What is the half life of a compound if 75% of a given sampleof
Contact [7]

Answer:

t_{1/2}=30.14\ min

Explanation:

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

Given:

75 % is decomposed which means that 0.75 of [A_0] is decomposed. So,

\frac {[A_t]}{[A_0]} = 1 - 0.75 = 0.25

t = 60 min

\frac {[A_t]}{[A_0]}=e^{-k\times t}

0.25=e^{-k\times 60}

k = 0.023 min⁻¹

Considering the expression for half life as:-

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

Where, k is rate constant

So,  

t_{1/2}=\frac{\ln 2}{0.023}\ min

t_{1/2}=30.14\ min

Which type of ecological succession has occurred? Could it be both? Why?
maria [59]
Two different types of succession—primary and secondary—have been distinguished. Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier,I hope that’s correct

Do all isotopes decay over time ?
ser-zykov [4K]
Certain naturally occurring radioactive isotopes are unstable: Their nucleus breaks apart, undergoing nuclear decay. ... All elements with 84 or more protons are unstable; they eventually undergo decay. Other isotopes with fewer protons in their nucleus are also radioactive.
