Answer:
Explanation:
Filtration can be used to separate an insoluble solid from a liquid, or a precipitate from the reaction mixture in which it formed. The solid which collects in the filter paper is called the residue. The clear liquid which passes through the filter paper is called the filtrate.
Answer:
Diluting an acid reduces the concentration of the H+ ions that cause acidity, while diluting a base reduces the concentration of the OH- ions that cause basicity.
Explanation:
The pH scale covers a range between 0 and 14 pH. A pH of exactly 7 is neutral. pH values greater than 7 are basic, while pH values less than 7 are acidic. The pH scale is logarithmic with a base of 10, meaning each integer pH value is 10 times more acidic or basic than the one preceding or succeeding it respectively. For dilution to decrease the acidity or basicity of a solution, the solvent being used must be less acidic or basic than this solution.
Alternatively, an acidic diluent may be used to dilute a basic solution, or vice versa, in a neutralization reaction. Because of the logarithmic nature of the pH scale, diluting a strong acid or base even slightly causes its respective pH to rise or drop considerably. Weak acids and bases with pH values close to 7 are correspondingly not as affected by dilution.
The final temperature of the mixture will be <u>30⁰C</u>
Since it is given that 50 gms of water at 20 ⁰ C and 50 gms of water at 40⁰ C are mixed. Since the masses of the liquid at different temperatures are the same, the answer is very easy and simple: average of 20⁰C and 40⁰C. that is 30⁰C.
<em>the final temperature of the mixture = </em>
<em> = [ m1 * T1 + m2 * T2 ] / (m1 + m2)</em>
<em> = [ 50 gms * 20⁰ C + 50 gms * 40⁰C ] / (50+50)</em>
<em> </em><em> = 3,000 / 100 = </em><u><em>30⁰C</em></u>
In chemistry, we define the temperature of a substance as the average kinetic power of all of the atoms or molecules of that substance. No longer do all of the debris of a substance have identical kinetic strength. At any given time, the kinetic energy of the debris may be represented by means of a distribution.
Temperature performs a vital function in-hospital treatment (both humans and animals), food, beverages, and agriculture. Our average fitness is regularly reliant upon the temperature in lots of methods as nicely.
The SI unit of temperature as consistent with the global system of devices is Kelvin.

<span>Get into moles first. .0590 grams over 540.8 grams per mole = 1.09 x l0^-4 moles
Sr3(As04)2 = 3 Sr++(aq) plus 2 As04^-3(aq)
Ksp = (Sr++)^3(As04^-3)^2
(Sr++) = 3 X l.09 x l0^-4 = 3.27 x l0^-4
(As04^-3) = 2 x l.09 x l0^-4 = 2.18 x l0^-4
<span>Ksp = (3.27 x l0^-4)^3 (2.18 x l0^-4)^2 which equals 1.66 x 10^-18th
