This document discusses gas laws and properties related to gas pressure. It begins with questions about gas pressure in balloons and containers filled with pure oxygen. It then summarizes Dalton's law of partial pressures, which states that the total pressure of a gas mixture is equal to the sum of the individual gas partial pressures. The document provides examples of calculating total and partial pressures. It continues discussing vapor pressure and how to measure and correct for vapor pressure when collecting gases over water. It concludes with sample calculations for determining the volume of dry gas collected at standard temperature and pressure.
Dalton's law of partial pressure states that total pressure of the mixture of inert gases is equal to the sum of partial pressures of each gas present in the mixture.

The ideal gas law, also referred to as the general gas equation, is the equation of the state of the imaginary ideal gas. It is a good approximation of the behavior of certain gasses under several circumstances, although it has many drawbacks. It was first mentioned by Benoît Paul Émile Clapeyron in 1834 as a synthesis of the empiric law of Boyle, the law of Charles, the law of Avogadro, and the law of Gay-Lussac.

A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

2. How Much Pressure?
Q - A balloon is filled with pure oxygen. What is
the pressure of the oxygen in the balloon?
A - Atmospheric pressure. If it wasn’t, then the
balloon would expand or shrink.
Q - A windbag is blown up with exhaled air.
What is the pressure of oxygen in the bag?
A – Around 16 - 21% of atmospheric pressure
(O2 is 16% of exhaled air, 21% of atmosphere)
Q - A solid container is filled with pure oxygen.
What is the pressure in the container?
A - It could be anything. The container is solid
and therefore cannot shrink or expand.
3. Dalton’s law of partial pressures
Read pages 460 - 461
1. In the 18th century what did many scientists believe
about the earth’s atmosphere?
2. The % of which component of air varies the most?
3. Argon makes up about 0.93% of dry air. List the other
3 gases present in dry air (with their %s). Around what
% of dry air is made up by gases other than these 4?
4. Give Dalton’s law of partial pressures & the equation.
5. 1 L of N2 at 50 kPa is mixed with 1 L of O2 at 60 kPa, to
form a 1 L mixture of the gases. What is the resulting
pressure? What are the partial pressures?
6. A balloon contains 75 kPa N2, 15 kPa O2, 5 kPa CO2,
and water vapour. If atmospheric pressure is 100 kPa
what is the partial pressure of water vapour?
4. Dalton’s law of partial pressures
1. That the atmosphere was a single chemical
compound.
2. Water
3. N2: 78.08%, O2: 20.95%, CO2: 0.04%.
These add up to 100% of dry air, so there are
almost no other gases (really, 0.002%).
4. The total pressure of a mixture of nonreacting
gases is equal to the sum of the partial
pressures of the individual gases (Ptotal = P1 +
P2 + P3 + …)
5. Total pressure = 60 kPa + 50 kPa = 110 kPa
6. 100 - (75 + 15 + 5) = 100 - 95 = 5 kPa
5. Summary
Dalton found that the total pressure of mixed
gases is equal to the sum of their individual
pressures (provided the gases do not react).

100 kPa
150 kPa

This works according to the KMT because at the
same temperature molecules of different gases
have the same Ek. It doesn’t matter if the
molecules are O2 or H2. Both collide with the
container or other molecules with the same force.
6. Vapour Pressure Defined
• Vapour pressure is the pressure exerted by a
vapour. E.g. the H2O(g) in a sealed container.
Eventually the air above the water
is filled with vapour pushing down.
As temperature ↑, more molecules
fill the air, and vapour pressure ↑.
• Yet, molecules both leave and join the surface,
so vapour pressure also pushes molecules up.
• To measure vapour pressure we can heat a
sample of liquid on top of a column of Hg and
see the pressure it exerts at different °C.
7. Vapour pressure
Measuring Vapour Pressure
Vapour pressure for H2O
°C kPa °C kPa
10 1.23 50 12.33
20 2.34 75 38.54
Temperature
30 4.17 100 101.3
See pg. 464 for more
• When the vapour pressure is equal to the
atmospheric pressure (Patm), the push out is
enough to overcome Patm and boiling occurs.
• Thus, water will boil at a temperature below
100 °C if the atmospheric pressure is
8. Collecting gases over water
• Many times gases are collected over H 2O
• Often we want to know the volume of dry
gas at STP (useful for stoichiometry).
For this we must make 3 corrections:
1. The level of water inside and outside the
tube must be level (so pressure inside is
equal to the pressure outside).
2. The water vapour pressure must be
subtracted from the total pressure (to get the
pressure of the dry gas).
3. Finally, values are converted to STP using
the combined gas law.
9. Sample calculation
A gas was collected over 21°C H2O. After equalizing water levels, the volume was 325 mL. Give
the volume of dry gas at STP (Patm=102.9 kPa).
Step 1: Determine vapour pressure (pg. 464)
At 21°C vapour pressure is 2.49 kPa
Step 2: Calculate the pressure of dry gas
Pgas = Patm - PH2O = 102.9 - 2.49 = 100.41 kPa
Step 3: List all of the data
T1 = 294 K, V1 = 325 mL, P1 = 100.41 kPa
= 299 mL
Step 4: Convert to STP
(P1)(V1)(T2)
(100.4 kPa)(325 mL)(273 K)
V 2=
=
(P2)(T1)
(101.325 kPa)(294 K)
10. Assignment
1. 37.8 mL of O2 is collected by the downward
displacement of water at 24°C and an
atmospheric pressure of 102.4 kPa. What is
the volume of dry oxygen measured at
STP?
2. Try questions 8 – 10 on page 465.
3. 236 mL of H2 is collected over water at 22°C

4. If H2 is collected over water at 22°C and an
atmospheric pressure of 100.8 kPa, what is
the partial pressure of the H2 when the water
