Magnesium is one of the twenty-four elements on earth that are essential for life. It is vital in human metabolism; and if our magnesium levels are too high or too low‚ we could suffer from sleep disturbances. Magnesium is a very common element found on earth that is used for a lot of everyday items. Much of what we have today would not be possible without magnesium. Magnesium was originally discovered by Sir Humphry Davy in 1808‚ but some are not sure if he officially isolated the element. It was

Experiment 2: The Effect of Different Reactants on the Type of Gases Produced Abdul Aziz Malik Submission Date: 18th April 2012 Background Information In the experiment‚ when oxygen is being tested‚ a glowing splint will be used and when that splint is placed in to the mystery gas and the splint reignites‚ then the gas is oxygen. When hydrogen is being tested‚ a burning splint will be used and when the splint is placed in to the mystery gas and a “pop” sound occurs‚ then the gas is hydrogen

hypothesized correlation between ionic strength and degree of ionization of a weak acid‚ while determining the factors that would impact the degree of ionization using measurements of pH. It was initially required to prepare standard 20-mL solutions of varying concentration of acetic acid for use in the rest of the experiment. One solution of CH3COOH was supposedly developed to be 2.00M‚ however it is highly possible that the solutions of CH3COOH were not exactly the expected concentration‚ evident by the

factors of a chemical reaction affect the rate of reaction. This experiment focused on how temperature affects the rate of reaction for the reaction of alka-seltzer and water. The rate of a reaction is a value calculated to figure out how fast a chemical reaction occurs. There are three factors that can be changed that will affect the rate of a chemical reaction: surface area‚ concentration‚ and temperature. Temperature specifically affects the rate of a chemical reaction‚ because when the temperature

In the experiment‚ as the size of the cube decreased‚ the absorption rate increased‚ showing that the smaller cells absorbed more sodium hydroxide than bigger cells. The smaller cells were able to absorb more sodium hydroxide as they have a bigger surface area to volume ratio causing them to act more efficiently than the bigger cells. The smallest cell had a ratio of 1:12 while the biggest cell had a ratio of 1:2‚ leaving a gap of 5:12 causing the bigger cell to act less efficient in absorbing the

Hypothesis: As the caffeine concentration rises‚ so does the mean heart rate of daphnia. Risk Assessment: In this experiment there are the following risks both for the human that carries out the experiment and the daphnia: ← The human that carries out the experiment should be cautious not to touch the lamp with wet hands since it uses electricity. ← Also‚ be careful not to spill any of the pond water on the floor. ← As for the daphnia‚ there is a chance for them to die as when

When considering taking supplements‚ how often do we consider taking magnesium supplements? This mineral helps on the process of over 300 functions in our body‚ most important neurotransmitter and heart functions‚ and its consumption is essential for the regulation and development of these activities. The brain is one of the organs that benefit the most in taking magnesium supplements‚ magnesium activates ATP‚ a coenzyme that regulates your energy levels‚ making it a good complement to treat fatigue
