Concentration And Reaction Rate
1,776 wordster> How concentration affects reaction rate. The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the solution will become yellow and will change from being transparent to translucent to opaque. The sulphur is formed as a solid but not in the usual precipitation way. Na 2 + S 2 + 2 HCL 2 NaCl+...

Light And Dark Black And White
1,313 wordsPerception involves the input of basic information from a retinal image. Retinal images can be ambiguous in terms of size and orientation of lines, blood vessels infront of the retina, eye tremors and the blind spot can affect perceptual responses. One retinal pattern can lead to different interpretations and distorted images from inadequate sensory data, but perception of something as a recognisable object remains stable despite variations in the retinal image, such as light, or position of the...

Digital Image Light Intensity
1,152 wordsCat Scans Images can be processed by optical, photographic, and electronic means, but image processing using digital computers is the most common method because digital methods are fast, flexible, and precise. In the future, Electro-optical and some analog image-processing methods may be commonly used. This article focuses on the use of digital computer methods. In a typical digital image processing system, the source of the image is usually visible light reflected from or transmitted through va...

1,614 wordsEffect Of Photosyntheses And Respiration On The Effect Of Photosyntheses And Respiration On The Environment Introduction: The environment can be defined as the surroundings in which as organism lives, including the climate, the physical and chemical conditions of its habitat and its relationship with other living things. Given the above understanding, it is therefore important that the right environment factors are in existence for some chemical reactions to take place. In the absence of optimum...

H 2 O Carbon Dioxide
854 wordsColours Chloroplasts contain several different pigments the majority of which are chlorophyll a and chlorophyll b. Both of these types of chlorophyll absorb similar wavelengths of light, but chlorophyll a absorbs a slightly higher wavelength than chlorophyll b. Neither chlorophyll absorbs much light in the green region of the spectrum thus making it appear green. This can be plotted onto a graph (fig 1. 1). This graph is called the Absorption Spectrum. The Absorption Spectrum is very similar in ...

Rate Of Reaction Amount Of Water
1,531 wordsPhotosynthesis is a very important process in nature. It is the production of energy in the form of glucose involving water from the soil, carbon dioxide from the air and light energy. It takes place in all green plants, which use the green chlorophyll, held in chloroplasts in the leaves, to trap light. The main site of photosynthesis is the palisade mesophyll cells in the leaf of a plant. It is these cells that contain the green chloroplasts and are very well adapted to their task. They are nea...
