Answer:
The correct option is: d. higher ... lower
Explanation:
Osmosis is a spontaneous process that involves the movement of the solvent particles from the region having <u>low solute concentration to the region having high solute concentration</u>, through a semipermeable membrane. It is a spontaneous process.
Osmosis can also be described as the movement of solvent particles from the region with <u>high solvent concentration to low solvent concentration.</u>
C₅H₁₂ + 8O₂ = 5CO₂ + 6H₂O
5CO₂ - 10O
6H₂O - 6O
16O - 8O₂
8 moles of molecular oxygen are consumed
In a reaction involving sodium metal and chlorine gas, the amount of sodium metal required to react with 0.950 grams of chlorine gas would be 0.62 grams
<h3>Stoichiometric calculation</h3>
From the balanced equation of the reaction:
2Na (s) + Cl2 (g) ---------> 2NaCl (s)
The mole ratio of Na to Cl2 is 2:1.
Mole of 0.950 grams of chlorine gas = 0.950/70.906
= 0.0134 moles
Equivalent mole of Na = 0.0134 x 2 = 0.0268 moles
Mass of 0.0268 moles Na = 0.0268 x 22.99
= 0.62 grams

A. A substance changes size or phase.
Answer:
When a light is shone on the extract, pigment molecules absorb energy. Because the pigments have been isolated from the thylakoid membranes of the chloroplasts, the energy cannot be used for photosynthesis. Instead, the energy is released as heat and light in a process called fluorescence.
