    variable will affect the amount of Gas produced from a Calcium Carbonate and Hydrochloric Acid Reaction. The Science Calcium Carbonate is a generally white or colourless mineral that is translucent. When compressed or exposed to great heat the mineral binds together in small to large clumps forming calcium Carbonate Chips, however left in it's formed state it is powder, a chalk like substance. I could use either forms of the Calcium Carbonate for the experiment. Hydrochloric Acid, is a clear, colourless

    While the egg is in the vinegar, the vinegar eats away the shell and toughens the membrane so that it can “bounce”. The acetic acid in the vinegar breaks apart the solid calcium carbonate that’s in the shell of the egg. The calcium ions float free (calcium ions are atoms that are missing electrons), while the carbonate goes to make carbon dioxide—the bubbles that you see. (http://www.exploratorium.edu/cooking/eggs/activity-naked.html ) If you go the hardboiled route with the eggs there’s not much

    Factors Affecting the Decomposition of Marble Buildings by Acid Rain Background Acid Rain: Nitrogen acids and sulphur dioxides come out of tall chimneys and vehicles. These go into the air, and air currents carry the gases away, and they react with water vapour and oxygen. This produces H2SO4 (sulphuric acid) and HNO3 (nitric acid). The acids become part of a cloud, and it falls down to earth, as acid rain or snow. This can end up miles away from the original source. The acid rain removes nutrients

    Investigation of the reaction between hydrochloric acid and marble chips A chemical reaction is when two or more substance called reactants are chemically bonded to form a new product, as a result of the process, for a reaction to take place, the particles must have enough kinetic energy to collide and form new bonds , this is called a successful collision. The minimum amount of energy needed for a successful collision is activation energy, which is “The energy that an atomic system must acquire

    Alka Seltzer Dissolving at Different Temperatures The variable that I will change will be the temperature of the water that the Alka Seltzer is put in. For my results I will measure the time taken for the Alka seltzer tablet to completely dissolve in water at different temperatures. Input variables: * Varying surface area of Alka-Seltzer tablet, i.e. if cut into smaller pieces or crushed it will increase the surface area. (If the surface area is increased (more powdered) the rate

    in a compound mixture of calcium carbonate; used as a building material (limestone). You must include why and how the metal is extracted. Calcium is extracted through electrolysis (2CaO ----- > 2Ca + O2). This produces 98.6% purity, which can further be extracted to 99.5% through subliming. Once it is extracted it forms into a n... ... middle of paper ... ...cium carbonate. Calcium chloride is also a byproduct in the Solway process used to make sodium carbonate.

    be difficult, producing scale on pots. Some vegetables cooked in hard water lose colour and flavour. Beans and peas become tough and shrivelled. Hard water may also shorten the life of plumbing and water heaters. When water containing calcium carbonate is heated, a hard scale is formed that can plug pipes and coat heating elements. Scale is also a poor heat conductor. With increased deposits on the unit, heat is not transmitted to the water fast enough and overheating of the metal causes failure
