Ability to move up through thin tunes because a physical property is something you can observe about the matter. Out of all of them this one does not fit.
Becuse the earth rotates the opisate way on the other side of the equator forgive me if im wrong.
Answer is: empirical formula of the product is Br₂O₅.
Chemical reaction: x/2Br₂ + y/3O₃ → BrₓOy.
m(Br₂) = 1,250 g.
m(BrₓOy) = 1,876 g.
n(Br₂) = m(Br₂) ÷ M(Br₂).
n(Br₂) = 1,25 g ÷ 159,81 g/mol.
n(Br₂) = 0,0078 mol.
n(Br) = 2 · 0,0078 mol = 0,0156 mol.
m(O₃) = 1,876 g - 1,25 g = 0,626 g.
n(O₃) = 0,626 g ÷ 48 g/mol = 0,013 mol.
n(O) = 0,039 · 3 = 0,039 mol
n(Br) : n(O) = 0,0156 mol : 0,039 mol.
n(Br) : n(O) = 1 : 2,5.
<u>Answer:</u> The molar concentration of ammonia is 3.008 M
<u>Explanation:</u>
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is 
We are given:
Putting values in above equation, we get:
Hence, the molar concentration of ammonia is 3.008 M
This is pseudoscience, because:
1) <span>The researchers were so excited to report that they had discovered a fuel that burns so hot that it becomes cold. - This would have to be proven again. It may not be this that caused the explosion.
2) </span><span>Much to the relief of the original team or researchers, no other scientist could ever replicate their find. - It can't be replicated, so once again, it proves that it may not be that the fuel burns so hot it becomes cold
3)</span><span>The researchers quickly wrote up a report, created a press release, and applied for a patent. - The report can have errors if it had been 'quickly' written. Also, because it could not be replicated, there is no need for a patent, as it could not be 'proven' again
hope this helps</span>
