Determining the Limiting Reactant and Percent Yield in a Precipitation Reaction Objectives: Observe the reaction between solutions of sodium carbonate and calcium chloride. Determine which of the reactants is the limiting reactant and which is the excess reactant. Determine the theoretical mass of precipitate that should form. Compare the actual mass with the theoretical mass of precipitate and calculate the percent yield. Materials: Balance 0.70 M sodium carbonate solution‚ Na2CO3(aq)

Discuss the role of the supernatural in determining the fate of Macbeth and Lady Macbeth in Act 1. In the play “Macbeth” by William Shakespeare‚ the supernatural is given a significant role in influencing the lives of two of the main characters‚ Macbeth and Lady Macbeth. This can be seen all throughout Act 1 where the supernatural is presented in forms of witches‚ spells‚ prophecies and spirits. The supernatural indirectly determines the fate of Macbeth and Lady Macbeth and does give apparent

Abstract In this experiment‚ the Ksp for calcium sulfate dihydrate‚ CaSO4·2H2O‚ by titrating 4 times a calcium sulfate dihydrate solution with diprotic EDTA‚ H2(EDTA)2-. For each trial we found the Ksp by means of molarities and activities. The results for the Ksp using only molarities was very different than the Ksp using activities. The average Ksp using molarity only was 2.26 x 10-4 and the average Ksp using activity turned out to be 2.31 x 10-5. The actual Ksp however‚ is 3.14 x 10-5. A percent

Determining the Ksp of Calcium Hydroxide by Titration of Saturated Ca(OH)2(aq) with HCl(aq) Abstract: Titration is a technique that has been used in this experiment to identify the Ksp value of calcium hydroxide in order to determine the extent to which the compound is soluble in water. A known volume of 50 mL of hydrochloric acid‚ a concentration of 0.05 M hydrochloric acid‚ a volume of 50 mL calcium hydroxide base‚ an unknown concentration

Socialisation refers to the process of learning one’s culture and how to live within it. The process of socialisation involves the transmission of culture from one generation to the next. It is during socialisation that individuals learn the values and norms that play such an important part in shaping human behaviour. Socialisation provides the skills and habits necessary for acting and participating within one’s society. Charles Cooley divided socialisation into two stages – primary and secondary

Objective 1. Use the analytical balance to weigh a given hydrated salt as accurate as possible in order to determine the weight of water in the salt Introduction Balances are important laboratory equipment as they are used to determine the mass of materials. Today‚ most balances used in the laboratory are analytical balances which can give readings up to four decimal places or higher. High accuracy is needed in certain experimental work such as material analysis or those involving small change

The internationalization of human resource management has increased the scope of traditional HRM. Today‚ HR practitioners not only manage people from their home country‚ but one that involve managing many diverse nationalities‚ with which the culture of staff and employees are already well-known or predicted. Companies start business within their country of origin and staff are hired from within that country. However‚ with the arrival of globalization and the shift from industrial to information

Method 1- Titration • For the titration‚ it is necessary to dilute the Sodium Hydroxide so that it is an easier concentration to titrate. Using a 25cm3 pipette‚ washed out with some of the NaOH solution‚ transfer 25cm3 of the solution to a 250 cm3 volumetric flask‚ and fill to the line with distilled water. The alkali will now have a concentration of 0.1 mol dm-3. • In the titration‚ the NaOH will be in the burette‚ and will be titrated into HCl in a conical flask: NaOH (aq) + HCl (aq) NaCl
