When it is treated with sodium ethoxide in deuterated ethanol (C2H5OD), 1,3-cyclopentadiene exchanges all of its hydrogens for deuterium. Draw a structure for the reactive intermediate that forms in this reaction in its hydrogen form.

Determine the  wavelength of light emitted when an electron  in an li2+ ion  makes a transition from an orbital with n  =  6 to an orbital with n  = 5.

They are like other investigations? say there was a murder u have to do blood test and finger prints which run through a lab. 

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

Deposition is the transition of matter going from gas to solid without passing through the liquid phase.a.) gas—-> solid
