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

than they use‚ however it is just not thrown away‚ it is stored in the form of starch and other carbs which is then reserved for extra energy or building materials. The metabolic processes of cellular respiration and photosynthesis recycle oxygen‚ as it is a reactant in respiration and a product in photosynthesis. Oxygen is used as the last receptor in the Electron Transport Chain‚ when the hydrogen ions from the NADH bind to the oxygen forming water (Freeman‚ 2002). The water enters

Keeping conditions inside the body the same is called homeostasis. It’s not easy. Lots of things have to happen‚ e.g. energy transferred between body and environment‚ carbon dioxide is a waste product of respiration and has to be transported by the bloodstream to the lungs where it is breathed out‚ waste and waste products are filtered out of the blood and excreted in the urine. An incubator has a temperature sensor‚ a thermostat with a switch and a heater. Negative feedback happens when one factor

Experiment IV: Study of Krebs cycle using Mitochondria from Mung Bean Seedlings INTRODUCTION The mitochondria is a very important organelle in the plant cell because it carries out very important cellular reactions in the cell like the Krebs cycle and oxidative phosphorylation which is how the plants produce ATP from the pyruvate produced through glycolysis (Meyer and Millar‚ 2008). Glycolysis produces a net of 2 ATP for the plant which is not enough for the cell to function while the Krebs cycle

Abstract Photosynthesis is a food making process for algae and plants. The photosynthesis process rate varies from different wavelengths and intensities of light. This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. The mixtures of DCPIP with water‚ PO4 buffer‚ and chloroplast will be prepared in a number of cuvettes. The cuvettes were tested individually at different wavelengths and intensities to find the optimal rate

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
