I need name of the final compound, and step by step equations of the reaction for the experiment below. Ethylenediamine complexes of Cobalt Procedure 1. Dissolved 1.5 g CoCl2 in 5mL water 2. While the CoCl2 6H2O is dissolving, measure out 10mL of an ethylenediamine solution. (The solution is prepared by dissolving 130mL of anhydrous ehylenediamine in one liter of water) 3.Cool the ethylenediamine solution in ice. 4.Slowly add 2.1mL 3M HCl 5.Add the CoCl2 solution to the partially neutrolized ethylenediamine and then slowly add 2mL of 30% H2O2 with stirring 6.Stir until effervescence ceases. 7.Place the mixture on a hot plate and allow to boil gently 8.When the cobalt solution is evaporated the a volume of 6 to 10mL, add and equal volume of concd. HCl and twice the amount of ethyl alcohol. 9.Cool, filter, press dry on the sintered glass funnel. Thanks.

(a) Name 4 major components of a Gamma camera. Briefly explain
the function of each component.
Also, describe the advantages and disadvantages of using “thin”
scintillating crystal.
(b) In an experiment with 51.80 MBq 99mTc, 5.88×105 counts are measured in 2 minutes. According to the manufacturer the sensitivity is 202 cnts/(min⋅μCi) (American manufacturers still use Ci instead of Bq, 1μCi = 37 kBq). What is the difference between the sensitivity of the measurement and the factory specification?
(c) in a NM scan, we use a specific contrast agent with half-life
of 2h and emitted gamma radiation with wavelength of the 8.79x0-12
m. We image the patient immediately after the injection and the
scan takes 20 minutes. Injecting 1 mCi, the acquired NM images have
signal-to-noise ratio of 40. Calculate the SNR if we inject the
patient with 3 mCi and scan him for 60 minutes.

A compound contains only carbon, hydrogen, nitrogen, and oxygen. Combustion of 0.157g of the compound produced 0.213g CO2 and 0.0310g of H2O. In another experiment, 0.103g of the compound produced 0.0230g of NH3. What is the emerical formula of the compound? In a seperate experiment, the molar mass is found to be 454.3 g/mol. what is the molecular formula of the compound? hint: assume that all carbon ends up in CO2 and all hydrogen ends up in H2O.Also assume that all nitrogen ends up in the NH3 in the second experiment

1)In the experiment to investigate Newton's second law
of motion by using linear air track,explain the function of each
apparatus used,which are air track rail,blower,pressure
tubr,gliders,flag,photogate,string and pulley.
2)Why do we need to measure the length of the flag to
get the accelerationnand why do we use the formula a=2X/t2?.
3)Is there any friction force involves and suggest the ways to improve this experiment

Using DNase footprinting, show that the sigma subunit of prokaryotic RNA Pol binds to nucleotides from -35 to -10 in the promoter region.
a. Outline your experiment and draw and label the data. Explain how your data support this conclusion.
b. Show and label the data for a similar experiment done using DMS footprinting rather than DNase foot printing. Explain how your data support this conclusion. You do NOT have to write out the experiment again.
