Answer:I believe your answer would be option B) dilute. Hope this helps.
Explanation:
Answer:
Kinetic energy is the energy that an object has because of its motion. The molecules in a substance have a range of kinetic energies because they don't all move at the same speed. As a substance absorbs heat the particles move faster so the average kinetic energy and therefore the temperature increases.
Answer:
True.
Explanation:
This process is known as chemiosmosis in which there is a movement of ions across semipermeable membrane. Hydrogen ions moves from region of its higher concentration to the region of lower concentration. As this process belongs to the diffusion or osmosis of water molecules across cell membrane that is why known as chemiosmosis.
ATP synthase is an enzyme which function is to form ATP by using free energy generated in result of movement of hydrogen ions.
Answer:
D. length × width
Explanation:
eg. 30 cm(length) × 20cm(width) = 600cm²
Answer
Naphthalene is a non electrolyte
If the unknown compound is an electrolyte it gives 2 or more ions in solution
( NaCl >> Na+ + Cl- => 2 ions
Ca(NO3)2 >> Ca2+ + 2 NO3- => 3 ions)
the f.p. lowering is directly proportional to the molal concentration of dissolved ions in the solution )
For naphthalene
delta T = 1.86 x m
for a salt that gives 2 ions
delta T = 1.86 x m x 2
hence the lowering in freezion point of unkown is greater then napthalene
