Producing Carbon Dioxide from a Metal Carbonate
Metal Carbonate Metal Oxide + Carbon Dioxide
Thermal decomposition ‘is when a substance breaks down into simpler
substances when heated, often with the help of a catalyst. It’s
different from a reaction because there’s only one substance to start
with’. I came across this information in the EDEXCEL Modular Science
revision guidebook 1. Thermal decomposition is the breakdown of a
substance using thermal energy, this is not a reaction.
Preliminary experiment
Limewater and copper carbonate were used to see if a metal carbonate
beaks down to produce carbon dioxide.
This is what the experiment looked like:
The equation for this:
CaCo3(s) CuO(s) + Co2 (g)
This experiment was to see if carbon dioxide was produced from a metal
carbonate. In this case copper carbonate was used. Two test tubes were
linked together by a rubber tube, which had a glass pipe coming out of
the cork that prevented any of the carbon dioxide or any other gas
from escaping. As you can see from the diagram in one tube there was
limewater that was to test for the carbon dioxide, and in the other
was copper carbonate. If there were carbon dioxide present, the
limewater would turn cloudy (white in colour). When I was observing
what happened I could see that there was carbon dioxide present
because the limewater turned cloudy.
Secondary Experiment
This experiment was to compare the rates of decomposition of several
metal carbonates. Several metal carbonates were placed in a test tube
and linked to a syringe that measured the amount of carbon dioxide gas
when the metal carbonates were heated.
This experiment is to see how fast metal carbonates will break down to
produce carbon dioxide.
The reason they break don’t break down at the same time is because
more reactive ones don’t want to break up. So the longer it holds onto
its carbonate the more reactive the metal is.
In this experiment there are a few factors that can affect the results
of the experiment. These factors can make the results of the
experiment be incorrect. The factors that can affect the experiment
are:
1 Water
2 Amounts of powder
3 Distance the flame is away from the metal carbonate
Water can affect the results because it can get into the powder, which
can speed up a reaction.
If different amounts of the substance are used, then the results can
be affected because the more amount of powder there is, the more
carbon dioxide will be produced.
Plan
In this experiment I plan to use 1/500 of a mole. This is because if
anything greater is used then the amount is too great and the results
this is the best volume to use as it is about ¾ of a test tube full,
We finally took 1ml of the 0.01% solution from test tube using the glucose pipette and adding it to test tube 4, we then used the H2O pipette and added 9ml of H2O to test tube 4 creating 10ml of 0.001% solution.
Each subsequent trial will use one gram more. 2.Put baking soda into reaction vessel. 3.Measure 40 mL vinegar. 4.Completely fill 1000 mL graduated cylinder with water.
3.) Divide your 30g of white substance into the 4 test tubes evenly. You should put 7.5g into each test tube along with the water.

The psychoanalytic perspective tells us that behavior is determined by one’s past experiences and that these experiences have been locked in the unconscious mind and the character is unaware of them. This perspective is also based strongly on Freud’s studies of the mind. The major experience in Victor’s life was the death of his mother. Victor was very close to his mother and she died before he left to go to college in Ingolstadt. Shelley wanted to make a point by placing Victor’s mother’s death before he left for the university, to act as his separation from her and to show that he was unable to continue life in the way a usual human being could. Victor’s studies at Ingolstadt strictly went against his father’s words and could be seen as Shelley placing a type of Oedipus complex in his career pursuits. This led Victor to creating the monster to have someone he could be with. After working for 2 years, Victor finished his creation and said, “Now that I had finished, the beauty of the dream vanished, and breathless horror and disgust filled my heart” (...
...aused him to have a low tolerance to nurture. Shelley is conveying that trying is worth it; at the beginning of the story, Victor was passionate about his science and worked hard to complete his quest for knowledge with success in attaining the skills needed to create life, but once something went wrong (his failure in creating the Creature) he became disheartened and through his lack of perseverance, things only got worse. By leaving the Creature almost immediately, Victor demonstrates his low nurture. Conversely, if he would have had a high nurture then he would have stuck around and tried to get to know the Creature. Victor’s arrogance is another factor that contributes to his lack of nurture. By not visiting his family while he is away at school he is ruining his opportune relationship with them by portraying a lack of love and only turning to them when in need.
In the beginning, Shelley uses foreshadowing to allude to Victor’s ultimate demise due to his unrestricted curiosity. In describing his own childhood, Victor keeps referring to his imminent doom: his interest in science which he describes as “the fatal impulse that led to [his] ruin” (Shelley, 39). Victor’s recollection, although filled with joy from his happier past, emphasizes the tragedies in order to forebode a future disaster. Additionally, his stress on fate and destiny remind the reader of the inevitable outcome; however, it also alludes to Victor’s attempt to challenge his responsibility of his own actions. When he finally decides to study chemistry, in retrospect, Victor blames his choice that day as the day that “decided [his] future destiny” (Shelley, 48). He blames destiny for his current misery, not his own ac...

Carbon Dioxide is a colorless, odorless gas that occurs in small quantities in the earth's atmosphere naturally. The earth's ocean, soil, plants and animals release CO2. The formula of Carbon Dioxide is CO2. The CO2 molecule contains 2 oxygen atoms that each share 2 electrons with a carbon atom to form 2 carbon - oxygen double bonds. The atoms are arranged as so (OHT). This is called a 'linear molecule'.
