Hello Good day and Welcome to our
general chemistry one
subject so let us continue our
discussion about the chemical formula of
common chemical
substances So ano ba iyung mga chemical
formula at saka Ano itong mga common
chemical substances so let us have here
an example we have c o and 2 so we have
the element carbon combined with oxygen
Tapos merong number two dito So what
does it
mean so let us have What is a chemical
so a chemical is a compound or
substance Syempre chemical formula
hinahanap natin combine natin sa formula
Ano ba muna yung formula formula is the
symbolic expression so kapag pinagsama
natin we can describe the chemical
formula as a symbolic expression of a
compound or substance so ito yung
example natin pinagsama natin yung
dalawang elements ' ba substance yan
isang Carbon isang oxygen pinagsama
natin that is our
expression of a compound naging compound
na yung ating dalawang elements ito
ngayon ang kanyang chemical formula and
we call this the carbon
dioxide it is also called the short hand
of expressing the types and the number
of atoms so for example dito sa ating
Carbon kapag wala kayong nakikitang
katabi niya na subscript that means
merong one na Carbon
atom kapag meron naman dito sa two meron
dito sa Oxygen ibig sabihin ang number
of atoms niya ay 2 two oxygen Pero kapag
Carbon lang kahit wala kayong nakikita
dito na number Ibig sabihin po niyan
merong one atom
Okay so Oo na ang subscript na sinasabi
natin chemical symbol kasi abbreviation
that represents the name of an element
so isang symbol natin ito ang Carbon
Tapos isang o oxygen so itong dalawa
these are chemical symbols chemical
symbol ang ng Carbon is capital letter c
chemical symbol ng ating Oxygen is
capital letter O then yung maliit na
number Ito yung tinatawag na subsp the
small number written at the lower right
corner so mas maliit siya hindi siya
kasing pantay or kasing taas ng cont
size ng ating carbon dioxide
Okay so common name kasi ang topic natin
is yung chemical formula of common
household elements common name natin we
have the table salt or yan yyung alam
natin na Asin chemical compounds niya we
have the sodium
chloride chemical formula nacl so na yun
yyung sodium CL is chlorine ano Iyung
uses we have the condiment and food
preservative so ginagamit yung asina na
sa condiment sawsawan natin Ganyan
panghalo din sa pagkain or pang preserve
next is the baking soda That is called
also called the sodium bicarbonate we
have sodium na itong H is hydrogen meron
tayo ditong Carbon and meron tayong
oxygen Pero pagdating dito sa Oxygen
Tatlo ang kanyang number of atoms baking
soda is an ingredient in baking next we
have the lie or the caustic
soda chemical niya chemical compound
sodium
hydroxide na sodium pa rin o meron
tayong oxygen meron din yang hydrogen so
tig-iisa lang sila ng atoms So parang
katulad dito
na dahil meron ditong isang ah um
invisible na number ibig sabihin may one
atom ang ating CL ay wala ring number
dito pero may invisible diyan na 1 one
atom so balik tayo sa caustic soda
manufacture of paper soap and detergents
next we have Dem moriatic acid
hydrochloric acid Iyung tawag diyan
capital h for the hydrogen and then
CL for chlorine so hydrochloric acid
ginagamit din natin for cleaning ' ba
next we have the ammonia or ammonium
hydroxide and for nitrogen and then we
have three atoms of hydrogen isa lang
yung nitrogen dito pagdating dito sa
hydrogen meron tayong tatlo Ayan
nakikita natin yung subsp and yung
ammonia ginagamit siya as fertilizer at
saka
explosives next we have the Consumer
products so dahil alam na natin yung mga
um chemical compounds Pati yung mga
chemical formula nila ' ba
so Punta na tayo sa Consumer products so
analyze muna natin to analyze the
picture Then answer the guide questions
picture is a soap which problem is being
addressed by the invention of the bat
soap tapos What substances are needed to
make bat soap so Bakit napunta sa bat
soap sagutin muna natin yung guide
questions ba naimbento yung bat soup
kasi kailangan natin ng panlinis ng
ating katawan then what substances
kanina meron tayong sinabi sa chemical
compound so let us answer this table
fill out this table Consumer product
natin is bat soap some chemical
components we have the use label of
safeness at saka cost so we have common
components glycerine So ilang number of
atoms yung ating Carbon ilang atoms yung
hydrogen ilang atoms yung ating Oy
makikita natin sa subsp yung Carbon
meron siyang three atoms yung hydrogen
meron siyang e atoms yung oxygen meron
siyang three atoms another chemical
component is the sodium hydroxide or the
naoh so na para sa Sodium tapos meron
tayong o para oxygen and h para hydrogen
another chemical Compound is the
Titanium
dioxide ti for the Titanium tapos
dioxide o so isa lang yung sa Titanium
pero dalawa sa Oxygen kaya d means two
dioxide next we have the triclosan
c c 12 atoms Carbon yan hydrogen we have
7even atoms chlorine 13 atoms oxygen 2
atoms so Syempre alam natin yung bat
soup ano yung use niyan Ayan to cure
skin infection and Syempre improve yung
ating personal hygiene Kaya kailangan
maligo tayo lagi safeness yan generally
safe basta External use yung iba nga
lang allergic kasi Depende nga sa UM
katawan din tsaka Depende sa sabon pero
pag external lang naman generally
karamihan talaga ng soap natin ay safe
cost so Syempre affordable kasi yung mga
non-branded
pero yung iba naman ay medyo mahal din
so ingredients of bat soup Para saan
yung glycerine na sinabi natin kanina
ito yyung
moisturizer para naman pag Nagsabon tayo
hindi naman magdry yung ating mga skin
main ingredient ng sabon natin is sodium
hydroxide Oo naman Titanium dioxide
dinadagdag para ang atin pong sabon ayy
maging opaque ibig sabihin hindi
transparent yung sabon natin para solid
Yung kanyang pagiging color hindi
tatagos yung light doon sa sabon kaya
yung pag nakita niyo yung solid yung
color ng isang sabon merong mga color
green color white um color blue yung iba
color pink o kaya orange next we have
the triclosan Ito naman yung
antibacterial Regent so kailangan talaga
to sa ating bat soap ito yung mga um
purpose din or uses ng ating different
chemical compounds so vocabulary word
Syempre sabi natin kanina alam na natin
yung mga chemical compounds pero pati
yung sa Consumer products dahil alam na
natin na binebenta yung mga bath soups
na ganyan and other products ito na
ngayon yung ating idadagdag sa
vocabulary words ano yung cause Syempre
yan yung presyo ng ating product yun
yung binibili natin for example yung
yung sabon nga na product natin Magkano
yun Consumer product ito na yung final
good bibilhin natin para sa personal na
gamit o kaya ayan both for consumption
by the average Consumer so ito na yung
pinaka product
na So how about the science technology
and society Syempre yung mga consumer
products nagagawa po yan dahil sa UM
relationship ng ating science technology
and society also called as s t and s so
Iyung knowledge natin sa Science
ginagamit iyan para makapag gawa or
makapag-produce ng ating mga Consumer
products yun na yung technology natin
para saan ba ' ba kailangan ma-solve
yung mga problems ng ating community yun
na yung society So yun ung kinalaman ng
ating science sa technology at sa
society So for example yung bat soap isa
siyang product ng a so yun yung
technology ' ba Consumer product yan um
Sins niya kasi yung mga problem ng ating
society na skin infection and poor
hygiene So that's all for our lesson
today Um thank you for watching and
listening
