Chemistry is the science that studies matter
Students of chemistry study the living and non-living things’ behavior
Everything around us consists of matter
The houses, soaps, sea breeze, and even the flowers.
In our chem. class, we studied first about significant figures
All non-zero digits are considered significant figures
Leading, captive, and trailing zero
You must identify so that the significant figures will show.
We also studied about scientific notation
The lesson we had in Math class was shown
Ma’am Tingatinga explained the rules in addition and subtraction
And also the rules in multiplication and division.
Conversion factors are also part of our lesson
This made us to change our avocation
One meter is equal to one hundred centimeters
While one kilometer is equal to one thousand meters.
Another lesson is about temperature conversions
It doesn’t have something to do with prepositions
°C to °F, °F to °C, °C to Kelvin
Kelvin to °C, Kelvin to °F or °F to Kelvin.
Mole is called the chemist’s dozen
You multiply 6.02 to the given exponent
The given figure is called the Avogrado’s No.
You use the conversion rules so you can get the measure.
Properties of matter are identified as intrinsic or extrinsic
Dependent is extensive, while independent is intensive
Systems having the same appearance and properties are homogeneous,
While systems having different faces are heterogeneous.
Radioactivity emits radiation
The change from one element to another is transmutation
I have known new words about nuclear reaction
Alpha, beta gamma, positron, and neutron.
I have known things about periodic table notation
Group no., period no., electronic configuration
The group no. is the vertical arrangement
While the period no. is the horizontal arrangement.
Mendeleev discovered the first periodic table of elements
Some examples are Boron, Carbon, Nitrogen, and Oxygen,
Rubidium, Strontium, Yttrium, Zirconium,
Rhenium, Osmium, Iridium, and Platinum.
Chemistry has big contributions to society
Examples are polymers that are named with the prefix “poly”
To all of the community’s problems and questions
I think Chemistry is the solution.
