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) + CaCl2(aq) Æ NaCl(aq) + CaCO3(s) Note that three of the chemicals have

stoichiometry relationships‚ you will calculate a theoretical yield of CuO‚ and your actual yield. You then will calculate a percent yield. Copper(II) sulfate pentahydrate will be dissolved in water and reacted using a double replacement reaction with sodium hydroxide. The addition of hydroxide ions to a solution containing copper(II) ions results in the precipitation of copper(II) hydroxide. Subsequent heating of the copper(II) hydroxide results in decomposition to copper(II) oxide and water.

salt to see if it will harm the grass. First‚ thing is to get all the equipment needed to perform this experiment. I will need three round flower pots 1 inch in diameter and height. I will be using ¼ cup of ammonium sulphate fertilizer and ½ cup of sodium chloride concentrations salt‚ rock salt (halite)‚ and calcium magnesium acetate salt (Peeples‚ 1990). The last and final ingredient I will need is three different types of grass sod‚ St. Augustine grass‚ Bahia grass‚ and Buffalo grass cut in 5 inches

chemicals were collected in a beaker at the end of the practical and given to an adult to dispose of properly. Method: 1. Following the table‚ 10 drops of Copper Sulphate were placed in each test tube (five test tubes). 2. 10 drops of Sodium Chloride was added to the first test tube‚ 10 drops of Silver Nitrate to the second‚ and so on until each test tube contained Copper Sulphate and one other chemical. 3. Each reaction was recorded and written in the table. (see appendix one for
