Origins of Magnesium - ORIGINS OF MAGNESIUM Magnesium is found in large amounts throughout our bodies. We obtain it predominantly from dietary sources. We can also obtain magnesium in many other places since it is the seventh most prevalent element from our universe. The earth’s crust contains large amounts of this element and we can obtain it from the minerals dolomite and carnallite. It is, however, most commonly extracted from our ocean waters. “Every cubic kilometer of seawater contains about 1.3 billion kilograms of magnesium”1 (Education)....   [tags: dietary, crust, water, salt, requirements] 1113 words

An Experiment to Determine the Total Hardness of 4 Different Types of Bottled Water - ... From the manufacturers’ claims, it is calculated that the average total hardness of bottled water is 29.25mg/L, in comparison to the total hardness of tap water which is 41.1mg/L, which still makes tap water harder than bottled water. In result, this meant that the hypothesis ‘bottled water will be harder than tap water as it comes from naturally occurring springs’ is incorrect as the results from the experiment prove that tap water is harder than bottled water. However, the hypothesis may still have a chance to be correct as there were many sources of error that was present in the investigation....   [tags: thank you water, evian water, tap water] 889 words

Does Concentrated Acid or Diluted Acid React Faster? - Does Concentrated Acid or Diluted Acid React Faster. Plan I am going to carry out a reaction between Magnesium ribbon and Hydrochloric acid. The aim of this investigation is to work out which reacts faster, concentrated acid or diluted acid. I will judge if the reaction is fast or slow by observing the bubbles which occur during the reaction and also observe if the Magnesium has disappeared. Only the concentration of the acid will be changed - the Magnesium is a solid. Magnesium + Hydrochloric Acid Magnesium Chloride + Hydrogen Mg(s) + 2HCl(aq) MgCl(aq) + H2 (g) There are four main factors which may affect rate of reaction....   [tags: Science Experiments Reaction Rates Essays] 1441 words

How Concentration Affects The Speed Of A Chemical Reaction - How Concentration Affects The Speed Of A Chemical Reaction Aim --- To investigate the effect of concentration of acid, in the reaction between dilute hydrochloric acid and magnesium ribbon. Preliminary Research -------------------- The rate of a chemical reaction is the measure of how fast the reaction takes place. In a reaction particles must collide and overcome the fixed amount of energy for the reaction to take place. This energy is called the activation energy. The rate of reaction depends on four factors: « Temperature - An increase in temperature produces an increase in rate of reaction....   [tags: Papers] 1364 words

Which Type of Salt will Increase the Boiling Point of Water the Most? - The researcher conducting this experiment is trying to find out which salt- Epsom, table salt, and sea salt- will increase the boiling point of water the most. Sodium chloride is believed to increase the boiling point of water because when salt is suspended into the water, the sodium and chlorine ions leave the “salt crystals” and mix with the water molecules. (“Why does salt… raise boiling point of water?”, 2009). People discovered salt around 900 B.C.
