ABSTRACT This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted in this experiment. The efficiency of antacid tablets was determined and compared when the number of grams of HCl can be neutralized by 1 gram of the tablet was found. First‚ the two antacid tablets (Kremil-S) were crushed and weighed

football from 1850 to today. The 1850’s saw drastic changes to most of Britain‚ the major change being the huge increase in urbanisation which was key to the development of association football. This was because the people of the urbanising areas ended up being in small spaces for the sheer number of people there was. This was only enhanced by the movement of rural-urban migration as people sought both work and a new life in the newly growing towns and cities. In the 1860’s -1880’s the Saturday

President Truman at the time was the president. The first

------------------------------------------------- By measuring the concentration of the hydroxide ion from a solution saturated with Ca(OH)2 titration analysis against HCl‚ the experiment’s objective is to determine the solubility constant of calcium hydroxide. But‚ there are few limitations in solubility constant concept‚ like the Diverse Ion effect and the Common ion effect. Sources of error probably were the assumptions made throughout the experiment and can be explained further by the limitations of the solubility constant

aggression (McLeod‚ 2011). Albert Bandura decided to conduct an experiment to test if other peoples’ actions influenced our emotions and thoughts. His experiment would be focused around aggression and included kids‚ adults and various toys. These kids would be from ages 3-5 year olds. Bandura would put kids in a room with an adult with a couple of toys; one being a giant inflatable doll better known as the Bobo doll. In his experiment‚ he had the child present in the room while the adult was hitting

Toyota has been operating and already proven that it’s possible to be a low cost producer of a differentiated product. It was able to achieve leadership in North America‚ surpassing General Motors. They continuously find ways to reduce production costs and at the same optimize its process so that it could introduce new models faster than its competitors. They’re known for their Toyota Production System (TPS) which other vehicular companies were trying to mimic. This TPS is the main reason why there’s

Parachute experiment Aim: The aim was to find the effect of holes on a parachute‚ varying their size and number. Hypothesis: 1. By increasing the number of holes‚ the time it will take to the parachute to reach the ground will be longer and its flight will be more balanced. 2. By increasing the size of the hole on the parachute‚ the time it will take to the parachute to reach the ground will be shorter and its flight will be less balanced.

Luminosity means how bright something is‚ and the luminosity of Gliese 581 is .2 percent of the Sun’s luminosity. From this information‚ we know that Gliese 581 is a very dim star! There are three confirmed and two other possible planets that orbit Gliese 581. Each of these five planets are close to the star and have a circular orbit. The planets orbiting Gliese 581 were named in the order they were discovered and are named Gliese e‚ Gliese b‚ Gliese c‚ Gliese g‚ and Gliese d. The mass of Gliese 581e is
