Hydrocarbon Compound with only carbon and hydrogen
Organic chemistry involves the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds, which include not only hydrocarbons but also compounds with any number of other elements, including hydrogen (most compounds contain at least one carbon–hydrogen bond), nitrogen, oxygen, halogens, phosphorus, silicon, and sulfur.
This branch of chemistry was originally limited to compounds produced by living organisms but has been broadened to include human-made substances such as plastics. The range of application of organic compounds is enormous and also includes, but is not limited to, pharmaceuticals, petrochemicals, food, explosives, paints, and cosmetics.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

6. Carbon or Organic compounds
•Organic compounds are group of compounds that
contain the element carbon.
•Some carbon compounds are produced by plants
and animals. However, these carbon-containing
compounds can also be produced artificially.
•
8. • Gasoline – strong odor, volatile, highly flammable
• Lubricating oil - viscous thus used to lubricate parts of
machines, instruments, or appliances such as motor of
electric fan; and protect metals from rusting
• Kerosene and ethyl alcohol. Flammable liquids such as
kerosene is used as fuel for lamps (gasera) and portable
stove (kusinilya). Although ethyl alcohol is also
flammable, it is not used as fuel for stoves or lamps only.
It is also used as a component of biofuels for vehicles, as
an ingredient for liquors, and as a disinfectant.
9. recall
• How do atoms of non-metal elements form their
compounds?
By bonding through sharing of electrons with other elements or
with same elements
What type of bonds do nonmetals form in
compounds?
Single bond, double bond, triple bond
10. TERMINOLOGIES
• Structural formula is a formula for a molecular
compound that indicates the atoms present and the
bonding sequence of the atoms. The covalent bonds
between atoms are conveyed as lines connecting the
symbols of the bonded atoms. This formula gives a
clear illustration about the structure of a compound.
• Condensed Formula is a formula for a molecular
compound that indicates the bonding sequence
without showing all the bonds. It should be clear that
the carbon atoms are bonded together in sequence,
and each carbon is bonded to the hydrogen atoms
next to the formula.
• Boiling point is the temperature at which a liquid
evaporates or becomes vapor
11. Hydrocarbons
•Hydrocarbon – compound that contains
only the elements carbon and hydrogen
• Hydrocarbons mix poorly with water
• All hydrocarbons are flammable; CH4 (methane), C2H6 (ethane), C3H8
(propane)
12. • Carbon atoms can form single, double or
triple bonds with other carbon atoms.
• Carbon can form up to 4 bonds
• This allows carbon atoms to form long
chains, almost unlimited in length.
• Carbon can bond with other carbons, form
straight chains, branched chains and rings
13. • Hydrocarbons such as methane, ethane and butane are
components of natural gas.
• Hydrocarbons are grouped into families namely, alkanes,
alkenes and alkynes.
Hydrocarbons
14. GROUP ACTIVITY
• Objectives:
• Recognize common kinds of alkanes, alkenes, and
alkynes and their uses.
• Identify the types of bonds formed in alkanes, alkenes,
and alkynes.
• Relate the structures of alkanes, alkenes, and alkynes to
their properties.
16. Guide Questions
What are the types of bonds present in the following:
alkanes, alkenes, and alkynes?What pattern do you
observe in terms of the phase, number of carbon atoms,
structure and boiling point of the alkanes, alkenes, and
alkynes?
18. Structure of Hydrocarbons
• Saturated hydrocarbons – only single bonds, has maximum
number a hydrogen atoms attached
• Unsaturated hydrocarbons – has double or triple bonds, have
fewer hydrogen than saturated hydrocarbons
19. • Methane gas – most
common hydrocarbon
-fuel for cigarette lighters and
LPG
• Butane gas- also used as fuel
Blue flame in cigarette lighter
Ethyne gas (acetylene)– for
hastening the ripening of
fruits
Used in flame torch
• Octane and pentene
– components of gasoline
-Common liquid hydrocarbons
20. Using calcium carbide (kalburo) makes the ripening of bananas faster than
without using calcium carbide. This is because when calcium carbide
(kalburo) reacts with the moisture in the air, acetylene gas is produced.
Acetylene gas is the compound that makes the ripening of the fruits becomes
faster. Acetylene imitates the action of the natural ripening agent called
ethene or ethylene (C2H4). Ethene or ethylene is a plant hormone that
regulates activity of the genes that are responsible for the ripening of fruits.
21. ALCOHOLS
Alcohols are another group of organic compounds.
Some alcohols are used as antiseptic or
disinfectant,some are used as cleaning agents, others
are used as components of liquors and a few alcohols
are used as fuel for portable stoves or other types of
burners.
24. Acetone
• Molecular FormulaC3H6O
or CH3-CO-CH3 or CH3COCH3
• It is also called dimethyl ketone, 2-propanone, and beta-
ketopropane.
• Acetone is used to make plastic, fibers, drugs, and other
chemicals. It is also used to dissolve other substances. It
occurs naturally in plants, trees, volcanic gases, forest
fires, and as a product of the breakdown of body fat.
• It is present in vehicle exhaust, tobacco smoke, and
landfill sites. Industrial processes contribute more
acetone to the environment than natural processes.
25. FORMALDEHYDE
• Molecular Formula CH2O
• Formaldehyde is a colorless, flammable, strong-smelling chemical
that is used in building materials and to produce many household
products. It is used in pressed-wood products, such as particleboard,
plywood, and fiberboard; glues and adhesives; permanent-press
fabrics; paper product coatings; and certain insulation materials.
• commonly used as an industrial fungicide, germicide,
and disinfectant, and as a preservative in mortuaries and medical
laboratories.
