EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

Cellular respiration and photosynthesis are fascinating‚ complicated‚ and important processes that are essential to life. Cellular respiration exists in animal and plants‚ whereas photosynthesis only exists in plants due to the chloroplast organelle. Cellular respiration starts with glucose‚ and oxygen and the photosynthesis process on the other hand starts off with the absorption of photons of light from the sun.While the end products of cellular respiration are carbon dioxide‚ water‚ and ATP‚ the

Aim To work out how light intensity can affect the rate of photosynthesis. Hypothesis I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Although the closer the light source is‚ the more photosynthesis‚ the light source could also kill or damage the Elodea (type of pondweed) because it could become too hot and denature its cells. But because

The effect of light quantity on photosynthesis of green land plants Introduction Photosynthesis is the process of converting light energy into chemical energy (Hoober 1984). Pigments within chloroplasts‚ primarily chlorophyll‚ absorb the incoming solar energy which excites their electrons (Hoober 1984). These pigments exist in photosystems in the thylakoid membrane of the chloroplast (Ladiges et al.2010). As the electrons return to ground level‚ they are captured by the electron acceptor in the

Photosynthesis simply means the conversion of light energy into chemical energy by living organisms. In photosynthesis‚ the raw materials are water and carbon dioxide. Energy is taken from sunlight and the end products give out glucose and oxygen. It is the most important‚ naturally occurring process

Plants can make their own food through photosynthesis and then break it down for usable energy through the process of cellular respiration. Analyze and explain how your life might be different if you could make your own food through photosynthesis. First of all if we were to be able to make our own food trough photosynthesis‚ we should have chlorophyll‚ which is the important pigment in absorbing sunlight. As an effect we will all be green in color. This may be good as there will be only one race

The carbon cycle is a biogeochemical cycle that displays how carbon circulates throughout the environment. Many components affect this process such as photosynthesis and cellular respiration. Photosynthesis uses the carbon dioxide that is in the atmosphere to transform it into sugar and oxygen; cellular respiration puts carbon dioxide in the air. Both of these processes were studied during the experiment. In the experiment‚ the tube with both the elodea and the snail had the same level of carbon

AFFECTING THE RATE OF PHOTOSYNTHESIS. Introduction Photosynthesis is a chemical reaction which takes place inside the green plants (plants with chlorophyll‚ a pigment found in chloroplasts which causes the colour of the plants and it is the main photosynthetic pigment) and light energy is converted into chemical energy. Carbon dioxide‚ water and sunlight is transformed into sugar an oxygen‚ which later will be used as energy for the plant. The chemical equation of photosynthesis is: Photosynthesis

There are many variables that could affect the rate of photosynthesis and the net consumption of carbon dioxide. In this experiment‚ the effects of how the intensity of light energy affected photosynthesis were observed. Two pieces of elodea was placed into separate beakers and one of the beakers was placed under a bulb of lower intensity and the other beaker being placed under a higher intensity bulb. The results showed that the beaker under the higher intensity light energy had a higher consumption

Chlorine in Photosynthesis Experiment Abstract Photosynthesis the means by which green plants and different types of organisms use light from the sun to synthesize foods from CO2 and H2O. Chlorine is a chemical element usually in the form of a yellow-green gas and is a strong oxidizing agent. Elodea is a type of aquatic plant also known as waterweed that is native to North America. In the experiment that took place‚ the effect of chlorine in the presence of photosynthesis reactions were studied
