Chapter 11, Problem 1RQ
To determine
The forms in which clay is found
Expert Solution & Answer
Answer to Problem 1RQ
The forms of clay are surface clay, shales and fireclay.
Explanation of Solution
The different forms of the clay are surface clay, shales and fireclay.
Surface clay:
They are found near the surface of the earth and are strip-mined. Most of the bricks are made up of surface-mined clay.
Shales:
They are clays which are subjected to high pressure, due to which they become relatively hard.
Fireclay:
They are found at a higher depth and have more uniformity in their physical and chemical properties.

Question 6:
Chlorine is widely used to purify municipal water supplies and to treat swimming pool
waters. Suppose that the volume of a particular sample of Cl₂ gas is 8.70 L at 895 torr
and 24°C.
(a) How many grams of Cl₂ are in the sample?
⚫ Atomic mass of CI = 35.453 g/mol
• Molar mass of Cl₂ = 2 x 35.453 = 70.906 g/mol
Solution:
Use the Ideal Gas Law:
Step 1: Convert Given Values
• Pressure: P = 895 torr → atm
PV=
= nRT
1
P = 895 ×
= 1.1789 atm
760
•
Temperature: Convert to Kelvin:
T24273.15 = 297.15 K
• Gas constant: R = 0.0821 L atm/mol. K
Volume: V = 8.70 L
Step 2: Solve for n
.
PV
n =
RT
n =
(1.1789)(8.70)
(0.0821)(297.15)
10.25
n =
= 0.420 mol
24.405
Step 3: Calculate Mass of Cl₂
Final Answer: 29.78 g of Cl₂.

mass=
(0.420)(70.906)
mass=
29.78 g

1. Design a PVC sanitary sewer collection system for the Village of Waffle (Figure P-17-24 B, shown below) by
preparing a sewer design table similar to that shown in Example 19-2 and a profile drawing similar
to Figure 19-13b B. You only need to show the calculations for the pipes running along Bacon Road and
Eggs Road, starting at point F and ending at Point B in the figure below. Your design should comply with the
requirements specified in Chapter 30 of the 10 States Standards for Wastewater. Use the following
assumptions:

Average daily flow rate is the same as average daily water demand, 9.2 m³/hr
Peaking factor for peak dry weather flow is 6.2
Peak wet weather flow is equal to the peak dry weather flow plus an assumption for infiltration and inflow

In a truss structure, connections are theoretically assumed to act as smooth pin; therefore, it does not resist any moment or bending. Due to this magnificent behavior, truss members only resist axial forces in the design phase that could either be compressive or tensile.

A recent daytime crash (driver traveling westbound and striking a stationary roadway object) resulted in a fatality and a lawsuit alleging that the 100 km/h posted speed limit is an unsafe speed for the curves in question and was a major cause of the crash.
