Problem- Begining with sodium acetylide (NaCCH), propose a three-step synthesis of hexanal.
I just need a general explanation of it please- Thanks!
Problem- Li can be determined by flame atomic absorpion spectrophotometry at 670.8 nm. How is this possible, given the strong Li emission from the flame at this wavelength
When 28.0 ml of 0.500 M H2SO4 is added to 28.0 ml of 1.00 M KOH in a coffee-cup calorimeter at 23.50 degrees Celsius, the temperature rises to 30.17 degrees Celsius. Calculate the delta H of this reaction.
A 93-L sample of dry air cools from 145 degrees celicus to -22 degrees celicus while the pressure is maintained at 2.85 atm. What is the final volume?
Calculate the mass of ammonia formed when 6 g of hydrogen react with 14 g of nitrogen to form ammonia. You may use whole numbers for atomic masses.
Calculate the separation in energy between the ground state and the first excited state in which one electron occupies the state with n=7. Calculate the frequency of the radiation required to produce a transition between these two states.
The potential energy of water at the top of a dam or waterfall is converted into heat when the water dashes against rocks at the bottom. The potential energy of the water at the top is equal to Ep=mgh, where m is the mass of the water, g is the ac..
Describe fluorescence and phosphorescence. Use PE curves to help compare and contrast the two terms. Also discuss why the two occur on different timescales and indicate portions on the PE curve
Two scientists are experimenting with pure samples of isotope X, a highly radioactive substance. The first scientist has a sample with a mass of 20 grams.
Sketch a titration curve of what the titration of the dry acid vs. sodium hydroxide might look like and explain the diagram.
