I think the answer will be 60 and the reason why is because
Answer:the force from spinning that moves things away from the center
Explanation: ap chem
Answer:
Substance B, boiling point of 105 °C
Explanation:
Non volatile substances have high boiling points
<span>1. Tap water has a small concentration of H+ & OH- ions as well as water molecules, hence there would be permanent dipole-permanent dipole (p.d.-p.d.) forces of attraction between the water molecules (aka H-bonds) as well as ionic bonds between the H+ & OH- ions.
2. Distilled water does not have H+ & OH- ions, hence only H-bonds exist between the water molecules.
3. There are covalent bonds between the individual sugar molecules.
4. There are ionic bonds between the Na+ & Cl- ions in NaCl.
5. There are p.d.-p.d. forces of attraction between the Na+ ions and the O2- partial ions of the water molecules as well as between the Cl- ions and the H+ partial ions of the water molecules. There are also H-bonds between the individual water molecules and ionic bonds between the Na+ & Cl- ions (although these are in much lower abundance than in unsolvated solid NaCl).
6. There are i.d.-i.d. as well as p.d.-p.d. forces of attraction between the sugar molecules and the water molecules. There are also H-bonds between the individual water molecules and covalent bonds within the sugar molecules.</span>

Answer:
The concentration of high-pressure side is 
Explanation:
From the question we are told that
The thickness of the polyethylene is 
The temperature is 
The flux is 
The concentration on the low-pressure side is 
The initial diffusivity is 
The activation energy for diffusion is 
Generally the diffusivity of the oxygen at 600 K can be mathematically evaluated as
substituting values
Generally the flux is mathematically represented as
Where 
is the concentration of oxygen at the higher side
So
substituting values
