The Henderson-hasselbalch equation for a propanoic acid solution is expressed as [A-]/[HA] = 2.7.
<h3>What is
Henderson H
asselbalch Equation ?</h3>
It is expressed as:
pH = pKa + log([A-]/[HA].
where,
[A-] is molar concentration of conjugate base and
[HA] is molar concentration of weak acid.
Given,
pH = 5.30
Substitute the value in the Henderson Hasselbalch equation
5.30 = 4.874 + log[A-]/ [HA]
log[A-]/[HA] = 5.30 - 4.874
[A-]/[HA] = 10^ 0.426
[A-]/[HA] = 2.7
Thus from the conclusion we can say that The henderson-hasselbalch equation for a propanoic acid solution is expressed as [A-]/[HA] = 2.7.

Answer:
1 km * 1000 m / km * 100 cm / m = 10^5 cm / km
V = 4 / 3 pi R^3
V = 4 / 3 * pi * (7.01 * 10^5 * 10^5)^3 = 4 / 3 pi * 344 * (10^10)^3
V = 1.443^10^3 * 10^30 = 1.44 10^33cm^3
Answer:
BeCl2 + 2AgNO3 ---> Be(NO3)2 + 2AgCl
Answer:
A hydrogen bonding is a bond class that is produced from the attraction existing in a hydrogen atom and an oxygen, fluorine or nitrogen atom with a negative charge. This attraction, meanwhile, is known as dipole-dipole interaction and links the positive pole of one molecule with the negative pole of another.
Explanation:
The hydrogen atom, which has a positive charge, is known as the donor atom, while the oxygen, fluorine, chlorine or nitrogen atom is the bond acceptor atom. In the substance in which they are most effective is in the water.
Hydrogen bonds have only one third of the strength of covalent bonds, but they have important effects on the properties of the substances in which they occur, especially in terms of melting and boiling points in crystal structures.
Metallurgy is the science and technology of metals and alloys. The study of metallurgy can be divided into three general groups: ... Process metallurgy is concerned with the extraction of metals from their ores and the refining of metals.
