Is bubble chamber one of your choices? Bubble chamber sounds like a good fit for the question.
T is amount after time t
<span>Ao is initial amount </span>
<span>t is time </span>
<span>HL is half life </span>
<span>log (At) = log [ Ao x (1/2)^(t/HL) ] </span>
<span>log (At) = log Ao + log (1/2)^(t/HL) </span>
<span>log (At) = log Ao + (t/HL) x log (1/2) </span>
<span>( log At - log Ao) / log (1/2) = t / HL </span>
<span>log (At/Ao) / log (1/2) = t / HL </span>
<span>HL = t / [( log (At / Ao)) / log (1/2) ] </span>
<span>HL = 14.4 s / [ ( log (12.5 / 50) / log (1/2) ] </span>
<span>HL = 14.4 s / 2 = 7.2 seconds </span>

Good luck and don't forget to rate or mark Brainliest :)
Answer:
A, B, C
Explanation:
Notice that this reaction involves double arrows, meaning this represents an equilibrium reaction in which we observe a forward reaction (combination of hemoglobin and oxygen) and a reverse reaction (decomposition of the oxyhemoglobin complex).
Upon inhalation of oxygen, it accesses the blood of a person and binds to hemoglobin, so the following reaction proceeds to the right.
Similarly, the opposite process takes place in muscles, oxyhemoglobin is decomposed back into hemoglobin and oxygen.
The equilibrium constant reaction is relatively high, since at standard conditions, this is a spontaneous reaction, hemoglobin combines with oxygen without any additional external source of energy.
Azeotrope is a mixture of two or more liquids whose proportions cannot be changed by simple distillation.
Explanation:
Nitic acid and water is an example of azeotrope. The composition of 68% of nitric acid and 32% of water by mass in a boiling point of 393.5k.
The composition of perchloric acid (71.6%) and water boils at 203°c. Pure iron solution weights about 10g is placed in a beaker, hydrochloric acid and nitric acid mixtures are added and heated to dissolve. Add perchloric acid until it evaporate and produces white smoke.cool it down add water and dissolve the salt.
