The five common methods that can be used to separate various types of mixtures are filtration‚ fractional distillation‚ evaporation‚ sublimation‚ and chromatography. Evaporation is the changing of a liquid into a gas often under the influence of heat. A mixture of a solid and liquid can be separated by evaporation. Filtration is a technique that uses a porous barrier to separate a solid from a liquid. A liquid

WHAT IS PHOTOSYNTHESIS? 3 Every day the total amount of energy that is captured through photosynthesis all across our planet is equal to approximately 135 terawatts. Now to put this number into perspective the entire human race consumes approximately 15 terawatts of energy daily. This means that there is 9 times more energy being absorbed every day through photosynthesis‚ as there is energy being consumed by all of mankind (Bridges 2008). In order to fully understand photosynthesis

The presence of light and of the green pigment chlorophyll makes the change of carbon dioxide and water to glucose and oxygen possible. It was Jan Ingenhouz with Jean Senebier in Geneva that founded the basic gist of the theory of photosynthesis in plants. My experiment involves testing different

Chemistry mixtures and solutions Background Information and Research 1. Paper chromatography is used to break down colors using water in order to see the way the colors separate. 2. Many doctors use it to test for alcohol in people’s blood. Marine biologists use it to check for pollutants in the water. Pharmacists use it to find out how much chemical is in a product‚ and what kinds. 3. All my references came from google. Purpose The purpose of this lab is to test what colors are in
