According to the second order formula:
1/[At] = K t + 1/[Ao]
and when we have the K constant =0.0265 & we have t = 180 min & we have the initial concentration of A = 4.25 so by substitution:
1/[At] = 0.0265 X 180min + 1/4.25
1/[At] = 5
∴[At] = 1/5 = 0.2 m
The answer is 264.12
The element is Bh (Bohrium). If the ion has a 1 charge, the charge can either be 1+ or 1-. So the ion has to be an element with the atomic number 107 or 109 (Bh or Mt). Using simple math, subtract the atomic number from the mass number to equal 157.
264 - 107 = 157
Convert grams —> mols and then mols —> atoms
We know that there are 6.02 x 10^23 atoms/mol
And we know that there are about 160 grams of fe2o3 per mol
So (79g fe2o3)/(160 g/mol) = .49 mol fe2o3
Now we use avogadro’s number to do
(.49 mol fe2o3)/(6.02 x 10^23 atoms/mol) = the answer.
I’ll leave the easy math to you.
Here is the answer of the given question
A. The water will freeze. This is because if there's not enough heat, water will freeze. Just like in winter. There's not enough heat to keep the water from melting, so it just freezes. Hope this helps!
