The Law of Definite Proportions states that a chemical compound contains the same element in exactly the same proportions by mass regardless of the size of the sample or source of the compound. This relates to the magnesium oxide lab because we tested out this theory to see if it is true that the law of definite proportions says that a chemical compound contains the same element in exactly the same proportions by mass regardless of the size of the sample or source of the compound. In this experiment

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

Magnesium (Mg) has an atomic number of 12 and an atomic mass of 24. It has 12 protons‚ 12 neutrons (varies with isotopes)‚ and 12 electrons (if it has no charge). Magnesium has a boiling point of 1363 K (1091 C/1944 F) and a melting point of 923 K (650 C/1202 F). At room temperature magnesium is solid. You can buy magnesium for $0.83 per lb. Magnesium is a metal and belongs to the alkaline-earth metal family. Magnesium was named after the city of Magnesia; it was discovered by Bussy in 1828 A.D.

America demonstrated its power to the Soviets and the world by the extraordinary triumph of the first moon landing in 1969. In order to fully appreciate the significance of the lunar landing of Apollo 11‚ one must review the history of the early U. S. space program‚ from its inception to the successful completion of the Apollo mission. The United States and the Soviets began their fierce competition after World War II‚ the Cold War era; not only was the arms race on the ground‚ but also race

Whilst reacting with the hydrochloric acid‚ it dissolved and bubbles were visible. The hydrochloric acid slowly diffused downwards. Calculations: Volume of un-diffused hydrochloric acid = 25 cm³ Average mass of magnesium = 0.038

Finding the formula of magnesium oxide Aims When magnesium is heated in air‚ it reacts with oxygen. During this oxidation reaction‚ magnesium oxide is produced. This increases the mass. If we know the mass of magnesium at the start‚ and the mass of magnesium oxide produced at the end‚ we can work out the mass of oxygen which has been combined with the magnesium. We can use these masses to work out the formula of magnesium oxide. Eye protection must be worn Apparatus Crucible and lid

Tittle: protection *click* Intro: Some people say that the government should be more responsible for damage done to the environment by harmful corporations. A reason behind this maybe is that the government holds all the supremacy. Other people disagree and say that the government should not be responsible for protecting environments for damaging corporations. Other people may say this since the government has many other problems that are at a higher priority. The government should be more responsible
