ACTIVITY 2.: MYSTERY WORD DIRECTION: Arrange the jumbled letters to form the word that corresponds to its
description.
VRETSRSANE EWVA
Hint: It is a wave in which the direction of the wave's propagation is perpendicular to
the direction of the particles displacement
ECMAHLINAC EVAW
Hint: It is the wave which propagates only in a material or medium.
ALNIDUTGLONI WVEA
Hint: A mechanical wave whose particle displacement is parallel to the direction of
the waves propagation.
LROCGTNEAMECITE EAVW
Hint: It is a wave which does not necessary requires a material medium for its
propagation and own also travel through a vacuum.

A3.37-mg sample of protein was chemically digested to convert its nitrogen into ammonia and then diluted to 100.0 ml. then 10.0 ml of this solution was placed in a 50-ml volumetric flask and treated with 5 ml of phenol solution plus 2 ml of sodium hypochlorite solution. the sample was diluted to 50.0 ml, and the absorbance at 625 nm was measured in a 1.00-cm cuvette and found to be 0.486. for reference, a standard solution was prepared from 10.0 mg of nh4cl (molar mass = 53.49 grams/mole) dissolved in 1.00 l of water. then 10.0 ml of this standard was placed in a 50-ml volumetric flask, treated in the same manner as the unknown, and the absorbance found to be 0.323. finally, a reagent blank was prepared using distilled water in place of unknown, it was treated in the same manner as the unknown, and the absorbance found to be 0.076. calculate the weight percent of nitrogen in the protein.
