Answer:
R is universal gas constant
It is has fixed value which would depend upon the units in which P,V and T expressed in the equation PV=nRT
R=
nT
PV
Answer:
NH3(g) + H2O(1) → NH4+(aq) + OH (aq)
HF(aq) + H2O(1) → H3O+(aq) + F (aq)
Explanation:
Acid-base reactions are chemical reactions involving acids and bases. Acids tend to ionize/dissociate in water, a property which determines their strength. Ionization of an acid refers to the acid losing its hydrogen ion (H+) in water solution. An acid ionizes or dissociates to form a conjugate base.
A strong acid is so because it ionizes completely in water i.e. loses all its hydrogen ion (H+) while a weak acid partially ionizes in water.
In the chemical reactions;
1) NH3(g) + H2O(1) → NH4+(aq) + OH (aq)
H20 loses its hydrogen ion (H+) in this reaction to form an anion (OH-). Hence, water (H20) is an acid in this case which ionizes to form a conjugate base (OH-). This is an example of ionization of acid.
2) HF(aq) + H2O(1) → H3O+(aq) + F (aq)
Hydrogen fluoride (HF) loses its hydrogen ion (H+) in the presence of water to form anion (F-). The HF is the acid while F- is it's conjugate base. Thus, an example of ionization of acid

Explanation:
Volcanoes and earthquakes occur due to movement of the Earth's tectonic plates.
<h3>How volcanoes and earthquake occur?</h3>
Both volcanoes and earthquakes occur due to movement of the Earth's tectonic plates. They both occurs due to the heat and energy that is releasing from the Earth's core. Earthquakes can increase or fastens the volcanic eruptions through severe movement of tectonic plates.
Volcanoes eruption occurs when molten rock called magma rises to the surface. Magma is formed when the earth's mantle part melts due to higher temperature.
So we can conclude that volcanoes and earthquakes occur due to movement of the Earth's tectonic plates.
