<span>In a dissolving process,
energy is required to overcome the forces of attraction between the solvent
particles. The first step is for the solvent particles to move in order for
solute particles to enter the system. This process is endothermic where energy
flows into the system. The second step is when solute particles must separate
from other solute particles. Lastly, the solute should move between solvent
particles.</span>
Answer:
True
Explanation:
Carbon dioxide is transported by the blood in the dissolved form. carbonic anhydrase is the enzyme which is a metalloenzyme having zinc at active site converts carbon dioxide into carbonic acid which dissolves in the blood.
Thus,
H₂O (l) + CO₂ (g) ⇔ H⁺(aq) + HCO₃²⁻(aq)
The kidneys in the body help to control the acid base balance. The hydrogen ion secretion in the body leads to the generation and reabsorption of the bicarbonate ions to form carbon dioxide in order to nullify the effect of the acid generated and thus the pH of the blood is maintained.
You would use the formula:
n =
Where m is the mass, and M is molar mass (the periodic table would be used for this)
In this case, we need to rearrange the formula to find m
m = nM
= 5.40 x 6.941
= 37.5g
Hope this helped! Ask me if there's any part of the working you don't understand :)
Oh man. Silver coating to dampen radiating heat is great but that, of course does not tell you the temperature of the fluid inside; I would definitely add a small thermostat somewhere around the exterior. that's the only improvement I would suggest, as a standard for all.
