it is. In the experiment conducted‚ the three metals‚ magnesium‚ zinc and copper each had to undergo displacement reactions and reactions with water‚ oxygen and dilute acids‚ to arrange them in the order of their reactivity. Generally‚ the more easily a metal burns in air to form an oxide‚ the higher up it is in the reactivity series. It was observed that both zinc and magnesium burned in air to form their corresponding metal oxides (magnesium oxide and zinc oxide) but copper did not undergo any

on the reaction of magnesium and salt water to produce hydrogen: Mg (s) + 2H2O (l) -> Mg2+ (aq) + H2 (g) ↑ + 2OH- (aq) s: solid; l: liquid; g: gaseous; aq: in solution; the vertical arrow indicates that gas is released. This reaction is very slow‚ due to passivation‚ so to speed it up‚ iron and salt are added. Passivation is the process by which a material is made less reactive‚ usually by the deposition of a layer of oxide on its surface: if you place a strip of magnesium into cold water‚ its

Statement of the problem. What are the other alternatives that we can do on that banana peels aside from making it as fertilizer? C. Scope and Delimitation Base on our knowledge‚ the magnesium and potassium that are on the table of elements‚ gives vitamins on our tooth. We think that if potassium and magnesium gives vitamins on our tooth‚ it is possible that it can whiten our tooth D. Significance of the study The Benefits of the banana peel to whiten our teeth is to make some people save more

extremely reactive chemical compounds used in the synthesis of hydrocarbons‚ alcohols‚ carboxylic acids‚ and other compounds. A gringard reagent is an organic magnesium halide dissolved in a nonreactive solvent (like diethyl ether). The substance is made up of an organic group joined by a high polar covalent bond to magnesium‚ while magnesium is joined by an ionic bond to a halogen (like bromide) a gringard reagent will react with water‚ oxygen or almost any other electrophilic organic compound to

Water is to be considered “hard” if it contains unusually high levels of dissolved magnesium‚ and calcium ions. This can be an issue for some people because hard water reacts with soap and it forms an insoluble salt or curds‚ which then in turn may leave your clothing looking yellow. Hard water can be softened by filtering your water through a household water softener to remove some of the excess magnesium

Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific time interval. Overview of the experiment: In this reaction two substances will be present in the solution‚ magnesium and hydrochloric acid. During the reaction magnesium particles will collide with the

Coralde Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines Results and Discussion A combustion reaction is a reaction that liberates heat and light. Magnesium is a stable element and reacts violently with evolution of much heat and light. The reason the magnesium burned in carbon dioxide was because it combined with the oxygen in the CO2 leaving elemental carbon behind.
