Suppose you take a trip to a distant universe and find that the periodic table there is derived from an arrangement of quantum numbers different from the one on Earth. The rules in that universe are:
Write the electron configuration with the atomic number 8 in the periodic table?
Calculate the amount of acid that would be left in the water solution after four 20-mL extractions with ether. Do the same calculation, using one 80-mL extraction with ether, to determine which method is more efficient.
An electron in an excited state of a hydrogen atom emits two photons in succession, the first at 1281 nm and the second at 102.5 nm, to return to the ground state (n=1).
A 0.100M (as prepared) solution of dichloroacetic acid has an observed [H30+]= .043 M. What are the equilibrium concentrations and the value of the equilibrium constant for the reaction shown?
A chemist dissolves 128 mg of pure hydrobromic acid in enough water to make up of 110 mL solution. Calculate the pH of the solution.
Write a balanced net ionic equation for the neutralization reaction and Tartaric acid,( C4H6O6) , has two acidic hydrogens.
Determine the numbers of oxygen molecules are required for each molecule of C 6 H 12 O 6 glucose that is oxidized if Glucose is oxidized by molecular O 2 to CO 2 and H 2 O?
the energy is 18.44 kj/mol and for the methyl group in equatorial position the energy was 8.66 KJ/mol based on this information which is more stable and why?
Conductivities are often measured by comparing the resistance of a cell filled with the sample to its resistance when filled with some standard solution, such as aqueous potassium chloride. The conductivity of water is 76 mS m^?1 at 25°C
A 150.0-g sample of a metal at 75.0 °C is added to 150.0 g of H2O at 15.0 °C. The temperature of the water rises to 18.9 °C. Calculate the specific heat capacity of the metal, assuming that all the heat lost by the metal is gained by the water.
How much ice in grams would have to melt to lower the temperature of 51.0 g of water from 65.0*C to 0*C
Calculate the molar solubility of CaCO3 ( Ksp = 4.5*10-9) neglecting the acid-base character
Given the values of ΔH ° rxn , ΔS ° rxn , and T below, determine ΔS univ. ΔH ° rxn = 80kJ , ΔS rxn = 143J/K , T= 299K Express your answer using two significant figures.
