Chemical Reactions
in our Everyday Living

Chua, Himbley F.
9-2 I B03

Objectives:

At the end of this activity, you are
expected to:

1) Identify the chemical reactions
we encounter in our everyday
living;

2) Balance the chemical equation &
determine its type of chemical
reaction; and

3) Determine the importance of
chemical reactions and its
significance in our lives.

Procedure:

1) Look for at least four chemical
reactions that can be found in your
home (like rusting, cooking, baking,
etc.).

2) Type its balanced chemical
equation and classify it according
to its type of chemical reaction.

3) Include as well the importance of
that chemical reaction in our
everyday living. Don’t forget to cite
your reference! Check the example.

Procedure:

4) Take a selfie with each substance, save
it to your device and insert it on each
slide provided below. Please be extra
careful in handling substances, especially
when it’s hot and avoid corrosive
materials! Ask for adult supervision while
doing this activity. NOTE: The picture
should be clear and it must be evident
that your face is shown as evidence that it
was you who did this task.

5) Each item is equivalent to 25 points, a
total of 100 points.

Submission:

1) Once you’re done, convert and save
this ppt to pdf format.

2) While saving your output to your
device, kindly RENAME it as follows
before submission:

Name Initial/s

e.g. PT1_G07_Sy, G.

3) Deadline of submission is on March 7
(Monday) before 4:00 pm.

Name of Chemical Reaction: baking

Balanced Chemical Equation: 2 NaHCO3 → Na2CO3 + CO2 + H2O

Type of Chemical Reaction: decomposition

Example

Importance: Baking has been found to
have therapeutic value which helps to
ease depression and anxiety. Seeing that
one in four people will experience a
mental health problem at some point in
their lives, this wholesome therapy is
good for the whole family. (cited from
Goodnet.org).

Name of Chemical Reaction: Burning stove
Balanced Chemical Equation: CH4 + 2O2 → CO2 + 2H2O
Type of Chemical Reaction: combustion

Chem Rxn #1

Importance: It allows you to quickly heat up
your pans with a large fire, and is much
cheaper than electric cooking. It also
allows you to adjust the heat precisely
yourself (cited from coolblue.nl).

Name of Chemical Reaction: Photosynthesis
Balanced Chemical Equation: 6CO2 + 6H2O → C6H12O6 + 6O2
Type of Chemical Reaction: Combination

Chem Rxn #2

Importance: Photosynthesis is important
to living organisms because it is the
number one source of oxygen in the
atmosphere. Without photosynthesis,
the carbon cycle could not occur,
oxygen-requiring life would not survive
and plants would die.(cited from

britannica.com).

Name of Chemical Reaction: Lighting a match
Balanced Chemical Equation:16KCl3 + 3P4S3 → 16KCl + 9SO2

Type of Chemical Reaction: combustion

Chem Rxn #3

Importance: Friction matches gave
people the unprecedented ability
to light fires quickly and efficiently,
changing domestic arrangements
and reducing the hours spent
trying to light fires using more
primitive means.(cited from

smithsonianmag.com).

Name of Chemical Reaction: Cellular Respiration
Balanced Chemical Equation: C6H12O6 + 6O2 → 6CO2 + 6H2O
Type of Chemical Reaction: decomposition

Chem Rxn #4

Importance: Cellular respiration is
carried out by all living species
including humans, plants, animals,
birds and insects. It is essential for
our daily living, as this metabolic
process helps in producing energy by
the breakdown of glucose and is also
involved in various body
metabolisms.(cited from byjus.com).

Luke 13:20,21

And again He said, “To what shall I compare
the kingdom of God? It is like leaven that a
woman took and hid in three measures of

flour, until it was all leavened.”
