(a)
Interpretation:
The flow-chart for the given process is to be drawn and labeled.
Concept introduction:
A flowchart is the complete representation of a process through boxes or other shapes which represents process units and arrows that represents the input and output of the process. The flowchart must be fully labeled to infer important data about the process involved.
(b)
Interpretation:
The balanced equations about the egg sorter on total eggs and broken eggs are to be written and solved.
Concept introduction:
In a system, a conserved quantity (total mass, mass of a particular species, energy or momentum) is balanced and can be written as:
Here, ‘input’ is the stream which enters the system. ‘Generation’ is the term used for the quantity that is produced within the system. ‘Output’ is the stream which leaves the system. ‘Consumption’ is the term used for the quantity that is consumed within the system. ‘Accumulation’ is used for the quantity which is builds up within the system.
(c)
Interpretation:
Numbers of large eggs that leave the plant per minute along with the fraction of its broken eggs are to be calculated.
Concept introduction:
Fraction of any particular species is defined as the ratio of that species to the total quantity. Mathematically it is written as:
Here,
(d)
Interpretation:
The employee Chick is whether right- or left-handed is to be determined.
Concept introduction:
A person is either right- or left-handed is based on the effectiveness of the work done by both the hands. The fraction of spoiled work is taken as the basis to decide the handedness of a person.

- environmental chemist working for the Environmental Protection Agency (EPA) was directed to collect razor clams from a heavily-contaminated river superfund site and analyze them for cadmium (Cd²+) content using graphite furnace atomic absorption spectrometry (GFAAS). The chemist dried the clams at 95° C overnight and ground them in a scientific blender, resulting in ~ 50 g of homogenized dry weight. A representative 61.00 mg sample was taken from the ~ 50 g of dry material and dissolved in 100.00 mL of 0.1 M HCI to create a sample solution. Using the method of standard additions, the chemist prepared five standard solutions in 100.00-mL volumetric flasks, each containing 5.00-mĹ aliquots of the sample solution. Varying amounts of a 87.0 ppb (ug · L-1) cadmium standard were added to each of the flasks, which were then brought to volume with 0.1 M HCI. The solutions were then examined for their Cd²+ content using GFAAS, resulting in the following absorbance data.

Round your answer to two decimal places.arrow_forwardAmylum, commonly known as starch is a white powder with variable molecular formula due to the different number of repeating sugar units based on the plant that it is obtained from. A sample of amylum in the form of spherical beads was subjected to series of analyses to determine physicochemical properties in the quality control unit of a factory. From the results each bead is found to have a 4.5 mL volume and 1.47 g/mL density. 4 of the beads were placed in a reaction chamber combusted, as a result, 43.1 g CO2 and 14.7 g H2O were obtained. If the molecular weight of the amylum is 972.84 g/mol how many repeating units the starch molecule consist and what is the molecular formula of the starch?
