Initial concentration of Br- = 2.25 x 10e-3
M1V1=M2V2
therefore M2= M1V1/V2
=( 2.25x10e-3x14)/(14+25+76)=( 2.25x10e-3x14)/(115)=2.74x10e-4M
This relation is true as the components are unnreactive & NaBr is a salt which undergoes
complete dissociation inn aqueous medium.

A Shareholder of a company is holding a share in the assets of the company. A shareholder is also entitled to the profits which company makes by using those assets. As the basic fomat of company distinguishes the Management function from the ownership, People managing the company may or maynot be the owners i.e share holders of the company. Regulators often require the companies to obtain approval of the shareholders via a resolution in the shareholders meeting, thus the deciding power rests with the shareholders. However the extent of powers are contained in the Legislature governing that corporation. Shareholders have right in the assets of the corporation not in the day to day mangement of the corporation.

(A) The answer is b. increases Electricity in the form of electrons are transported through the solution by charged ions of the electrolyte. As the electrolyte concentration increases, so does the number of charge carriers and hence the amount of charge and electricity conducted increases. (B) Acetic acid (CH3COOH) is a weak acid and partially ionizes in water: CH3COOH + H2O => CH3COO- + H3O+ The charged acetate (CH3COO- ) and hydroxonium (H3O+) ions are responsible for electrical conductivity. In 6 M acetic acid, water is in excess and and the ionization proceeds as shown above to give an electrolyte solution with charged ions that conduct electricity. In glacial acetic acid, there is very little water present and ionization is negliglble. Almost all the acetic acid remains in the non-conducting molecular form (CH3COOH) and there are no charged ions present. Thus glacial acetic acid does not conduct electricity.

Thermodynamic entropy is a non-conserved state function that is of great importance in the sciences of physics and chemistry. Historically, the concept of entropy evolved in order to explain why some processes (permitted by conservation laws) occur spontaneously while their time reversals (also permitted by conservation laws) do not; systems tend to progress in the direction of increasing entropy. For isolated systems, entropy never decreases. This fact has several important consequences in science: first, it prohibits \"perpetual motion\" machines; and second, it implies the arrow of entropy has the same directionality as the arrow of time. Increases in entropy correspond to irreversible changes in a system, because some energy is expended as waste heat, limiting the amount of work a system can do. In statistical mechanics, entropy is a measure of the number of ways in which a system may be arranged, often taken to be a measure of \"disorder\" (the higher the entropy, the higher the disorder). This definition describes the entropy as being proportional to the natural logarithm of the number of possible microscopic configurations of the individual atoms and molecules of the system (microstates) which could give rise to the observed macroscopic state (macrostate) of the system. The constant of proportionality is the Boltzmann constant. - Wiki Solution Thermodynamic entropy is a non-conserved state function that is of great importance in the sciences of physics and chemistry.

A. So before we can come up with the chemical equation, we firsthave to understand the components of the salt we are to dissolve.What does it break into? What are the charges of each component ofthe salt, and their individual chemical formulas? So first we lookat the name \"strontium iodate\" so we know that it breaks intostrontium with some charge in water and iodate. Strontium Iodate --> some Strontium + some Iodate (in water) Now for the second question, what are the charges and the chemicalformula of each part? So for strontium, we know that it is analkaline earth metal (or in group II), so we know that like Ca orMg, Sr is most likely to hold a charge of 2+. So we\'ll say that wehave a Sr2+ in solution. How about iodate? By otherremembering or looking it up we find that it isIO3-. So how would we pair these in a salt? Since we know that Sr has a2+ charge and iodate has a 1- charge, we know that to balance atotal charge of 0, we need 2 iodates per Sr making: Sr(IO3)2 as the salt dissolving in solution.This clearly then breaks into 1 Sr2+ and 2IO3- in water. B. Now that we know the reaction, how do the two speciesconcentrations relate to themselves in solution? Well we alreadyanswered this question. By saying that we need to pair 2 iodatesfor each Sr cation, we know that iodate concentration must bedouble that of the Sr cation in water. Cheers. Solution A.
