Answer: Filtration

Explanation:

Filtration can be defined as the various mechanical, physical or biological operations that separates a solid from the liquid by adding a membrane in between which only allows the movement of liquid from it.

The precipitate is left on the membrane and the liquid is passed on into the vessels. The left over part is solid called precipitate.

Hence, the correct answer is Filtration.

Iron-59 is a beta emitter with a half-life of 44.5 days. If a sample initially contains 180 mg of iron-59, how much iron-59 is l
Jobisdone [24]

Answer:

2.79 mg iron-59 is left in the sample after 267 days.

Explanation:

Given that:

Half life = 44.5 days

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

Where, k is rate constant

So,  

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

k=\frac {ln\ 2}{44.5}\ days^{-1}

The rate constant, k = 0.0156 days⁻¹

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  = 180 mg

Time = 267 days

So,  

[A_t]=180\ mg\times e^{-0.0156\times 267}

[A_t]=180\times e^{-0.0156\times 267}\ mg

[A_t]=2.79\ mg

<u>2.79 mg iron-59 is left in the sample after 267 days.</u>
