Research Question/Aim To understand the change in mass after burning magnesium and to also determine the chemical formula of magnesium oxide Hypothesis Burning the magnesium will result in an increase in mass because the magnesium will react with oxygen in the air to make magnesium oxide Variables Independent- Initial mass of magnesium (Mg) Dependent- Mass of the burnt magnesium (MgO) Controlled: Intensity of flame Apparatus used (same crucible‚ Bunsen burner‚ tongs‚ electric balance) Duration

Glucose + Oxygen → Carbon Dioxide + Water + Energy (C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP) This type of respiration is called aerobic respiration which means respiration with oxygen. Mitochondria carry out respiration in the cells. This is why muscles have so many mitochondria as they need more energy in order to function. Respiration comes in two forms – anaerobic and aerobic. Anaerobic respiration refers to respiration without oxygen. A common example of this is swimming as there is no oxygen in water

surroundings. The amount of caloric intake required combined with how much oxygen they use during their main activities could tell us a lot about what it takes to live in such an unyielding and unforgiving environment. But by learning how much energy they use and how they use it we could learn a lot about We measure how much energy it takes an otter to do something by measuring the oxygen consumption during surface behaviors‚ and the oxygen consumption after an otter returns from a dive. This is done using

manufacture ATP by phosphorylating ADP. Many prokaryotes and virtually all Eukaryotes phosphorylate ADP either through fermentation (anaerobic) or respiration (aerobic). Both of these processes involve oxidation of foodstuffs‚ yet only the latter requires oxygen. Cellular respiration is a very complex process that consists of many steps that take place inside the cell‚ in an organelle called a mitochondrion. Mitochondria are responsible for converting digested nutrients into the energy-yielding molecule

dissolved oxygen content of pyrite pulp after various aeration times of the pulp. Initially‚ the pulp was purged with air for 3 minutes and the dissolved oxygen content was then measured with time. They observed that the dissolved oxygen concentration of the pulp reduced from 5.5 to 0.06 mg/dm3 during 5 minutes. This showed that the oxygen dissolved in the pulp was nearly completely consumed by pyrite. However with increasing aeration time‚ it was observed that the residual dissolved oxygen content

interaction between the two layers. The reason why there is a difference in the density of the same body of water‚ is due to the dissolved oxygen (DO) intake of water. With cooler water having a greater capacity to hold oxygen compared to warmer bodies of water. Usually this problem is fixed with the combination of photosynthesis from plants that produces oxygen‚ and wave to wind action that help breaks down thermal stratification and allow for water on the surface of the pond to be oxygenated by

C1 Revision Notes Atmosphere is a mixture of gases that surrounds the Earth. The three main chemical components present in air are Nitrogen‚ Oxygen and Carbon Dioxide. Trace amounts means only a very tiny concentration of gas is present. An element is made up of 1 type of atom. A compound is made up of 2 or more types of atom that are chemically bonded. A mixture also contains more than 2 or more type of atoms but they cannot be chemically bonded. A pollutant is a waste matter that contaminates

Whooshhh! Space exploration has many meanings to me. It means improved life on Planet Earth. It can help with saving energy‚ using our phones‚ and even predicting the weather! There are lots of meanings to space exploration and they all help us get through the day. Get Ready for lift off! We can rely on the weather reports updated on an hourly basis. The accurate weather forecast is possible only because of the satellites in the space. It’s easy to predict natural calamities such as floods‚ storms

Deforestation Plants give us oxygen which is the most important thing for our survival. They undergo a process of photosynthesis in which they give out oxygen and take carbon dioxide. Plants consume the air‚ sunlight and the carbon dioxide we breathe out to make food and oxygen. So if trees are cut‚ plants will not produce oxygen and the concentration of carbon dioxide will increase. Increase of carbon dioxide in the air is harmful for human beings and also disturbs the water cycle and hence the

Table 5.2. 6. The glass beads cannot produce gas‚ so it served as a control‚ due to no change in the volume of gas. 7. Germinating seeds have an increased metabolic rate‚ which in turn needs more oxygen. The non-germinating peas are smaller and barely alive‚ so they only need a little bit of oxygen to live. 8. See Graph 5.2. I think the graph will rise to a max peak of 40 C‚ where it’ll consume the most‚ then begin to decline as the heat increases past 50 C. 9. It was used to absorb excess CO2
