Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

The Purpose of lab 1.4 Measuring Volume by Displacement of Water was to determine the fraction of air in different granulated solids. The lab cocised of one test done on four different granular solid; with up to 3 trials on each solid. When all tests are done and put in tables‚ and the calculations are made‚ the conclusion is that grain size does not affect that fraction of air. To be able to find the fraction of air‚ 3 measurement had to be taken‚ the volume of the solid with air‚ the volume of

Uncertainty avoidance: The dimension Uncertainty Avoidance has to do with the way that a society deals with the fact that the future can never be known: should we try to control the future or just let it happen? This ambiguity brings with it anxiety and different cultures have learnt to deal with this anxiety in different ways. At 30 China has a low score on uncertainty avoidance. None the less‚ adherence to laws and rules may be flexible to suit the actual situation and pragmatism is a fact of

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

density of water is 999.97 kg/m³ . Variables: Manipulated Variable Method of controlling Volume of water The volume of the water is measured by dropping water into the cylinder. Random error such as parallax error would occur. So I took the measurement three times. 0.00001m³ of water is added to the cylinder each time. . The experiment is conducted for volume of water of 0.00001m³‚ 0.00002m³‚ 0.00003m³‚ 0.00004m³‚ 0.00005m³‚ 0.00006m³‚ 0.00007m³‚ 0.00008m³‚ 0.00009m³ and 0.00010m³. Responding

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous
