CHEMISTRY



CHEMISTRY is the

study of matter – its

composition, structureproperties,

transformation from



one form to another

and the energy thaaccompanies its

transformation.



Branches of Chemistry

Organic Chemistry: I

deals with substances tha

contain the elemen

carbon.



Inorganic Chemistry: I

deals with all elementsand compounds other

than organic

compounds.



Analytical Chemistry: It i

concerned with theidentification o

substances through asystematic determination

of their composition.



Biochemistry: It is

concerned with the

chemistry of lifeprocesses and living

organism.



Physical Chemistry: I

deals with theapplication of physica

laws to chemical changeand chemical systems.



The Philippine

coconut industry

provides livelihoodto 1/3 the country’s

population. Sixty –



eight out of 79

provinces are

coconut areasCoconut is among

the top 10-expor



produce of our and

we have 59% share

in world coconutexports.



1. What is the

composition of eachpart of the coconut –

fruit, leaves, trunk and

roots?



2. What are the boiling

point and melting poinof coconut oil?

3. What is the bes

processing procedure



and conditions that wil

yield high quality andquantity of oil?

4. Why does oil become

rancid?



5. What changes take

place in copra duringstorage?

6. How much energy isderived from the



burning of coconut oil

shell and husk?7. What are the uses o

many chemicals derivedfrom the different part

of the coconut tree?



Which branch o

chemistry might work inthe following situations?

a. determining mercurylevel in fish.



b. improving the fue

characteristics ogasoline.

c. developing new bloodclotting agents.



d. determining the

properties of sulfur &oxygen.

e. nutritional studies oindigenous food and

legumes.



f. calculating the energy

needed to break a singlebond.

g. understanding themechanisms of enzymes



Make a collage out o

the cut – out pictures

from newspaperlabels of commercia

products or magazine



by pasting them on

Oslo paper to depic

the Impact oChemistry on Society.

Activity 1



Chemistry In Our Midst

I. Objective: Todetermine the role o

chemistry to society.



II. Materials: Cut ou

pictures of chemicaproducts, pair o

scissors, paste, osloIII. Observation:



Chemical

Products

Area of

HumanNeeds

Uses



Guide Questions: From

the collage you made



name the chemica

products. Give their useand the area of human

needs in which they areused.



IV.Generalization:

____________________________________________________________________________.

V. Application: Describe the

role/s played by chemistry

on each area of human

needs.



The principles o

chemistry are needed tounderstand the nature o

matter so that we will beable to deal with it and

use it for the



improvement of life and

the environment.Knowledge of the

properties, structure ofand changes in matte

guides in designing new



compounds or copying

known structuresdeveloping new processe

or chemical products andimproving on those change

that occur naturally.



Chemistry serves society’

needs. Through chemistrymany new materials hav

been developed andproduced for our use and

enjoyment.



Most of the product

around us depend on thechemical industry.

The world around us imade of chemicals. Ou

food, clothing, the



building in which we live

are all made of chemicals
