CAUSE AND EFFECT IN CHEMICAL REACTIONS
THE DIALOGUE ABOUT " CAUSE AND EFFECT "
RINI : " Hello mega, long time no see, how are you ?"
MEGA : " Hello rini, i'am fine, and you ?"
RINI :" I'am fine too thanks mega, hmmm mega what are you doing at here?"
MEGA : " hmm, i'am just looking the iron Rin, and what actually happens on this iron? why the color change can happen? can you explain about that rini? cause you know iam so corious about that!
RINI :" hmm, it happen if the iron reacts with the oxygen containing water, so that is can make the iron becomes rusty and it's cause the color change of iron.
MEGA : " ooooo, i see so that its causes of being a rusty iron, right rin?"
RINI :" oooo, thats right mega!
MEGA :" ooohh ya rini, i want to ask you about ethanol!"
RINI :"Yes, please mega, what do you want to ask with me?
MEGA:" rini, why if i dip the filter paper in a mixture of ethanol to which ha been added water, and the filter paper cant burn ? can you expalin about it rini ?!"
RINI : " Yes, mega you know what the filter paper cant burn? thats because the filter paper in dip a mixture contains the water, so thats make the filter paper cant burn. why in lit it? because the fire butn ethanol is on filter paper while water it didn't come on fire.
MEGA :" ooo so like that makes the filter paper cant burn, right rini?"
RINI :" Yes, thats right mega!"
MEGA : " Okay rini, now iam understand about it, thank for the time rini, and see you next time, nice to meet you rini!"
RINI:" Okay mega, your welcome, nice to meet you too, see you mega!

What is the characteristic of Etanol?
BalasHapusokay, thanks hana, for the first we must must know what is ethanol, Ethanol, also called alcohol, ethyl alcohol, and drinking alcohol, is the principal type of alcohol found in alcoholic beverages. It is a volatile, flammable, colorless liquid with a slight characteristic odor. Its chemical formula is C
Hapus2H
6O, which can be written also as CH
3-CH
2-OH or C
2H
5-OH (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH.
Characteristics of Ethanol (A Polar Solvent)
Emergency responders are generally not going to encounter pure
ethanol unless they respond to an event at an ethanol production
facility. Ethanol for use in motor fuel blends will generally be
denatured with up to 5 percent gasoline or a similar hydrocarbon (E-95)
for any style of transport. Nevertheless, the following discussion of the
characteristics of ethanol will be based on pure rather than denatured
product, for in actuality the denaturant will have minimal effects on
product characteristics.
Ethanol is a renewable fuel source that is produced by fermentation and
distillation process. The most common source of ethanol in the United
States in 2008 is corn. However, it can be produced from other products
such as sugar cane, saw grass, and other natural products that will be
conducive to the fermentation/distillation process.
Ethanol is a polar solvent that is water-soluble and has a 55°F flash
point. Ethanol has a vapor density of 1.59, which indicates that it is
heavier than air. Consequently, ethanol vapors do not rise, similar to
vapors from gasoline which seek lower altitudes. Ethanol’s specific
gravity is 0.79, which indicates it is lighter than water but since it is
water-soluble it will thoroughly mix with water. Ethanol has an
auto-ignition temperature of 793°F and a boiling point of 173°F.
Ethanol is less toxic than gasoline or methanol. Carcinogenic
compounds are not present in pure ethanol; however, because gasoline
is used in the blend, E-85 is considered potentially carcinogenic.
Like gasoline, ethanol’s greatest hazard as a motor fuel component is its flammability. It has a wider flammable range than gasoline (LEL is
3.3 percent and UEL is 19 percent). In a pure form, ethanol does not
produce visible smoke and has a hard-to-see blue flame. In a denatured
form there is little to no smoke, but a slight orange flame may be
visible. Interestingly, ethanol and some ethanol blends can conduct
electricity while gasoline does not and is considered an electrical
insulator.
Instructor Note:
Ask participants the difference between renewable and non-renewable resources.
Answer:
• A non-renewable resource is a natural resource that cannot be remade, regrown, or regenerated.
• A renewable resource is one that can be replenished.
Ask participants for examples of non-renewable and renewable resources.
Answer:
• Non-renewable resources would be fossil fuels such as coal, petroleum, and natural gas.
• Renewable resources would be things like water, oxygen, timber, fruits, and vegetables
The most striking difference between these two fuels is that unlike
gasoline, ethanol mixes easily with water. While it is possible to dilute
ethanol to a condition where it no longer supports combustion, this is
not practical in the field as it requires copious amounts of water. Even
at 5 parts water to 1 part ethanol, it will still burn.
if i use the paper of book, what happened ? is the paper burned or not ? give me explain about that !
BalasHapusokay vicky, thanks for the comment and visited my blog i think if we change the filter paper to normal paper the effect will be same like before, when the normal or book paper contains water and we use ethanol for the alcohol, the paper was not burn when we try to burn it with fire same like that paper cant burn, thanks fiki
HapusWhat is the function of ethanol?
BalasHapusokayy uul thanks for the comment the function of ethanol is Ethanol is made out of corn (maize) and when mixed with petroleum (gas) can be a greener alternative to regular gas. Usually used in hybrid cars. in this specimen the function of ethanol is make a filter paper is burn, i think thats ul thanks uull
HapusHow to get rid of iron rods?
BalasHapusokay thanks for the comment mel Get rid of rust stains
HapusRust doesn't just affect the metal it's formed from. It can stain clothing, brick work, and just about anything else it touches.
If you find rust stains on clothing, try some lemon juice. Rub the lemon juice into the affected area, being careful not to spread the stain any further. Rinse the lemon juice off with water, then wash the clothing as as normal. If the fabric is thick, and the rust stain particularly bad, add some salt to the lemon juice.
To remove rust stains from a wall, drive or patio, use a stiff wire brush and a hose. Wet the stain with the hose and then brush the stain firmly. If the stain is particularly stubborn, try using a cleaning product which contains oxalic acid, such as Bar Keeper's Friend Stain Remover.
why paper did not burned when pour to ethanol and burned
BalasHapusokay aldi thanks for the comment, why paper cant burn, that is because the filter paper contais the water, and the fire on from the ethanol, the water make a filter paper cant butn, i think thats enough aldi, thanksss
HapusHi rinii, could you give me other causes and effects in daily life related to chemical reactions?
BalasHapusokay rahmi thanks for thecomment, the example of cause and effect in dailly life is Cooking air, while cooking air, the air will cook or boil while removing air vapor, here air vapor serves as the effect of the heating of air
