Nuclear energy released in nuclear fission and fusion is much larger than chemical reactions because of the astonishing amounts of energy being released at one moment.
How did the Heisenberg uncertainty principle contribute to the idea that electrons occupy "clouds" or "orbitals"? Because the exact position of the electron is not known,it must be assumed that the electron takes up the entire space in an orbital.
To go from molecules, we first need to convert to moles and then convert to grams.
To convert from molecules to moles, we need to divide by Avogadro's constant.
1.15*10^21 molecules * (1 mole/6.022*10^23 molecules) = 0.0019097 moles
To convert from moles to grams, we need to use the molar mass.
The molar mass of P₂O₅ is (2*30.98)+(5*16.00) = 141.96
You can find the molar mass using the periodic table.
0.0019097 moles * (141.96 grams/1 mole) = 0.2711 grams.
Since we have 3 significant digits in 1.15*10^21, that means our final answer is limited to 3 significant digits.
Your final answer is 0.271 grams.
No, because a natural diamond is a feat of nature and it is amazing how nature made the intricate structure in a diamond. synthetic diamonds are created in laboratory conditions, so it feels less 'amazing' that the diamond was created because each diamond doesn't feel so unique.
However, the molecular structure of both synthetic and natural diamonds are identical, so it is nearly impossible to tell the difference (if you don't know which is which).
Hey there!:
1 mole O2 ----------------- 22.4 L ( at STP )
( moles O2 ) -------------- 2.50 L
moles O2 = 2.50 * 1 / 22.4
moles O2 = 2.50 / 22.4
moles O2 = 1.12*10⁻¹
Answer B
Hope that helps!
