Determination Of The Valency Of Magnesium

A known starting mass of magnesium and the measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium Introduction Stoichiometry is the study of the quantitative relationship between amounts of reactants and products of a reaction. Stoichiometry can be used to calculate the amount of a product formed when given the reactants and a percentage yield. In the case of this experiment, a known starting mass of magnesium ribbon and the amount of...

Magnesium Oxide

Aim: to perform a firsthand investigation to compare the physical and chemical properties of magnesium and oxygen when they are experimented to form magnesium oxide Theory: The empirical formula of a compound is the formula that tells us the ratio in which the atoms are present in the compound. To calculate an empirical formula: - Write down the masses of all of the elements present - Convert masses to moles (by dividing by atomic weights in grams) - Divide through by the smallest number of...

oxidation-reduction reaction of magnesium and hydrochloric acid solution. We compared the experimental measured amount of a product and the amount predicted by the theoretical calculation of a balanced equation: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g) PROCEDURE First we obtained a strip of pre-cut magnesium ribbon, cleaned it with steel wool to remove any signs of oxidation from the strip (which would alter our results), and then weighed it (individual masses of the magnesium strips for each trial can...

Room Temperature Magnesium

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....

Antacids: Calcium Carbonate and Magnesium Compounds

high presence of aluminum and magnesium hydroxides in non-absorbable antacids can be effectively used to prevent significant stress ulcer bleeding in post-operative patients or those with severe burns. MECHANISM OF ACTION OF ANTACIDS Antacids were developed based on the hydroxides and carbonates of the group II and III metals, as well as the bicarbonates of the alkali metals. All antacids contain at least one of the following metals: aluminum, calcium, magnesium, sodium, potassium, or bismuth...

Rate of reaction between Hydrochloric acid and magnesium

Aim: The aim of my experiment is to find out the rate of reaction between Hydrochloric acid (HCL) and Magnesium (Mg) in different temperatures. The products that will be formed are Magnesium Chloride (MgCl2) and Hydrogen (H2). Prediction: I predict that as the temperature increases the rate of reaction also increases. To further explore the fact I further predict that the rate of reaction will double for every 10° C rise in temperature. I further predict as the temperature rises by 10° C the rate...
