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

Carbon Dioxide (CO2) is a colorless gas, which was first discovered in 1577 by Van Helmont who detected it in the products of both fermentation and charcoal burning. CO2 is used in solid, liquid, and gas forms in a variety of industrial processes. These include: beverage carbonation, dry ice, welding and chemicals manufacturing. It is produced by the combustion of all carbonaceous fuels and can be recovered in an abundance of ways. It is widely used today as a by-product of synthetic ammonia production, fermentation, and from flue gases by absorption process. CO2 is also a product of animal metabolism and is important in the life cycles of plants and animals. It is present in the atmosphere only in small quantities (.03% by vol.)

Shelley 1st addresses Victor’s nature. He describes being born a Genevese with a family that is “one of the foremost distinguished of that republic” (Shelley 18). Frankenstein continues to explain his family with adjectives like, “honour,” and “integrity” (18). Shelley’s diction once addressing Victor’s nature describes his family as honorable and prestigious. Being no exception to this prestigious heritage Victor ultimately becomes a victim of his nature. Victor’s greed for power, a bit like the ability that had succeeded him, is simply too exuberant for him to handle. “I had worked…for the sole purpose of infusing life into academic degree inanimate body… I had desired it with ardor that approach exceeded moderation,” Victor states (39). Shelley’s use of powerful words like would like, ardor, and exceeded portray the thought of this overwhelming would like for power in Victor’s nature, and foreshadows Victor’s final downfall.
Stated by The Columbia Encyclopedia, 6th Ed. It is said that “Charcoal is a substance obtained by partial burning or carbonization (destructive distillation) of organic material, a charcoal is largely pure carbon.” In addition, The Columbia Encyclopedia said that the entry of air during the carbonization process is controlled so that the organic material does not turn to ash, as in a conventional fire, but decomposes to form charcoal.

...vel, passing one story onto his sister and the reader, though he does serve a purpose as the character who sees wrong in what he is doing, contrasting with the other two protagonists. Walton is also the neutral approach towards the whole tale, providing the story with a ‘filter’ to remove Victor’s opinions and perspectives that are invalid and unimportant to the tale. Walton is also used as a parallel to the monster and Victor but is often perceived as the ‘shadow’ of Victor. Shelley includes many of her personal life within the novel as is evident in the monster’s upbringing, her childhood contrasts greatly with that of Victor’s. Though I don’t believe he is included just as a mechanical narrative device, I believe that he is used to represent the reader. In a way that states that what he does at the end of the novel is what every budding scientist should do: stop.

This is because only a small part of the population, particularly in developing countries, have access to water of acceptable quality. It is estimated that in some countries only 20% of the rural population has water of satisfactory quality. Based on these statistics, it is clear the urgent need for awareness about caring for water use. Almost without realizing it, we are seriously jeopardizing this essential resource, not for us but for our children's children and their generations, aware that in other parts o...
This novel supports Shelley’s thought about society’s attitude toward female authors and how they were considered inferior. She demonstrates how female authors are shunned by society, just like the creature is shunned. The creature embodies the feminist ideals Shelley weaves into the novel and highlights societies unfair treatment of women. In some ways Shelley identifies with Victor because both of their creations were not what they expected them to be and were worried about the criticism they would receive for it. They both hid their creations for a while, Shelley did not immediately claim the novel and Frankenstein did not claim his experiment

Having clean water to drink means that water must have microbial, chemical and physical characteristics that meet WHO guidelines or national standards on drinking water quality. Around 780 million people in the world don’t have access to clean drinking water (Millions Lack Safe Water). More than 3.4 million people die each year from water, sanitation, and hygiene-related causes. Nearly all deaths, 99 percent, occur in developing countries. Around the world, diseases in unclean water kill about 1,400 children every day (Clean Drinking Water). There are many organizations that raise money in order to help develop ways or create ways for people to obtain clean drinking water. However, many people are unaware that this is even a problem in other countries because we take clean water for granted.
