THE PERIODIC TABLE HISTORICAL BACKGROUND The idea that all things are elements or combinations of elements can be found in the writings of the ancient Greeks and other early peoples. Although this idea may seem simple‚ it is very difficult to decide if a substance is indeed an element or a compound. There were twelve chemical elements discovered in ancient times‚ but it was not known that they were elements. Another 76 elements were discovered between 1557 and 1925. Many mistakes were made in

Osmosis Lab: Potatoes and Elodea Background Information: Cells have a need to regulate their internal environment. They need to be able to this because cells often find themselves in environments where the concentration of dissolved solids outside the cell is different from the number of dissolved solids inside the cell. Since the solids can not move across the membrane‚ the cell responds by moving water either into or out of the cell in an attempt to balance the number dissolved particles.

GCSE - Human Physiology and Health An experiment to investigate what affect sucrose solution has on potato tissue. Background Osmosis is the movement of water molecules‚ across a partially permeable membrane from a region of high concentration of water to a low concentration of water molecules. A partially permeable membrane is a membrane with holes in it small enough for only water to go through it. Big molecules like glucose cannot fit through it. Osmosis allows plants to take in water

It also created solutions containing varying levels of concentrations and densities. Equations were used to figure the molecular weight of the sugar‚ and the number of moles of sugar in the volumetric flask. There was also an equation to figure the Molarity‚ as well. As a result of the experiment‚ I now have a better understanding of the density of a concentration‚ and what Molarity is .

expectation is to succeed and find out who they really are and what they mean to the people around them. The Cats Table is a book written by Michael Ondaatje. It narrates the story of Michael Ondaatje‚ a fictional depiction of the author at the age of eleven. Michael or “Mynah” as he called‚ boards upon a passenger liner called the Oronsay from Colombo‚ Sri Lanka to London‚ England. His 3 month journey has a lifelong impact that sets the tone for his future. The author displays this story as memoir

flask using a volumetric pipette. The volumetric flask was then filled to the mark with distilled water. The flask was covered with Parafilm and inverted to mix. The next part of the experiment was to determine the Vitamin C in a solution of known concentration. Observations of the Vitamin C sample and the amount found on the label was recorded. A tared piece of weighing paper was used to weigh 0.27 g of Vitamin C. The Vitamin C was then transferred to a clean 50 mL volumetric flask. The flask was filled
