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

The purpose of this lab was to find the empirical formula for magnesium oxide. To find this formula‚ a strip of Magnesium ribbon was burned in a crucible over a flame from a bunson burner. After the strip caught fire multiple times with the cover on‚ and 10 drops of distilled water were added‚ and the crucible was lightly heated. The crucible was then weighed and the mass recorded. Calculations were performed and the mole ratio of Mg to O was recorded. The results of other lab groups performing the

Mississippi Burning directed by Alan Parker is a film set in the mid 1960’s. It was set in the time of the Civil Rights Movement and throughout the film it is shown how badly coloured people were discriminated against during those times. The major theme in the film is racism and segregation between the white and the coloured people in Jessup County. The director has developed this theme by using different techniques such as having characters with different personalities and authority‚ by using various

composition by mass of magnesium oxide – Report Objective: To measure and calculate the ratio of magnesium to oxygen in magnesium oxide. To compare the lab ratio to the percent composition calculation based on the formula. Hypothesis: Based on the law of definite proportions‚ the percentage composition of magnesium oxide should be around 60% magnesium and 40% oxygen. Materials: * Goggles * Centigram or analytical balance * 2-4 cm magnesium ribbon * Steel
