Title : Osmosis in Quail’s Eggs Research Question What is the effect of different concentrations of sodium Chloride (NaCl) on the mass of the de-shelled quail’s eggs? Introduction Osmosis is an example of passive transport. Osmosis is defined as the movement of water molecules‚ down its concentration gradient‚ from an area of high water concentration (low solute concentration) to an area of lower water concentration (high solute concentration) through a selectively permeable membrane. Osmosis

An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed‚ resulting in a change in the molecular composition of substances. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: ¡¤ changing the surface area of any solids involved ¡¤ changing the concentration of reactants in solution ¡¤ changing the temperature

SOCIAL RESPONSIBILITY SHELL IN NIGERIA The entry of Shell D’Arcy Exploration Company into the search for oil across the entire Nigerian colony in 1937 marked a watershed in the history of oil and gas resources in the Niger Delta region. The Anglo-Saxon Petroleum‚ according to Steyn (2009)1‚ was renamed by that of the Shell Overseas Exploration Company in the official license in 1937. The exploration eventually resulted in a large commercial oil discovery. Shell Nigeria is the common name

investigation: The speed of a metal carbonate breaking down depends on where the metal is in the reactivity series. The more reactive a metal is the slower it takes for it to breakdown. The less reactive a metal is it breaks down faster. Explain the hypothesis using scientific ideas: The metal carbonate which is lower in the reactivity series such as copper can thermally decompose much faster because it is the least reactive metal so its an unstable carbonate and the bonds are much weaker. So

Give a conclusion‚ which describes why the mass of copper carbonate may have changed during your experiment. When the copper carbonate is heated it decomposes forming copper oxide and carbon dioxide. The copper carbonate turns into a bright

Eggs are laid by female animals of many different species‚ including birds‚ reptiles‚ amphibians‚ and fish‚ and have been eaten by humans for thousands of years.[1] Bird and reptile eggs consist of a protective eggshell‚ albumen (egg white)‚ and vitellus (egg yolk)‚ contained within various thin membranes. Popular choices for egg consumption are chicken‚ duck‚ quail‚ roe‚ and caviar‚ but the egg most often consumed by humans is the chicken egg. Bird eggs have been valuable foodstuffs since prehistory

Investigating the rate of reaction between Marble Chips (Calcium Carbonate) and hydrochloric acid Aim. In the investigation I am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small/large pieces of Marble Chips (Calcium Carbonate) and Hydrochloric acid per minute. Hypothesis. The rate of reaction increases when the surface area of a solid reactant is increased. This happens because by

the other hand Mollusk Shells specifically Mussel Shells and Oyster Shells are commonly consumed as food or used in pearl production. But once the meat of the shell is eaten or the pearl is removed‚ these shells become a non-usable waste products that adds up to our rapidly increasing pile of garbage‚ that is becoming a very huge problem for us. Nowadays‚ even landfills where we throw our garbage is becoming very crowded and too occupied with all of our garbage. These shells serves no useful purpose
