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

To whom it may concern‚ It has come to my attention that Liam‚ a young man of 23‚ had recently been diagnosed with severe liver damage. The disease had developed from 10 years of heavy drinking and as Liam was so young the disease was obviously more susceptible. After many advanced treatments being used on him‚ the only chance of saving Liam’s life was through a liver transplant‚ but sadly Liam was refused the transplant. Liam had begun drinking

Discussion: We have made four set-ups in two different specimens. Onion and Boat of Moses skin with water‚ 2%‚ 5% and 10% salt (NaCl) Solution. Based on our experiment‚ the result of the set up explains that the presence of the salt solution results in outward diffusion of water and the collapse of the protoplast. In table 1‚ we have observed under the microscope that the onionskin mounted with water has no results of plasmolyzed cell (0%). This time‚ we have repeated the procedure with 2% salt
