Stoichiometry deals with the numerical relationships of elements and compounds and the mathematical proportions of reactants and products in chemical transformations
Sound is produced when a matter vibrates. Sounds consists waves and these waves travel as a longitudinal waves. Sound travels fastest in solids because the particles are closer. The speed of sound depends on the temperature of matter. The higher the temperature, the higher the speed of sound is. The properties of sound are reflection and refraction. In reflection, the sound wave turns back when it hits a barrier. A good example of this are echoes and reverberations. On the other hand, refraction is the bending of sound waves.

Chemistry is involved with various and diverse interactions of matter either around us or simply inside the laboratory. These are described using the language of chemistry which consists of symbols, formulas and equations.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

3. Chemical ReactionChemical Reaction
It is a process in which the physical
and chemical properties of the original
substances change as new substances
with different physical and chemical
properties are formed.
Two kinds of substances:
1. The substances present before the
change.
2. The substances formed by the change.
7. 1. Taking and giving off energy1. Taking and giving off energy
• ENDOTHERMIC
– Reactions where energy is absorbed.
– Ex. Cooking of food and Photosynthesis
• EXOTHERMIC
– Reactions that involve the release of
energy.
– Ex. Explosion of firecrackers and burning
of coal
8. 1. Taking and giving off energy1. Taking and giving off energy
9. 2. Color/odor Change2. Color/odor Change
• Ex. Ripening of fruits
3. Evolution of Gas
• The release of gases
• Ex. When you dissolve a tablet of
alkaseltzer in water, bubbles are
produced.
11. 4. Formation of Precipitation4. Formation of Precipitation
• PRECIPITATE is an insoluble solid that
is formed when two liquids react.
• Ex. Combination of vinegar and milk
30. A. COMBINATION/ Synthesis
REACTION
• A reaction when 2 or more reactants
combine to form a single product.
• The general formula for this reaction
is : A + B AB
Example:
N2 +2O2 2 NO2
31. B. DECOMPOSITION
REACTION
• In this reaction, a single reactant
breaks down into simpler ones. (2 or
more products).
• The general formula for this reaction
is: AB A + B C
Example:
2 H2O 2H2 +O2
32. C. SINGLE DISPLACEMENT or
(Replacement) REACTION
• This is when one element replaces another
element from a compound.
• The more active element takes the place of
the less active element in a compound.
• The general formula for this reaction is:
A + BC AC + B
Example:
33. D. DOUBLE DISPLACEMENT REACTION
(Metathesis)
• This is when the positive ions (cations) and
negative ions (anions) of different
compounds switch places, forming two
entirely different compounds.
• The general formula for this reaction is:
AB + CD AD + CB
Example:
34.
35. E. COMBUSTION (Burning)
REACTION
• This is when oxygen combines with a
hydrocarbon to form a water and
carbon dioxide.
• Example of which is the burning of
butane gas.
C4 H 10 + O2 CO2 + H2O
36. F. ACID-BASE REACTION
• This is a special kind of double
displacement reaction that takes
place when an acid and base react
with each other.
• The H+ of the acid reacts with the
OH- of the base forming water. The
other product is salt.
Example of which is:
HCI + NaOH NaCI + H2O
37. Are a burning vehicle and a
puppy undergoing the same
kind of chemical reaction?
What reaction could this
be?
39. COLLISION THEORY
• explains how collision between
reactant molecules may or may not
result in a successful chemical
reaction.
• Effective collisions between
molecules, which result in the
formation of products, only occur
when the following two conditions
are met:
a. the colliding molecules should possess a
minimum kinetic energy, known as activation
40. Svante Arrhenius (1888)
• suggested that particles must possess a
certain minimum amount of kinetic energy
in order to react. The energy diagram is
shown below.
41. ACTIVATION ENERGY
• It is needed to break the bond between
reactant molecules to form new bonds
leading to formation of the products.
• Minimum kinetic energy required for
reaction.
43. B. PARTICLE SIZE OR
SURFACE AREA
• Smaller particles size have bigger
surface area.
• Bigger surface area means bigger
exposed portions of a solid which
are available points of contact
between reactants.
44. C. CATALYST
• A catalyst provides an energy
pathway needed to start a
reaction, therefore increasing
the reaction rate.
• The presence of catalyst
speeds up the rate of reaction.
45. D. CONCENTRATION
It is a measure of the
number of particles in a given
volume.
The higher the concentration,
the faster the rate of reaction.
