ABSTRACT
1.
We plan to mix the chemicals, Observe the Formation Of Compounds,
and to record their names and formulas. This will guide us in either
discovering new compounds or re-creating old ones. It will also help us
in differentiating the different chemical reactions that will occur when 2
chemicals are mixed.
We plan to use a Pencil, Paper, Ruler, Reaction Surface and a Dropper
to mix the chemicals, record the observations and to differentiate the
chemicals that we’ll use . We’ll also use the chemicals: FeCl3, MgSO4,
CuSO4 and group them as chemical A. And we’ll use the chemicals:
Na2CO3, Na3PO4, NaOH, Na2So4 and group them as Chemicals B. Once
we are done grouping, we will then proceed with the experimentation.
In order to Fully Accomplish the task at hand, We have devised a
procedure and we used the table form the activity sheet as a basis.
1st , we grouped the chemicals, the chemicals without calcium are
marked as group A. Then, the ones with calcium are marked as group B.
2nd , We then mix the chemicals from Group A to Group B. 3rd, We then
distinguish whether the precipitate is Grainy, Milky, Cloudy or
Gelatinous. 4th , We record the Data and we Construct a report using the
recorded data as a result from the experiment.
By accomplishing the experiment, We plan to find the outcome of the
combined chemicals and differentiate it from one another. We’ll also
use the newly formed compounds as a basis whether a chemical
reaction was formed or not.
We therefore conclude that chemical reaction takes place when 2
certain chemicals are mixed together.
This is significant in our lives because everything in this world is made up
of chemicals. And when we further study the Science of Chemistry, we
can therefore improve everything around us.
We recommend the students that they practice their patience and work
together as one because Chemistry is hard stuff.

IF APPLICABLE, demonstrate how
each formula is being used in
computing for the values.
The computations are presented
logically, never setting aside the
rules learned in math classes.
The group chooses the
PROPER form of presenting the
data, whether in tabular form,
graphical form or both.
The design of the tables and
graphs is APPROPRIATE for the
activity (including but not
limited to the interval of
values, determination of
constants, proper placement
of dependent, independent or
manipulated variables, as the
need arises).
All parts of the table or graph
are labeled PROPERLY
(including but not limited to
title, units, x-axis, y-axis,
header, etc.)

When the original procedure
paper CONTAINS Follow-up
Questions given by the
teacher, the lab report
answers all the questions.
10. If the original procedure paper
does NOT contain Follow-up
Questions, the lab report
presents a discussion on the
implications of the data
gathered.
11. Matters that are indirectly
discovered are discussed
including the effects of the
limitations of the activity on
the results.
12. All discussions of data are in
lieu with the objectives of the
activity and are supported by
the data.
13. Information from published
resources are properly cited.

CONCLUSION
We conclude that mixing chemical compounds does create different
chemical reactions. These chemical reactions changes the physical
appearances of the combined chemicals therefore ushering into a new
type of chemical compound. These chemical reactions create new types
of elements/chemicals. And with new elements/chemicals come more
chemical reactions. These reactions change the appearances of the
chemicals therefore creating a compound. The world is full of elements,
and we have barely breached into the surface of chemistry.

14. Questions directly or indirectly
posted by the objectives are
addressed clearly and are
consistent with the gathered
data.
RECOMMENDATION
We recommend Patience, Keen Observation, determination and Full
Cooperation from every member as this subject is hard to accomplish.
And after the students have surpassed the particular subject and have
moved on to the next level, they will have the satisfaction of Fulfilling a
shared goal as a group. The students will need every hands available in
their group in order to fully unleash their potential as one. Unity is the
key to Victory.

15. Weaknesses of the design of
the experiment are discussed.
16. Future students and teachers
are being advised on how to
IMPROVE the activity.
APPLICATION
Chemistry is the building foundation of every man made things in this
world. we can apply this in our lives by using chemistry to further
improve the use of anything in our lives, or to invent new things that
will make life easier for us. And, after we have dug deeper into the
Foundation of Chemistry, we can make a world of Limitless Potential.
