CHEMISTRY

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.
