A scientist measures the standard enthalpy change for the following reaction to be -1053.4 kJ : 2H2S(g) + 3 O2(g) 2H2O(g) + 2 SO2(g) Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of H2O(g) is
Using noble gas (n-1) dx representations write the outer electron configuration for the following ions
What is the gas pressure (in atm) inside a 1.69-L bulb that contains 0.9-g of Ne at a temperature of 34.1 C? Be sure to report the units as atm.
The normal boiling point of bromine is 58.8 C. Given that the vapor pressure pressure of bromine is 75.0 torr at 2.5 C, Calculate the molar enthalpy of vaporization of bromine.
Consider ATR sampling using a trapezoidal ZnSe crystal. In the mid-infrared region, refractive indices for ZnSe and water are approximately 2.4 and 1.3, respectively. What is the penetration depth (?m) for IR radiation of 1600 cm-1 if it strikes t..
A sample of cerium-141 for a diagnostic test was dissolved in saline solution to an activity of 4.5 millicuries/mL. If the patient undergoing the test needs a dose of 10 millicuries
How can you account for the difference between the colors of the benzaldehyde and cyclohexanone? Explain using formulas.
Chemists often use molarity ,M in Moles/liter , to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure
How many molecules of water are required to carry over 1 molecule of iodobenzene? How many grams of water per gram of iodobenzene?
2,2-dibromo-3-methylpentane can be prepared by an addition reaction of excess HBr with an alkyne. Draw the structure of the alkyne, name it, and write the reaction
These two solutions will be added together into a beaker to create one solution. Adding them together cause them to dilute each other. Calculated the new molarity of HX. Give your answer to four decimal places.
Calculate the sample of concentration. Is this an appropriate concentration for 1H NMR, 13C NMR or both?
Calculate the difference in pressure of 10.00g of carbon dioxide confined to a container of volume 100cm3 at 25.0 C between treating it as a perfect gas and a van der Waals gas.
