Answer:
The absolute zero temperature T = - 269.91° C
Explanation:
From the given information:
The plot of the volume of the experimental data against the celsius temperature can be expressed mathematically as:
V = mT + c
V = 0.0741 × T+c --- (1)
where;
m, which is the straight line of the slope = 0.0741
replacing the value of V to be = 20 L, T= 0.
Then:
20 = 0.0741 × 0 + c
20 = c
From equation (1), replacing the value of c with 20, we have:
V = 0.0741 × T+20
SO, to determine absolute zero temperature: we have the volume to be zero at absolute zero temperature, Thus:
0 = 0.0741 × T+20
0.0741 T + 20 = 0
0.0741 T = - 20

T = - 269.91° C
Bro2 is polar because the rules for overall polarity of Neutral Species Arrangement of Group Linear Trigonal Planar Tetrahedral Trigonal Bipyramidal Octahedral Polarity if atoms on either side of the center atom are different, the species is polar if any group around the central atom is different.
The pH of a solution is calculated as pH = -log[H+], where [H+] is the concentration of H+ ions. Based on the given concentration in the problem,
pH = -log(1.87 x 10^-13 M) = 12.73
Therefore, the pH of the solution is 12.73, and this implies a strongly basic solution.
<span> Scientific reasoning consists of observation, forming a workable hypothesis and arriving at a conclusion. Almost without exception major scientific discoveries were made and are being made today based on these same precepts. It only seems logical when an individual makes a difficult decision he/she will apply all or part of these processes. Let;s say that you want to make someone;s acquaintance to possibly become serious. Certainly, you would begin by quietly observing them, then you might make a hypothesis, "This person might make a good companion for me." Then in your conclusion you would test your hypothesis and proceed as directed. THis may be a bit simplistic, and I hope that it helps.</span>
