Among the solubility rules previously discussed is the statement: Carbonates, phosphates, borates, and arsenates-except those of the ammonium ion and the alkali metals-are insoluble.
(a) Write the expression for the equilibrium constant for the reaction represented by the equation
CaCO3(s) ? Ca2+(aq) + CO3 -(aq). Is Kc > 1, < 1, or ≈ 1? Explain your answer
which concept would explain why the carbon to carbon bond lengths in benzene c6h6 are identical? ahybridization blondon
why is tert-butyl methyl ether not expected to be a good solvent for polyhydroxylated carbocycles glucose and fructose
if your air conditioner is more than several years old it may use the chloroflurocarbon ccl2f2 as the heat transfer
Can metal ions be separated by slowly adding Na2CO3. Assume that for successful separation 99% of the metal ion must be precipitated before the other metal ion begin to precipitate, and assume that no volume change occurs on addition of Na2CO3
The solubility of CO2 in water at 25°C and 1 atm is 0.034 mol/L. What is its solubility under atmospheric conditions. (The partial pressure of CO2 in air is 0.0003 atm.) Assume that CO2 obeys Henry's law.
This experiment focused on a carbonyl group converted to an imine and then to an amine. Explain what spectroscopic techniques you could use to identify the progress of this reaction
What is Kd of a substance X if 25 ml of a 0.015 M aqueous solution of X is extracted with 10.0 ml of ether. The entire 25 ml of water (aqueous solution) is titrated and it is found that the concentration of X after extraction is 0.005 M. The molar..
Why does aluminum hydroxide readily dissolve in concentrated NaOH but not in concentrated NH3. Please give a thorough explanation, not just a short answer.
The colors of the acid and base forms of the indicator bromocresol green are yellow and blue, respectively, and its pKa is 4.6. What color would be expected for the indicator in a solution of pH 6.0 and in a solution of pH 4.8?
Which side left or right does the equilibrium lay for the subsequent reaction as well as explain the reason- CH3COOH (pKa =4.8) + NH3 Û CH3COO-_ + NH4+
It is desired to inflate a baggie with a volume of 959 milliliters by filling it with hydrogen gas at a pressure of 0.544 atm and a temperature of 284 K. How many grams of H2 gas are needed?
The activity of a radioactive sample is the number of nuclear disintegrations per second, which is equal to the first-order rate constant times the number of radio-active nuclei present.
