Dialog : Cause And Effect About Chemical Reaction
We can divide the most common linking words and expressions of cause and effect into four group :
1. Coordinating Conjunctions: for (cause), so (effect)
2. Subordinating Conjunctions: because, since, if, whenever, so that, as (cause)
3. Conjunctive Adverbs: therefore, for this reason, as a result, thus, that is why,
consequently (effect)
4. Preposition: because
of, reasons for, consequences of, due to (cause)
Aulia: hello Jelpa!
Jelpa: Aulia, I have
a magic attraction.
Aulia: Really? Show
me!
Jelpa: I cannot do
it here. So instead you guess what would happen if I dipped the paper money into a
glass of alcohol and water, and then I burned it. What is the effect?
Aulia: I know the
answer. As a result is that the paper money are not burned.
Jelpa: wow. That’s
true. Where do you know?
Aulia: I have seen the videos on the internet.
Jelpa: Thus why do you think the paper money does
not burn?
Aulia: alcohol can form a thin liquid on a sheet of
money. Because alcohol is flammable and its density is less than water, the
alcohol remains in the top layer. The money sheet will not burn because alcohol
cannot seeps into the tightly woven money webbing.
Jelpa:
Then if I use plain paper, what is the effect? Whether the paper will not burn?
Aulia: plain paper
cannot be used for this experiment, because alcohol is absorbed much more
quickly on woven loose paper fibers. So the effect is the paper will come
burning.
Jelpa: Well like
that. I wanted to try to do it right away.
Aulia: Be careful in
doing so. Keep your face away from the solution. Alcohol is very dangerous
because it is volatile.
Jelpa: Yes just be
calm down. I will be very careful. After doing so I will be a great magician.
Ha ha.
Aulia: LOL. That is
not a magic attraction. It's just one of those amazing chemical reactions.
Jelpa: okay Aulia.
It’s time to go back to class. See you
later.
Aulia: bye Jelpa. See you!
Except paper money, what we can use to try this experiment?
BalasHapusWe can also use filter paper. Filter paper has a thick enough fiber so that alcohol is not absorbed by filter paper because it is blocked by a layer of water
HapusWhy alcohol is flammable?
BalasHapusThe nature of alcohol when interacting with the air (put in the open) then the alcohol more easily bound to the gas so that alcohol more quickly evaporated, because the faster evaporation that causes alcohol more flammable
HapusWhat will happen if the paper money we dipped into a water without alcohol?
BalasHapusWater is extinguishing fire. If we do the experiment without alcohol, then the paper money will not burn.
HapusChemically the word "burn" or "burning" means more or less "reacting a compound or element with oxygen"
The water of the compound is H2O, two carbon atoms with one oxygen atom. Meaning more or less, water is the result of "combustion" of hydrogen. Burning results can not be burned anymore.
While alcohol, for example ethanol compounds C2H5OH, although it contains one oxygen atom, but still has two carbon atoms and four burning hydrogen atoms.
