Fundamentally, why would any line in the hydrogen spectrum between 250 nm and 700 nm belong to the balmer series? How much energy in kj per mole does it take to ionize an H atom? The ionization energy of hydrogen is often expressed in units other than kj/mole. What would it be in joules per atom?
We had to do an experiment that depolymerized PET into terephthalic acid and ethylene glycol using 1-pentanol and KOH. One of the post-lab questions is as follows:
A new catalyst is being developed with the hope of generating ethylene by the oxidative dehydrogenation of ethane, reaction (1). Two side reactions accompany the main reaction;
Container A (with porous walls) is filled with air at STP. It is then inserted into a large enclosed container (B) which is then flushed with H2(g). What will happen to the pressure inside container A?
Treatment of an aldehyde or ketones with hydrazine, H2NNH2, yields an azine, R2C=N-N=CR2. Propose a mechanism
Calculate the volume in liters occupied by 0.350 moles of propane gas at a pressure of 0.850 atmospheres
During a lab experiment, we were to determine the relative level of saturation by adding, drop by drop, a solution of bromine in cyclohexane to oil and a fat, individually. However, the color that is supposed to be retained due to unreacted bromin..
What is the silver ion concentration for a saturated solution of Ag2CO3 if the Ksp for Ag2CO3 is 8.4 x 10^-12
separation and purification scheme 50% toluic acid, 40% fluorene, 10% 1,4-dibromobenzene
The average concentration of calcium ion in seawater is 412 mg of calcium ion per kg of seawater. What is the molarity of the calcium ion if the density of the seawater is 1.025 g/mL?
How many moles of oxygen atoms are combined with 4.20 moles of chlorine atoms in Cl2O7?
reaction does k decrease over time what about in a 0 and 1 st order reaction. In a second order reaction does the half life increase over time what about in a 0 and 1 st order reaction?
A researcher working on a batch of a ceramic material tested two sets of samples for fracture strength. For one set of samples the specimens were tensile bars with a 10x10x100 mm^3 tensile gauge section
