Write down the expression for the radial distribution function of a 3p electron in a hydrogenic atom and determine the radius ar which the electron is most likely to be found
total ion concentration what conductivity should be observed for 0.050 M Na2SO4?
In spectroscopy, the ratio of the intensity of radiation that passes through (I) the sample and the intensity of the radiation (Io) that is directed at the sample being analysed is called
Diamonds are measured in carats where 1 carat= 0.200 g. The density of diamond is 3.51 g/cm^3. What is the volume of a 2.50-carat diamond
What volume of O2 at 684 mmHg and 21 degree celsius is required to synthesize 25.0 mole of NO?
Determine the molar concentration of the original acid solution and find pH and a % ionization of the acid in the original solution.
Draw sodium formate by placing atoms on the grid and connecting them with bonds. Include all lone-pair electrons.
A sample of neon gas used in a neon sign occupies a volume of 1.70 L at a pressure of 580 torr. Calculate the volume of the gas if the pressure in the glass tube of the sign is 781 torr.
Calculate the volume of ammonia required to bring the pH to 3.00 and to 8.00. Kb (NH3) = 1.8 x 10^-5.
Claisen reactions use a stoichiometric amount of base and do not polymerize, unlike aldol reactions that use a catalytic amount of base and can polymerize.
A 330 mL container holds 0.146 g of Ne and an unknown amount of Ar at 35°C and a total pressure of 626 mmHg. Calculate the moles of Ar present.
The spectrophotometer is to be set at 447nm. What experiment could you do, what data would you collect
A 0.0100 L sample of H2SO4 (Sulfuric Acid) was titrated with 0.150 M NaOH. It took 23.3 mL of NaOH from the buret -- that's 0.0233 L -- to reach the titration endpoint.
