Explanation Given: Wave length of photon is 2 .3×10 -3 m . The amount of heat = 74 kJ Wavelength: Wavelength of any wave is the distance between consecutive peaks or troughs. It is denoted by ?. The unit of wavelength is meter, cm, nm, mm etc. Frequency: Frequency of any wave is the number of oscillations per second means the number of oscillation in one second. It is denoted by ?. The unit of frequency is per second. Its SI unit is Hz, which is equal to s − 1 . Formula used: c=λν v= c λ λ= c v Here, v=frequency, λ=Wavelength and c= Velocity or speed Calculation: Calculate the energy of one photon as follows: E=h c λ E=6 .626×10 -34 J× s × 3 .0×10 8 m s -1 2 .3×10 -3 m =8

The electrons flow from the electron-rich atoms of the nucleophile to the electrons poor atoms of the alkyl halide. Identify the electron rich in the nucleophile. Enter the element symbol only, do not include any changes.

Hello, I am doing a court case analysis in my Analytical Chemistry course. The case is about a dog napping and my role is prosecution of the defendant. I am tasked in the Area of Expertise in Neutron Activation and Isotopic Analysis. Attached is the following case study reading of my area of expertise! The landscaping stone was not particularly distinctive in its decoration but matched both the color and pattern of the Fluential’s landscaping stone as well as the stone in the back of the recovered vehicle. Further analysis of the stone was done using a technique called instrumental neutron activation analysis. (Proceed to Neutron Activation data) Photo Notes: Landscaping stone recovered in vehicle. Stone at Fluential’s home is similar inappearance. Finally, the white paint on the brick was analyzed using stable isotope analysis. The brick recovered at the scene had smeared white paint on it. A couple of pieces of brick in the back of the car had white paint on them. They…
