chemical equation. Example: In this equation‚ A and B are called reactants and C and D are called the products. Arrow shows the direction of chemical reaction. Condition‚ if any‚ is written generally above the arrow. When hydrogen reacts with oxygen‚ it gives water. This reaction can be represented by following chemical equation. In first equation words are used and in second symbols of substances are used to write the chemical equation. For convenience‚ symbol of substance is used to represent

blood cells) are biconcave disks‚ containing haemoglobin that transports oxygen. They transport the oxygen to cells all over the body. The surface area to volume ratio is very large on the erythrocytes so oxygen can diffuse very quickly into the cell. They lack organelles meaning that there is more room for haemoglobin. They are small and have a flexible membrane which allows them to fit through tiny capillaries and transport oxygen extremely close to cells. Leucocytes (also called white blood cells)

blood into and out of the lungs (Porth‚ 2011)‚ this leaves Margaret at risk of developing respiratory failure (National Institute of Health‚ 2011). The oedema in Margaret’s alveoli is restricting the flow of oxygen in the blood (Porth‚ 2011). Margaret is having trouble with the exchange of oxygen and carbon dioxide‚ a rise in carbon dioxide in the blood sends signals to the brain to increase breathing and to breathe deeper (Starr‚ Evers & Starr‚ 2010). Margaret is lying on her left side and is

respiratory system is to supply the body with oxygen and to dispose of carbon dioxide. To do this‚ at least four distinct events‚ collectively called respiration‚ must occur: 1. Pulmonary ventilation Air must move into and out of the lungs so that the gases in the air sacs (alveoli) of the lungs are continuously changed and refreshed. This is commonly called breathing. 2. External respiration Gas exchange (oxygen loading and carbon dioxide unloading)

By Derrick Deacon - There are 92 naturally occurring elements‚ only 17 of them make up 99.5% of the earth’s crust (including oceans and atmosphere). - In living things (plants‚ animals‚ people) the six most abundant elements are carbon‚ hydrogen‚ oxygen‚ nitrogen‚ phosphorus and sulfur. - The universe is dominated by the elements hydrogen (83%) and helium (16%) 1. The Crust The outside of the earth is a thin crust which is approximately 20 to 40km thick. The crust is a formation of dips and

have a shorter chain length‚ which makes it pack not as close as straight alkane. For ether‚ it has one oxygen; there are polar bonds. However‚ since the functional group is R-O-R’‚for oxygen the VSEPER shape is linear so that the polarity canceled out. The compound is still non-polar‚ and there is only dispersion force. Ether has higher boiling point than alkane‚ alkene and alkyne because oxygen has higher electron negativity. Cis and Trans: cis usually have higher boiling point because the side chain

In our bodies we need energy so that we could do things that are possible such as; move our muscles‚ talk and all the other things that we do. Without energy all people would be useless not being able to do anything. Energy is needed to extract the oxygen from the areas in our bodies and diffuse it into our bloodstream. As warm blooded people we can only digest food and function if our bodies are at a certain temperature and have enough energy‚ and energy is required for this. We need energy to be

OBJECTIVE: The experiment was carried out to investigate the effects of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills‚ the experiment was done in order to determine how the rate of reaction will be altered‚ whether it will increase‚ decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant‚ animal‚ and microbial cell. There are thousands of different

Lab 1: Synthesis of Aspirin Introduction: The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. In this case‚ an acetyl group was added to salicylic acid‚ a naturally occurring compound with significant pharmaceutical value. Without the addition of the acetyl group‚ salicylic acid is an irritant to the gastro-intestinal (GI) tract. Once the acetyl group is added via a simple reaction‚ acetylsalicylic

up to twenty percent of oxygen this way‚ but specific species of turtles such as‚ the Australian Fitzroy River turtle and the American Eastern Painted turtle‚ can breathe up to seventy percent this way. The way this works is that turtles have one opening through which they excrete‚ urinate‚ and lay eggs called the cloaca. On the sides of the cloaca there are two sacs called bursa that are tissues. The bursas contain blood vessels through which oxygen is diffused. The oxygen is then absorbed by the
