Its all really good, just make the hypothesis sound more professional, you don't need to mention it is a guess because that is what a hypothesis is. Also in the Discussion include some information on Accuracy, Reliability and Validity and Some possible solutions to the problems encountered.

Sulfur Dioxide: 1. When organic matter decomposes it produces hydrogen sulfide (H<SUB>2</SUB>S), which then oxidises (reacts with oxygen) to produce sulfur dioxide: 2H<SUB>2</SUB>S<SUB> (g)</SUB> + 3O<SUB>2 (g) --> </SUB>2SO<SUB>2 (g)</SUB> + 2H<SUB>2</SUB>O...

So when we refer to our Table of Standard Reduction Potentials we can see that Ni has a reduction potential of -0.24 V, whereas Cl2 (g) is +1.36V. Therefore Ni will undergo oxidation and Cl2 (g) will be reduced. So we can deduce that more Ni atoms will go into ionic state after displacing Cl2...

This can be sort of confusing, especially the relationship between the ciliary muscles, the suspensory ligaments and the shape of the lens. Try to make sense of the following: If the lens becomes more rounded (greater curvature) it refracts light to a greater extent and close objects can be...

– Estimated diameter of small (400x) field of view: 0.45mm – Estimated number of red blood cells (400x): 53 – Estimated size (diameter) of a red blood cell: 0.45mm/53 = 8.5 x 10-3 mm x 1000 = 8.5 micrometers This is just an example of results. Your results may vary...

– DEFINITION: Enantiostasis is the maintenance of metabolic and physiological functions, in the absence of homeostasis, in an organism in response to variations in the environment. – An estuary is where a river meets the sea, and freshwater mixes with saltwater – In such an...

Like sinophile said, you want to cut longitudinally, meaning cut down the long side. So if you place the kidney on a horizontal table, cut horizontally at the level of entry of the ureter on the opposite long side. Cut all the way through so you get a neat cross section of the inside.

– Diffusion and osmosis are both examples of passive transport, relying on random movements of molecules. – Diffusion is too slow for the normal functioning of the body and does not select for reabsorption of useful solutes. – Osmosis only deals with the movement of water...

– Computer chips: With superconductors no heat is produced and so wires and transistors on a computer chip could be packed much more closely together and with no heat produced, making computing power much more faster. – Generators and motors: The use of superconductors in...

What whitnall8 said is spot on, using the arrow method is the best way to remember it, so always try to visualize a traditonal arrow. So if you fire an arrow horizontally away from yourself, you will see the feathers. If someone fires an arrow straight at your, you will see the sharp point.

The metre was first defined in 1793 as one ten-millionth of the length of the Earth's quadrant passing through Paris. When SI of units was set up (1875), metre was defined as the distance between two lines inscribed on a single bar of platinum-iridium alloy. Current definition is much more...

The ‘sling-shot effect’ allows satellites to change speed and direction and gain some angular momentum and kinetic energy of the planet. Gravity allows the ‘coupling’ between the probe and planet via an “elastic collision” to facilitate the transfer. So essentially, The Law of...

Biopia and Pwnage101 gave excellent information. Just one more little thing - be aware that in the length contraction, time dilation and mass dilation formulas, Lv, tv and mv (with subscript v's) are for the moving frame of reference whereas L0, t0 and m0 (with subscrip 0's) are the rest frame...

What icecoffee stated is spot on, so apart from The factors we can ascertain from Newton's Law - distance and mass, the other main factors affecting strength of gravitational force are Altitude, Earth being flatter at the poles, Centripetal force and Varying density of the Earth.

The main points you need to know are as follows: – Aim: To measure the existence of an aether wind which caused the speed of light to vary. – Equipment: Interferometer mounted on a large stone block floating on mercury so it could be rotated to repeat the experiment in different...
