Question
Chapter 3, Problem 3.1Q
Interpretation Introduction
Interpretation:
Thecorrect word for the given statement should be determined.
Concept Introduction:
Chemical bond is an attractive force between the constituent atoms. It holds the atoms together in a molecule.
The bonds are classified as: Ionic bond and Covalent bond.
An ionic bond is formed between the metal and non-metal. Such compounds are known as ionic compounds.
A covalent bond is formed by sharing the electrons by the atoms. Such compounds are known as covalent compounds.
The interaction of two carbon atoms is due to the sharing of electron pairs such that a stable chemical bond can be formed.
Expert Solution & Answer
Answer to Problem 3.1Q
A bond between two carbon atoms is a covalent bond.
Explanation of Solution
Given information:
A bond between two carbon atoms is a ______ bond.
A carbon atom has four valence electrons in the outer shell and requires eight electrons to achieve a stable state. When two carbon atoms come together, they share unused electrons to form bonds. Such bonds are called chemical covalent bonds. There can be single, double or triple covalent bonds depending upon the valence electron requirement.
In this context, H3C-CH3 is an example of a single bond, H2C=CH2is an example of double bond and
Conclusion
The carbon atoms are linked with covalent bond.

- 1 5) You are asked to design a moving bed adsorption process using two columns (see the figure below). Your feed contains 100 mg/L protein and flows through both columns at 4 m³/h. Fresh resin enters the bottom of both columns (resin does not flow from the bottom column to the top column). The maximum resin flow rate that your pumps can comfortably handle is 120 kg resin/h. Experimental data suggest that the adsorption equilibrium can be modeled as qi=4ci where qi is in g protein/kg resin and c; is in g protein/L broth. (Pay attention with units!) a) What is the lowest concentration of proteins that you could get in the effluent from column 1 (indicated by the *) in mg/L?

Your column is 25 cm long with an inner diameter of 5 cm. The resin packed in the column has a density of 1.5 g/cm³ and a void fraction of 0.25. Equilibrium data suggests that the protein binding to the column follows a Langmuir isotherm with an Stot = 6.25 g protein/kg resin and Keq = 2.58 L broth/g protein. The feed contains 100 mg/L protein and flows through the column at 500 mL/h. The calculated binding capacity of the column under these conditions is 945 mg protein. a) After 17.7 h, you detect an unacceptable level of protein in the column effluent. What is the length of unused bed? b) After deciding that this process will work well for separation, you need to scale up to a 1 m long column with the same diameter.

- Chemical Engineering Use the psychrometric chart and demonstrate the linear interpolation method to obtain -0.52 KJ/KgDA. This is the enthalpy deviation. The exercise is uploaded below.arrow_forwardChemical Engineering Use the psychrometric chart. The remaining curves on the psychrometric chart are almost vertical and convex to the left, with labeled values (on Figure 8.4-1) of 0.05, 0.1, 0.2, and so on. (The units of these numbers arekJ/kg DA). Thesecurves are usedto determine theenthalpyof humid air that is not saturated. The procedure is as follows: (a) locate the point on the chart corresponding to air at its specified condition; (b) interpolate to estimate the enthalpy deviation at this point; (c) follow the constant wet-bulb temperature line to the enthalpy scale above the saturation curve, read the value on that scale, and add the enthalpy deviation to it.
