For the equilibrium that
you have written...
<span>H2CO3 + H2O <==> HCO3-
+
H3O+ </span>
<span>acid base conjugate base conjugate acid</span>
We know that carbon dioxide
reacts with water to form "carbonic acid." However what we really
call as carbonic acid is not the weak acid H2CO3; H2CO3 does not even exist in
aqueous solution. What really we call as carbonic acid is simply CO2 dissolved
in water which is in equilibrium with small amounts of H+ and HCO3-. HCO3^- is
the intermediate substance between CO2 and CO3^2-. By adding OH- to HCO3^- we produce
CO3^2-. Adding H+ to HCO3 produces CO2.
CO2(aq) + H2O(l) <==> H+ + HCO3^- ........
carbonic acid .... midrange pH values
HCO3^- + OH- <==> CO3^2- + H2O(l) ....... formation of
carbonate ion .... basic
HCO3^- + H+ <==> CO2(g) + H2O(l) .......... formation
of carbon dioxide .. acidic

Answer:
At high altitude, it takes longer to cook spaghetti. (Ans 2).
Explanation:
A colligative property of a solution depends on the number of ions or solute particles present in the solution, not the type of the solute. Due to pressure change boiling points have nothing to do with colligative property and solutions.
Colligative properties include:
1) Freezing point depression.
2) Vapor pressure lowering.
3) Boiling point elevation.
4) Osmotic pressure.
At high altitude, the air is under less atmospheric pressure than it is at sea level. So at high altitude, it takes longer to cook spaghetti, because of the water it boils in is not as hot as is it at sea level.
True, because his model has the electrons in the sphere of the atom, Thomson’s model was called the “Plum Pudding” model because it was popular and relatable at his time.
Hope this helps!! ^v^
