OXYGEN in the periodic table, its chemical formula, its melting point, boiling point and state at room temperature. Oxygen is highly reactive, nonmetal, oxidising agent that readily forms oxides, it is an element. By mass, oxygen is the third-most abundant element after hydrogen and helium. The Atomic Number: 8 Group: The chalcogen group Chemical formula: 02 Melting point: 54.36 k (-218.79 C, -361.82 F) Boiling point: 90.188 k (-182.962 C, -297.332 F) State at room temperature: Gas
2. What do we use oxygen for? Describe two common uses of oxygen in our world, that do not take place within …show more content…
If oxygen goes in iron it turns it rusty because of FE. The oxy- acetylenes torch produces heat by burning acetylene gas (C2H2) in pure oxygen. The torch produces the temperature of 3,000 C (5,000 F) and cuts through steel and other tough alloys. Nearly all organisms requires oxygen - bacteria, plants and animals. A human body can go weeks without water but a human body can’t survive more than a few minutes without oxygen.
3. How does it work within our body? Describe the difference between combustion and respiration, showing a sound understanding of how respiration works and the key differences between combustion and respiration (e.g. rates of reaction, energy required, etc.)
A human body requires to take oxygen to function properly. It takes in oxygen and releases waste gas forming into a carbon dioxide. This two-part process is respiration. There are two types of respiration, anaerobic and aerobic. Aerobic respiration is what we use and animals uses. Aerobic respiration, uses oxygen within the cell to help create energy. When we breath the air enters microscopic air sacs in your lungs which is alveoli. Oxygen passes through the barrier of the alveoli and into the blood stream. Blood carries the oxygen to the cells throughout the body, where it helps to convert nutrients into usable energy. Oxygen is what makes our blood the colour red; blood without oxygen would appear …show more content…
During combustion the heat is supplied on to the sugar which chars and then it gives the flame. The sugar releases energy in the form of heat at a time. From this we can define combustion as the process of burning the sugar to get energy.
The difference between combustion and respiration is that combustion takes place at a high temperature and respiration takes place at a normal temperature. Combustion is a fast process and another hand respiration is slow process. Combustion liberates energy in a single step and another hand respiration liberates energy in several steps. Combustion doesn’t involve enzymes and respiration involves several enzymes.
4. Use APA referencing to cite your references and to write your bibliography (list of references). Use at least 3 resources and do not use Wikipedia as a resource. You can start with Wikipedia, but you cannot use it as a main resource. Wikipedia is not considered a reliable source. Below are two links related to the APA referencing. Read them carefully. A picture below shows how to reference.
