    Different elements give off different colors when heated because they all have different chemical properties‚ therefore‚ they will react differently under high temperatures. For example‚ [1] strontium‚ lithium carbonate‚ and strontium carbonate are often used in fireworks to create a red color. Calcium may be used to create orange‚ sodium for yellow‚ aluminum for white‚ barium chloride for green‚ copper for blue‚ strontium and copper for purple‚ and titanium for silver. Even though all elements give off

    predominantly calcium and magnesium‚ and is measured as the equivalent concentration of calcium carbonate (in milligrams per litre). Water hardness is usually noticed because of difficulty in lathering soap and the formation of a scum in the bathtub. Ca2+ and Mg2+ form insoluble salts with soaps causing precipitation of the soap scum. Another effect of hard water is “boiler scale”. When hard water comes into contact with dissolved carbonates‚ a precipitate of insoluble calcium carbonate forms. This

    “element”) and metron (meaning “measure”). Stoichiometry is an important field of chemistry that uses calculations to determine the quantities (masses‚ volumes) of reactants and products involved in chemical reactions. It is a very mathematical part of chemistry. In this experiment‚ you will react a known amount of sodium carbonate solution with a known amount of calcium chloride solution. The skeletal (unbalanced) equation for the resulting double replacement reaction is: Na2CO3(aq)

    the Calcium Carbonate out of the beaker and into the filter during step 5‚ would your percent yield be larger or smaller? If you do not wash all of the Calcium Carbonate out‚ then the percent yield would be smaller because there is enough calcium carbonate left in the beaker that would have attributed to the final yield. b. If you used tap water instead of DI water what do you think would happen? Why? If you used tap water‚ the coffee filter would have weighed more after the calcium carbonate went
