The higher the energy density of a fuel, the greater the amount of energy it has stored.
<h3>What is the energy density?</h3>
The energy density of a fuel is defined as the amount of energy it possesses per unit volume or per unit weight.
<h3>Characteristics of the energy density</h3>
- It is the amount of energy accumulated in an energy vector per unit volume or mass.
- In general, higher density energy sources and carriers are preferable, as many end uses require concentration of such energy.
- The packaging of energy in liquid hydrocarbons is the one with the highest energy density, that is, the highest energy per volume unit, hence its high use in the transportation sector.
Therefore, we can conclude that in general, fuels, especially low molecular weight fuels, have high energy densities.

Answer:
Neutralization reaction is a reaction between an acid and a base. In general, when the reaction is performed in aqueous media, produce water and salt.
Explanation:
Arrhenius defined a base as a substance who forms OH- ions. Bronsted, define it as an proton acceptor.
On the other hand Arrhenius defined an acid as a substance who form H+ ions. Breonsted define it as proton donor.
Acid + base ----> salt + water
A salt is an ionic compund formed by a cation and anion. All salts are strong electrolytes. An example of a neutralization reaction is:
HCl (ac) + NaOH (ac) -------> NaCl (ac) + H2O(l)
Nevertheless, because the acid and the base are strong electrolytes, in water they are completely dissolved actually look like this:
H+ (ac) + Cl(ac) + Na+(ac) + OH-(ac) ------> Na+(ac) + Cl-(ac) + H2O(l)
Answer:
C. II, III, IV, and V.
Explanation:
Acid buffer is generally formed by the combination of a weak acid as well as the salt of the conjugate base.
Basic buffer is formed the combination of a weak base and also the salt of the conjugate acid.
On dilution the ration of the concentration terms of the salt and weak acid/base does not change. Hence the pH of the buffer solution does not change.
When acid or base is added to buffer, it resists changes in the pH.
Therefore, option (C) is correct.
Do this has extra pictures/examples so I can help?
