Answer:
1 Å = 1.0 × 10⁻¹ nm
1 Å = 1.0 × 10² pm
Explanation:
Angstrom is the unit of the length which is equal to one ten-billionth of the metre or 10⁻¹⁰ m. It is represented by the symbol is Å .
Angstrom is not part of SI system of the units, but it is considered as a part of metric system.
Angstrom is used often in natural sciences as well as technology in order to express the sizes of atoms / molecules, and the lengths of the chemical bonds, etc.
1 Å = 10⁻¹⁰ m
1 nm = 10⁻⁹ m
1 pm = 10⁻¹² m
So,
1 Å = 1.0 × 10⁻¹ nm
1 Å = 1.0 × 10² pm
Answer:
The pH of the resulting solution is 9.02.
Explanation:
The initial pH of the buffer solution can be found using the Henderson-Hasselbalch equation:

Now, the perchloric acid added will react with ammonia:

Also, the moles of ammonium chloride will increase in the same quantity according to the following reaction:
NH₃ + H₃O⁺ ⇄ NH₄⁺ + H₂O

Finally, we can calculate the pH of the resulting solution:

Therefore, the pH of the resulting solution is 9.02.
I hope it helps you!
Answer:
its either C or D my guess is C though because 35.0g of hyddrogen is =1.03 mol
