Answer:
The cell reaction reaches equilibrium quickly and the cell emf becomes zero.
Explanation:
The purpose of a salt bridge is not to move electrons from the electrolyte, its main function is to maintain charge balance because the electrons are moving from one-half cell to the other.
A solution of a salt that dissociates easily is normally used. Water is ineffective at functioning as a salt bridge. Hence the effect stated in the answer.
Answer:
The answer to your question is: C2 = 0.0004 M
Explanation:
Data
pH = 2.5; V = 1.0 L
V2 = 8.0 L C2 = ?
Formula
C1V1 = C2V2
C2 = C1V1 / V2
pH = -log[H⁺]
Process
[H⁺] = antilog -pH
[H⁺] = antilog (-2.5)
[H⁺] = 0.003 M = C1
Finally
(0.003)(1 l) = C2(8)
C2 = 0.003 / 8
C2 = 0.0004 M
Plate tectonics is the theory that Earth's crust is composed of many plates that are moving slowly over time.

What is moles?</h3>
Mole, also spelled mol, in chemistry, a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
The mole designates an extremely large number of units, 6.02214076 × 
. The General Conference on Weights and Measures defined the mole as this number for the International System of Units (SI) effective from May 20, 2019. The mole was previously defined as the number of atoms determined experimentally to be found in 12 grams of carbon-12.
The number of units in a mole also bears the name Avogadro’s number, or Avogadro’s constant, in honour of the Italian physicist Amedeo Avogadro (1776–1856). Avogadro proposed that equal volumes of gases under the same conditions contain the same number of molecules, a hypothesis that proved useful in determining atomic and molecular weights and which led to the concept of the mole.
