SOLANO MARIANNE KRISTELLE E. YARRA INTRODUCTION Photosynthesis sustains almost all of the living world directly or indirectly. It is the process of converting light energy to chemical energy of sugars and other organic compounds. The process depends on the interaction between two sets of reactions‚ namely the

Introduction For this experiment‚ we are going to determine the effect of temperature on solubility‚ to be done in a chemical by dissolving a solute in a definite amount of solution which is saturated. Specifically‚ the goal of this experiment is to prepare a saturated solution of Na2C2O4 in water at different temperatures‚ determine the effect of temperature in solubility‚ and to apply Le Chatelier’s Principle. We can do all this by simply titrating a certain amount of standard KMnO4‚ and measuring

This occurs because these forests are exposed to cold and warm air‚ which makes them encounter all four seasons. Temperatures in the deciduous are estimated to be up to 50°. They also have precipitation of 30 to 60 inches a year. One of the traits these trees have is thick bark that protects them from cold or really hot weather. Deciduous forests can be found everywhere

A microprocessor incorporates the functions of a computer’s central processing unit (CPU) on a single integrated circuit (IC)‚ or at most a few integrated circuits. It is a multipurpose‚ programmable device that accepts digital data as input‚ processes it according to instructions stored in its memory‚ and provides results as output. It is an example of sequential digital logic‚ as it has internal memory. Microprocessors operate on numbers and symbols represented in the binary numeral system. The

monosaccharide reducing sugar (Kolej Mara Banting – Students’ Handbook for Biology HL Year 1). It is the simplest form of carbohydrate. In this experiment‚ sulphuric acid‚ H2SO4 and potassium permanganate‚ KMnO4 is added into glucose with different concentration and the time taken for the purple pink colour of potassium permanganate solution to change to colourless is recorded. This is because glucose donates electrons to the permanganate ions‚ causing it to change colour (Kolej Mara Banting – Students’

Auschwitz Concentration Camp Imagine that you were a 14 year old Jewish girl riding with your family and hundreds of other Jews and Gypsies packed into one tiny railroad car. You stop at an unfamiliar place were a man is screaming at you to get out. You have to watch your step getting out of the railcar because there are already dead people on the floor who passed on the trip here. Once you are out you are separated from your family‚ woman on one side men on the other. Kids are franticly

Purpose Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries‚ even when the surrounding temperature varies and is of higher or lower temperature than what is normal. The purpose of thermoregulation is to balance thermal inputs and thermal losses in the body so as to maintain a relatively constant core temperature of approximately 36.7 degrees celsius. If this was unable to take place the body may not be able to functions properly and it could result

HOW FAST ARE CHEMICAL REACTIONS? THEORY The study of reaction rates‚ how fast or how slow a reaction takes place‚ is known as chemical kinetics. The rate of chemical reactions varies greatly. Some reactions‚ such as the explosion of an atom bomb are uncontrollable. Reactions like the decay of radioactive carbon (14C) are so slow that it takes centuries to see any noticeable change. Between the two extremes are reactions that can be measured in the laboratory. There are several factors that
