Explain whether you expect the bond in each molecule to become stronger, weaker, or unchanged upon 1-electron oxidation and 1-electron reduction (HCL HF)
What are the RATE LAW and k VALUE (with units) for the reaction? Assume conc. in moles per liter T or F. Feezer burn involves solid water conversion to vapor then back again.
Inside a bomb calorimeter with a total heat capacity of 11.30 kJ/oC. 1.50 g sample of methane gas "CH4" was burned with excess oxygen. The temperature increased inside the calorimeter by 7.3oC.
Three 5.00mL samples of this solution are titrated with DCP that had a standardized concentration of 9.94x10-4M. The three titrations took an average of 27.51mL of DCP. (MM Ascorbic Acid = 176.124 g/mol) Calculate the mass (in mg) in the vitamin C ..
The vapor pressure of pure ethyl bromide at this temperature is 400.0 torr. Assuming an ideal solution, what is the molecular mass of the compound?
The temperature scale is called °M and has a value of 0°M at the freezing point and 100°M at the boiling point of ethylene glycol. What would the temperature be in degrees centigrade, if it was 20.916°M
Write balanced net ionic equation for the neutralization of equal molar amounts of HBr and NH_3
If the mixture is ignited and the methane completely combusts, producing carbon dioxide (CO2) and water (H2O), calculate the mass percent, the mole fraction, and the partial pressure of CO2 in the container after cooling back down to the initial t..
Based on this equation, what is the value of the Rydberg constant (R) in m-1? (5 significant figures)
Write equations to show how a buffer made up of equimolar amounts of acetic acid, CH3COOHm and acetate, CH3COO-, would behave when (a) HCl is added and (b) NaOH is added.
In what ways might the one(s) that does (do) not have a metabolic energy source (caffeine) provide the perception of increased energy after consumption?
