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
The correct answer is c
No because the amount of light absorbed
Answer:
2.91 grams of Magnesium
Explanation:
I put a picture . I used the molar mass of magnesium which can be calculated from the periodic table or simply google it. :) I hope it helps - Enrique
The balanced equation is attached in the image below. The coefficients are 2, 2, blank.
Answer: 1.91 moles
Explanation:
First you want to find the molar mass of NaCL
Na = 22.99g Cl = 35.45g
22.99g + 35.45g = 54.44g
Then divide 111.5g by 54.44g and this will give you moles.
