Dead. This is only my 2nd post in this blog and Ms Jee is starting notice that lazy people excluding me ( too busy ) are not updating their chemistry blog. Ok here I go, I gonna summarise what I learnd during my 2 weeks of chemistry lesson which is gonna be short; due to the fact that I'm absence for most of Ms Jee's lesson ( too sick ). Ok. So far i covered most of my doubt in the chapter ( Atoms, Molecules and Stoichiometry( <- how the fish do you pronounce this word)).

What Kensei covered.

-Defination of terms <br>

(1). Relative Isotopic Mass. Defined as mass of one atom of an isotope compared to 1/12 the mass of carbon -12.

(2). Relative Atomic Mass. Defined as mass of one atome of an element compared to 1/12 the mass of carbon -12.

(3). Abundance. Is the percentage of isotpe found in the naturally occuring element.

(4). Relative Molecular Mass. Is the sum of the relative atomic masses of all atoms in one molecule in a covalent compound.

(5). Relative Formula Mass. Is the relative molecular mass of an ionic and giant molecular compound.

(6). Avogadro's constant, ( 6.02 x 10 to the power of 23 ). Is equal to one mole of any substance's amount of particles.

(7) Crap, for now that's all I learned.

Sorry for not updating for a long time, I live in Hougang ( not to make it into an excuse). I take around 2 hours to go forth and back to school. Tiring but I'll try my best to update this blog as soon I learn something ( which is really hard ) or if I'm free and has no massive amount of homework.

We learned Titration during one of our lessons this week. We are expected to be very ( damn ) accurate because most of our results are wrong ( duh ) or we just screwed up last minute due to the time constrain or, the apparatus is not rinsed well and its contaminated.

What Kensei learned.

(1). No consuming of any edible substances in the lab, not even the chemicals. ( Even if they're tempting )

(2). Accuracy. Consistantly record your observation even if its the slightlest reading.

(3). The Litmus test. ( Which i flunged hard )

(4). How expensive the apparatus are and to handle them with care. ( $ is involved, CAREFUL )
