The answer is (4) amino acid. This molecule has one carboxyl and one amidogen linked at the same carbon atom. This is the property of amino acid. So this is an amino acid.
Hbro dissociate as follows
HBro---> H+ + BrO-
Ka= (H+)(BrO-) / HBro
PH = -log (H+)
therefore (H+) = 10^-4.48= 3.31 x10^-5
ka is therefore= ( 3.31 x 10^-5)^2/0.55=1.99 x10^-9
After 2 half-lives there will be 25% (1/4th) of the original isotope, and 75% (3/4 th) of the decay product
<h3>What is Half life period ?</h3>
A half life is a measurement of the slope of an exponential decay function.
It is also defined as, the time it takes to halve the concentration of something in a process.
Each half life you will have half of what you had at the beginning of a given half life.

Answer: You meant in constant temperature?
Because temperature is not mentioned at the beginning.
I suppose temperature remains constant, otherwise
there is no enough data for solving the problem
Explanation: According Boyle´s law in constant temperature
pV = constant. So p1V1 = p2V2 and pressure p2 = p1V1 /V2
= 88 atm · 18 l / 12 l = 132 atm.
The independent variable as we can see from the experiment that have been described in this case is the brand of fertilizer that was used in the study.
<h3>What is an experiment?</h3>
When we talk about an experiment, we are talking about the way by which the relation ship between the dependent and the independent variable could be studied. In the experiment, there is a dependent variable which would change values when the variable that is under study in the particular experiment changes value. We have to know that in the realm if science, it is only by the means of experiments that we can be able to establish cause and effect relationships.
In this case, we can see that the experiment that the students were working on has to do with trying to actually find out if brand X fertilizer will affect the growth of Lily plants. This means that they were studying the effect of a fertilizer brand on the growth of the crops.
