The half-life of iodine-131 is about 8 days. how much of a 50mg sample will be left in 25 days? write your answer rounded to the nearest tenth.

5.73 mg of the sample will be left in 25 days.

Explanation:

Given that:

Half life = 8 days

Where, k is rate constant

So,  

The rate constant, k = 0.08664 days⁻¹

Time = 25 days

Using integrated rate law for first order kinetics as:

Where,  

is the concentration at time t

is the initial concentration  = 50 mg

So,  

5.73 mg of the sample will be left in 25 days.

alienation, transformation, consumption, and the relativity of truth.

you can choose any one of these, they are all important themes.

these themes reflect the distinct sensibilities of both the modernist and postmodern aesthetic movements. (from google, you should paraphrase)

hope this !

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
