In order to dispose of chemical waste, a waste ticket must be filled out listing all chemical components as a percentage.

This requires the use of conversion factors to convert the concentration of compounds into a percentage and list them on the waste ticket. When filling out waste tickets, each chemical is listed as less than or equal to ( ≦) its percentage. Water, or whatever solvent is used, is listed as ≧ the remaining percentage.

Us the information below, along with the information given in the prior questions for making Reagents A & B for nitrate assays to correctly fill out the waste ticket below.

Reagent A, the N-(1- Naphtyl) ethylenediamine solution (NNED Solution) contains 1 g L ^-1 NNED, as described in an earlier question.

Reagent B, the S ulfanilamide Solution, contains 10 g L Sulfanilamide , and has an HCl concentration of 2.4 M as described in an earlier question. The formula weight of HCl is 36.46 g mole^-1.

Every sample is 8 mL, and shaken for 5 minutes with 0.1 g of cadmium powder prior to being mixed with 1 mL of Sulfanilamide solution and 1 mL NNED Reagent.

For this experiment, 60 samples and 5 standards were processed. The cadmium powder is insufficient to change the volume of the sample. Assume the samples have a total nitrate concentration ≦ 0.01%.

Given the above information, complete the waste ticket below for the chemical waste from performing Nitrate Assays in this experiment.

Remember to consider the reagents were diluted when they were mixed with the sample.

Remember to calculate percentages as mass in grams over total volume (650 mL).

Round all answers to TWO decimal place.

2. Two firms propose to dispose of all of the waste currently entering the City of Columbia landfill. Each proposal is to handle the waste stream for 10 years. The current estimate is for about 220,000 tons of trash per year. Both firms’ minimum acceptable rate of return is 5 percent. Firm #1: Wants $3 million dollars up front and will bill the City at $32/ton of waste for the 10-year period. Firm #2: Wants $1.5 million up front and...

A polyhedron must meet three conditions in order to be regular: All of the faces are regular polygons; All of the faces are congruent (identical); All of the vertex points/arrangements are congruent (identical). Try to find three nonregular polyhedra, each of which violates a different one of these conditions. In other words, one of them should meet (1) and (2) but not (3); one should meet (1) and (3), but not (2); one should meet (2) and (3) but not...
