Answer:
Explanation:
The molecular mass of C2H6 is approximately 30 or [(2 x 12) + (6 x 1)]. Therefore the molecule is about 2.5 times as heavy as the 12C atom or about the same mass as the NO atom with a molecular mass of 30 or (14+16).
Answer:
Procedure (2)
Explanation:
Assume the dialyses come to equilibrium in the allotted times.
Procedure (1)
If you are dialyzing 5 mL of sample against 4 L of water, the concentration of NaCl will be decreased by a factor of
Procedure (2)
For the first dialysis, the factor is
After a second dialysis, the original concentration of NaCl will be reduced by a factor of
Procedure (2) is more efficient by a factor of
Answer:
Five Types of Introductions.
“Inquisitive” Explain why your subject is important, curious, or interesting.
“Paradoxical” Explain what aspects of your subject seem improbable. ...
“Corrective” Explain how your subject has been misunderstood or misrepresented by others. ...
B. Polar Covalent, NO is not a symmetrical molecule, therefore making it Polar rather than Non-Polar.
1 mole ------------ 6.02x10²³ atoms
5.88 moles ---- ?
atoms = 5.88 * 6.02x10²³ / 1
= 3.539x10²⁴ atoms
hope this helps!
