    types of sparks. In flame compositions‚ such as the stars that shoot out of rockets‚ potassium nitrate‚ salts of antimony‚ and sulfur maybe be used. For colored fire‚ potassium chlorate or potassium perchlorate is combined with a metal salt that determines the color. Inside each firework are small packets filled with chemicals‚ mainly metal salts and metal oxides‚ which react to produce an array of colors. When heated‚ the atoms of each element in the mix absorb energy causing its electrons to

    made mainly of calcium carbonate (CaCo3)
Some types of limestone are made of the remains of tiny animals and plants which lived in the sea millions of years ago
We dig limestone out of the ground in quarries
Its main use is as a building material/ in the manufacture of iron 
Powdered limestone + high temperature+ sand+ sodium carbonate= glass
powdered limestone + powdered clay + heat= cement
cement powder + water + sand +gravel= concrete
Limestone + strong heating= quicklime (calcium oxide) + carbon

    has a huge effect on calcium carbonate concentrations in ocean water. An increased concentration of CO₂ in the air then causes an increase in calcium carbonate levels in water. CO₂ is highly soluble in water‚ especially mineral water (“When Carbonate”). When carbon dioxide reacts with water it forms carbonic acid. CO₂ + H₂O ↔ H₂CO₃ This product can then go on to react and produce hydrogen ions and bicarbonate. H₂CO₃ ↔ H⁺ + HCO₃⁻ Bicarbonate is also a product of carbonate ions reacting with

    used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to decompose into two gases‚ due to the absence of anything solid or liquid following the reaction. A wood splint was used to determine that carbon dioxide was present‚ since the lit splint was extinguished when put in the test tube. Therefore‚ the other product is ammonium oxide. The fourth reaction occurred between calcium carbonate and hydrochloric

    | | | 10/3/2012 | | Aim: To determine the different types of hardness and alkalinity found in the water by titration methods. This is used to calculate the concentrations of calcium and magnesium found in the water. Principles: The hardness of water is determined to provide a measure of the quality of water for household and industrial use. Hard water is not a health hazard. Drinking hard water contributes a small amount of calcium and magnesium towards humans dietary needs.
