Answer: A 13.88 mL of the concentrated acid would be required to make 250. mL of a 1.00 M 
solution.
Explanation:
Given: 
= 18.0 M, 
= ?
= 1.00 M, 
= 250 mL
Formula used to calculate the volume of concentrated acid is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that 13.88 mL of the concentrated acid would be required to make 250. mL of a 1.00 M solution.
Atoms of elements below atomic number 20 do not split because of stable nucleus.
Stability of nucleus is determined by neutron/proton ratio.
For light stable nuclides, number of protons ans neutrons are same. For heavy nuclides, number of neutrons is more than the number of protons.
Here the type of decay is alpha decay because number of nucleons(protons and neutrons) changes.
Hence option d is correct.
no, u will have to soak then in order for them to die

Answer:
1.4e+8 bismuth atoms
Explanation:
If 10³ mm = 10¹² pm
then 44 mm = X pm
X = (44 × 10¹²) / 10³ = 44 × 10⁹ pm (which is the cookie diameter in picometers)
Now we can calculate the number of bismuth atoms needed to span the diameter of the cookie:
number of bismuth atoms = cookie diameter / bismuth atom diameter
number of bismuth atoms = 44 × 10⁹ / 320 = 0.1375 × 10⁹ atoms = 1.375 × 10⁸ atoms
And now to respect the answer format requested by the problem:
1.375 × 10⁸ = 1.375e+8 ≈ 1.4e+8
