How reaction rate varies with sodium thiosulphate concentration Background information Sodium thiosulphate and hydrochloric acid are both colourless liquids‚ when the two reactants are reacted together they produce sulphur. The sulphur that is produced from the reaction changes the solution to yellow and cloudy‚ this is a precipitation reaction‚ where a two solutions react and a solid forms in the solution‚ the solid is said to precipitate out. Some reactions will occur quickly such as fireworks

However‚ conceptually it will be a little easier because the concepts learned in Chapter 9—namely‚ chemiosmosis and an electron transport system—will play a central role in photosynthesis. 1.

One of the most common conspiracies is that the earth is not a sphere‚ but instead flat. The belief originated in the early times of science when there was little explanation in the world of science. They thought that the earth was flat‚ in their defence‚ what proof did they have that argued otherwise? There had been allegations‚ suggestions‚ and arguments‚ but where was the proof? Finally‚ when science started to evolve‚ the evidence that flat earthers have been missing came forward and proved them

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

samples of size n are selected from each of k populations. It will be assumed that the k populations are independent and normally distributed with means [pic][pic] and common variance [pic]. We wish to derive appropriate methods for testing the hypothesis: [pic] [pic] [pic] at least two of the means are not equal. Table 1 K random samples | |Population | | |

different wavelengths of light and the rate of photosynthesis in spinach leafs. The rate of photosynthesis was measured every five min under light colors of white‚ green‚ red‚ blue and yellow under a light intensity of 2000 lux. The rate of photosynthesis was measured by the spinach disk method in which we replaced the air from the disks with sodium bicarbonate using a vacuum. Under photosynthesis‚ oxygen‚ a product of photosynthesis‚ replaced the bicarbonate solution‚ made the disks less dense and rise
