decay to the daughter nuclides is known as the half-life of the radioactive sample.  

The nuclides, which decay briskly exhibit short half-lives and are very active. The half-life can be utilized to find the rates of radioactive decay. In the given question, the half-lives of various nuclides are given. So, the order to the most active (shortest half-life or largest number of decays per second) to least reactive (largest half-life or the smallest number of decays per second) is:  

Tc-99m > Y-90 > In-111 > I-131

The equilibrium constant, Kc, for the reaction N2O4(g)⇌2NO2(g) is 5.0×10−3. If the equilibrium mixture contains [NO2] = 0.050 M
Sergeu [11.5K]

Answer:

0.50 M is the molar concentration of N_2O_4.

Explanation:

The equilibrium constant of the reaction = K_c=5.0\times 10^{-3}

N_2O_4(g)\rightleftharpoons 2NO_2(g)

Equilibrium concentration of NO_2 = 0.050 M

[NO_2]=0.050 M

Equilibrium concentration of N_2O_4 = ?

[N_2O_4]= x

The equilibrium constant of the reaction is given aSL:

K_c=\frac{[NO_2]^2}{[N_2O_4]}

K_c=\frac{(0.050 M)^2}{x}=5.0\times 10^{-3}

x = 0.50 M

0.50 M is the molar concentration of N_2O_4.
