he standard cell potential (E° cell) for the voltaic cell based on the reaction below is ________ V. Sn 2+ (aq) + 2Fe 3+ (aq) →
Cloud [144]

The options in the question are:

a) +0.46 V

b) +0.617 V

c) +1.39 V

d) -0.46 V

e) +1.21 V

Answer:

b) +0.617 V

Explanation:

The equation shows that the anode is Sn2+/Sn4+ while the cathode is Fe3+/Fe2+.

The E° cell is obtained from E°cathode - E°Anode

E°cathode= 0.154V

E°Anode= 0.771V

E° cell= E°cathode - E°Anode= 0.771-0.154=0.617

In the early 1960s, radioactive strontium-90 was released during atmospheric testing of nuclear weapons and got into the bones o
Advocard [28]

Answer:

52.54 %

Explanation:

Half life = 29 years

t_{1/2}=\frac {ln\ 2}{k}

Where, k is rate constant

So,  

k=\frac {ln\ 2}{t_{1/2}}

k=\frac {ln\ 2}{29.0}\ {years}^{-1}

The rate constant, k = 0.023902 hour⁻¹

From 1964 to 1991:

Time = 27 years

Using integrated rate law for first order kinetics as:

[A_t]=[A_0]e^{-kt}

Where,  

[A_t] is the concentration at time t

[A_0] is the initial concentration

So,  

\frac {[A_t]}{[A_0]}=e^{-0.023902\times 27}

\frac {[A_t]}{[A_0]}=0.5245

<u>The strontium-90 remains in the bone = 52.54 %</u>
