Increases pressure (inverse relationship) because as you decrease temperature, molecules are moving slower and have less kinetic energy. Pressure decreases as you increase temperature because molecules move past each other quicker, so they don’t bump into each other with as much force.
Answer:
13.687 grams of salt should be added
The total grams of 8.6% of brine solution produced is 852.687g
Explanation:
Solution mass= 962g
Salt= 6.2%
Water = 93.8%
962 gram of water is made up of:
902.356g ( due to vaporization which reduces mass)
= 902.356 - 123
= 779. 356g of water
59.644g of salt.
If we add x gram of salt for making brine solution up to 8.6%
=(59. 644g + x)g.of salt
% salt = Mass of Salt / Total mass of solution
= 0.086= 59.644 + x / 779.356 + 59.644 + x
= 59.644 + x / 839 + x
x= 13.687 g of salt
Grams of 8.6% brine solution will be:
Gram of water + total gram of salt added to form 8.6% brine solution.
= 779.356g +59.644g + 13.687g
= 852.687g
The total grams of 8.6% of brine solution produced is 852.687g
Answer:
percent composition for CO2 is 0.04%
Based on the fgiven K_{a} values of the acids, the equilibrim concentrations of and is dtermined using ICE tables.

What are acid dissociatio constants ?</h3>
An acid dissociation constant, of an acid is a measure of the strength of the acid in solution. The larger the value of an acid, the stronger the acid, therefore, acid dissociation constants are usually apply to only weak acids because strong acids have exceedingly large values.
It is written as a qoutient of the equilibrium concentrations of the aqueous species in the acid solution.
For the weak acids such as and , their equilibrim concentrations are determined using their values and an ICE table.
The pH of solutions are estimated using indicators such as methyl orange, methyl red and phenolphthalein. The colors of indicators change according to the pH of the solution
Acidic solutions have pH less than 7 while alkaline solutions have pH greater than 7.
Therefore, acids have low pH and weak acids have low values.

Answer:
Concentration
Explanation:
Amount of substance concentration often called simply concentration, is a quantitative measure of the number of atom s per unit volume in a sample of a matter.
