NEEDED ASAP WITH CLAIM EVIDENCE AND REASONING CER Scenario: During volleyball practice, the coach recorded how high the girls were able to hit their volleyballs into the air. When practice was
over, the girls complained that their hands hurt. The coach asked them to
rate their pain on a scale of one to five, and then developed this graph.
The graph shows the relative distance their volleyballs traveled versus
how much pain the girls reported. Prompt: Using Newton's third law of
motion, write a scientific explanation that describes why Mandy
experienced more pain than the other girls. *

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.

Many ionic compounds and a few highly polar covalent compounds are because they completely ionize in water to create a solution filled with charged ions that can conduct an electric current.

Use the periodic table to find the molar mass of each element. molar mass h = g/mol molar mass s = g/mol molar mass o = g/mol
