when oxygen and a hydrocarbon react to create water and carbon dioxide. In this experiment‚ we were meant understand and explain what a reaction were to look like in real life and see patterns in reactions. We did reactions between Copper metal‚ Magnesium metal in fire for a synthesis reaction. Silver nitrate and Copper metal and Zinc metal and Hydrochloric acid for a single replacement reaction. Nitric acid and sodium hydroxide‚ nitric acid and sodium carbonate‚ and

Which Antacid Works the Best? Heartburn is a condition characterized by a burning feeling in the chest and a sour or bitter taste in the mouth. Heartburn usually develops when the acidic contents of the stomach flow back‚ or regurgitate‚ into the esophagus‚ the muscular tube that carries food from the throat to the stomach. Approximately one in ten adults experience heartburn once a week. Heartburn is more common in pregnant women because of the pressure the expanding uterus exerts on the stomach

reactions will be analyzed to classify the chemical reactions into different groups. Hypothesis Reaction 1- My hypothesis for reaction 1 is that the magnesium ribbon will crumble. The explanation i have for this is that i when you put a object long enough on a fire it will probably crumble. Reaction 2- My hypothesis for reaction 2 is that the magnesium metal ribbon will make. The test tube will become hot. When a burning wood split is placed in the mouth of the tube‚ the flame goes out and the remains

volume is directly correlated by the how much gas is in the eudiometer‚ the more gas in the eudiometer‚ the bigger the volume and R value. If some of the magnesium ribbon was left over after the reaction‚ then the value of R would increase. This is because having extra magnesium leftover means that it came in excess and there was more magnesium to react

Get Charged Up Lab Report Abstract Get Charged Up Magnesium ribbon was reacted with Hydrochloric acid in three different experiments to determine the charge on a metal ion. After running multiple tests in the three different procedures‚ the Crystallization method proved to be the best method for determining the charge of the metal ion by using mole to mole ratio. Introduction The objective of the Get Charged Up lab was to determine the charge on a metal ion reacting with HCl by determine
