Answer:
The best answer is "E"
NaCl leaves the ascending limb of the loop of Henle through active transport.
Explanation:
The loop of Henle is a U-shaped portion of the tubule that conducts urine within each nephron. It's principal function is the recovery of water and sodium chloride from the urine.
The ascending limb is impermeable to water. NaCl is pumped from the tubule into the interstitium in the ascending limb by active transport. This active transport enables the kidney to establish an osmotic gradient which enables the permeability of water and urea thereby allowing the kidneys to concentrate the urine.
Methane (CH4) forms the molecular solid.
<u>Explanation:</u>
- The molecules which are held together by intermolecular forces are called molecular solids. It is maintained by solids rather than bonds. The force which holds these solids are weaker than other solids.
- It consists of discrete molecules and the cohesive force which binds them together is Vanderwall's force, dipole-dipole interaction and hydrogen bonding. They are held together by an ionic bond or covalent bond.
- The weak intermolecular forces have relatively low melting points which are less than 300 degrees Celsius.
- Organic solvents dissolves Molecular solvents. Many of the molecular solids are soft electrical insulators with low density.
Mass equals density times volume
Because D=m/v
Multiply by v
Dv=m
Answer:
Matter is something that takes up space and has volume?
Hope it helps! Tell me if wrong too. :)
Explanation:
Recall the ideal gas law,
<em>P V</em> = <em>n R T</em>
Find the amount of CO₂ in the sample, <em>n</em> :
<em>P</em> = 686 mm Hg ≈ 91,459 Pa
<em>V</em> = 6.34 L
<em>R</em> = 8.3145 J/(mol•°K)
<em>T</em> = 73 °C = 346.2 °K
→ <em>n</em> = <em>P V</em> / (<em>R</em> <em>T</em> ) ≈ 0.20147 mol
Now find the volume <em>V</em> of the sample when the temperature <em>T</em> is 35 °C = 308.2 °K :
<em>V</em> = <em>n R T</em> / <em>P</em> ≈ 5.6349 L ≈ 5.63 L
