Reflection on hands activity and class session SKI 3013

Assalamualaikum and hey everyone.There are many new thing that I learnt during this class.
There are :

1. create crossword and puzzle
2. blogspot
3. wix
4. prezi
5. publisher
6. movie maker
7. flickers
8. chemsketch

As a future teacher,i think that everything i had learnt in this class is important. I can use the items to improve my teaching process to student. For example, i can use my skill in create crossword and puzzle as an exercise to my student. Other than that, i can use my funckychemistry.blogspot.com as the extra reference to my student, therefore they can search and read at home or do as revison. Furthermore, i can create more online resource use the wix.com. Wix give us the attractive and colorful template, so that it can be attracted to student or reader. Next, as a teacher, we can not just depend on textbook and whiteboard to teach student. Thus, through the prezi application, i can create my own note as teaching aids. Teaching aids can help student in development in cognitive. Beside that, i had learnt about chemsketch. I just know about the application. It is so important to me as a future chemistry teacher. I really thankful that i learnt about it because i can easier my job to do any chemical apparatus and chemical formula structure. Not just that, as teacher, our responsibility just not to teach but also have to do a program for our school. Here, i can apply my skill in publisher and movie maker. In class, i had learnt detail about this two application so that it can be my added value as a teacher. 

Here, i want to thank my lecture Dr, Asmayati Bt Yahaya because giving me the opportunity to learnt all this application. SKI3013 class really give me a positive input about these application.

Chemical Formulae

chemical formulae 

A representation of a chemical substance using letters for atom and subscript numbers to show the numbers of each type of atoms that are present in the substance

Compound can be represented by two types: 

1. Empirical formula 

2. Molecular formula

Relationship between the number of moles, number of particles, mass and the volume of gas

Relationship between the number of moles, number of particles, mass and the volume of gas 

That is ☝☝the simple way to remember the formula..Goodluck guys 😉😉

The Mole and the Volume of Gas

The volume occupied by one mole of the gas is called molar volume

One mole of any gas always has the same volume under the same temperature and pressure

The molar volume of any gas is 22.4 dm³ at STP or 24 dm³ at room condition

Relationship between the number of moles and the volume of gas

Example 

How many moles of ammonia gas, NH₃ are present in 600 cm³ of the gas measured at room conditions? [Molar volume: 24 dm³ mol^-1 at room condition]

The number of moles of ammonia gas, NH₃

 600 cm³ /1000 = 0.6 dm³

=       0.6 dm³

    24 dm³ mol^-1

= 0.025 mol

The Mole and the Mass of Substances

The mass of one mole of any substance is called molar mass

Units: g mol^-1

The molar mass of substances are numerically equal to relative mass

Relationship between the number of moles and the mass of a substance

Example

What is the mass 0.1 mol of magnesium? [Relative atomic mass: Mg=24]

Molar mass of Mg = 24 g mol^-1

      Mass of Mg = 0.1 mol × 24 g mol^-1 

                 = 2.4g 

The Mole and Number of Particles

The number of particles in matter is measured in mole

Definition: The amount of substance that contains as many particles as the number of atoms in exactly 12 g of carbon-12 

Symbol of mole : mol

How many atoms are there in 12 g of carbon-12?
= 6.023 x 10²³

• The value of 6.023 x 10²³ is called the Avogadro constant or Avogadro number 
• Avogadro constant, N_A is the number of particles in one mole of a substance

point to note : 

1 mol of any subtances contain 6.023 x 10²³ particles(atom,molecule,unit of ions)

Example

A closed glass bottle contains 0.5 mol of oxygen gas, O_2. How many oxygen molecules, O₂ are there in the bottle?

The number of oxygen molecules, O₂ = 0.5 mol

number of mole x N_A 

= 0.5 mol × 6.02 × 10²³ mol^-1 

= 3.01 × 10²³ molecules 

Concept of Relative Atomic Mass and Relative Molecular Mass

Relative Atomic Mass (R.A.M). RAM is the mass of an atom as it compares to the mass of a carbon atom and has no units. Since it is a ratio, the units cancel out themselves. Carbon was chosen as the standard to which other atoms are measured because it is found in a large number of compounds.

Carbon has a given mass of 12g
The relative molecular mass of each element is listed in the periodic table of elements. For example the RAM of hydrogen, sodium and chlorine is 1, 23 and 35.5 respectively.

Relative Molecular Mass
Molecular compounds contain more than one type of atom, example MgO. So the relatively molecular mass of a compound is the addition of all the atomic masses of each atom in the formula. Some compounds are made up of ions rather than atoms, hence we use the term 

Relative Formula Mass (R.F.M) which incorporates atomic, molecular and ionic compounds

Teaching Philosophy

"Each and Everyday is for Each and Every Student"

I will do my best each day to give students relevant knowledge, the courage to try new things, the curiosity to seek new answer and the ability to be the best they can be. 

Career Development Plan

My long term career development plan definitely to be a teacher. As for now, i still studying my degree, i have to focus to my goal for achieve a good grades. 

I believe a good start will lead to the a good and worthwhile finale.
