Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.

2. What happens when
Metals are burnt in Air ?
1. Almost all metals combine with
oxygen to form METAL OXIDES
2. Metal oxides are basic in
nature
3. Metal oxides which react with
both acids as well as bases to
produce salt and water are
known as AMPHOTERIC OXIDES
4. Most metal oxides are
insoluble in water but some of
these dissolve in water to form
ALKALIS
5. All metals do not react with
oxygen at the same rate
3. What happens when
Metals react with Water ?
1. Metals react with water and produce
a metal oxide and hydrogen gas.
Metal oxides that are soluble in
water dissolve in it to further form
metal hydroxide
2. All metals do not react with water
3. In case of sodium and potassium,
the reaction is so violent and
exothermic that the evolved
hydrogen immediately catches fire
4. The reaction of calcium with water is
less violent. Calcium starts floating
because the bubbles of hydrogen
gas formed stick to the surface of
the metal
5. Magnesium reacts with hot water to
form magnesium hydroxide and
hydrogen
6. Metals like aluminium, iron and zinc
react with steam to form the metal
4. What happens when
metals react with acids ?
1. Metals react with acid to give
hydrogen gas and form metal salts
Metal + Dilute acid→Salt +
Hydrogen
2. The rate of formation of
bubbles was the fastest in the
case of magnesium. The
reaction was also the most
exothermic
3. The reactivity decreases in the
order Mg > Al > Zn > Fe
4. No bubbles were seen and the
temperature also remained
unchanged when reacted with
copper. This shows that copper
does not react with dilute HCl
5. METALS + SALT
SOLUTIONS
How do Metals react with
solutions of other Metal Salts ?
1. We checked the reactivity of
various metals with oxygen,
water and acids. But all metals
are not equally reactive
2. Displacement reactions gives
better evidence about the
reactivity of metals
3. Reactive metals can displace
less reactive metals from their
compounds in solution or
molten form
4. It is simple and easy if metal A
displaces metal B from its
solution, it is more reactive
than B
Metal A + Salt solution of B → Salt
solution of A + Metal B
