    Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen

    Chemical Reaction: Cold Packs CHM110 Chemical Reaction: Cold Packs Introduction Chemical reactions happen every day in a variety of ways. We will explore the science behind cold packs and the chemical reactions that happen at the molecular level. Furthermore‚ we will examine and explain what chemical bonds are formed‚ broken‚ or both. The product is a simple construct of two bags: one containing water (solvent) and the other a chemical compound called ammonium nitrate (NH4NO3). In order to activate

    Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance

    are called ‘Friedel-Crafts’ alkylations and acylations‚ named for Charles Friedel of France and James Crafts of the United States‚ who together developed the procedures in 1877. The Friedel-Crafts reactions are an important part of a synthetic chemist’s toolbox to this day. Friedel Crafts reactions‚ like their biochemical counterparts‚ require reactive electrophiles with significant carbocation character. One of the most common ways to alkylate an aromatic ring is to use an alkyl chloride electrophile

    chemical reaction takes place. For the purpose of this lab we measured the rate a balanced oxidation/reduction reaction between iodine‚ hydrogen‚ and bromate ion occurs. The above reaction occurs slowly so we used a coupled iodine clock reaction to measure the rate of the oxidation/reduction reaction because it occurs much faster but is still dependent upon the other reaction. To accomplish this‚ two mixtures were prepared in separate Erlenmeyer flasks. In the 250 ml flask .010M potassium iodide‚ .0010M

    Replacement Reactions (Data and Calculations) Objective: Classify the chemical reaction through observation‚ which each reagent produce when mixed with another reagent. After careful observation‚ be able to prove each observation using the net ionic equation. Background: First‚ a double-replacement reaction is when two cations in different compound switch anions‚ AX + BZ → BY. If either compounds are insoluble a precipitate occurs‚ and if there is no precipitate formed there is no reaction. Also‚

    Endothermic and Exothermic reactions A chemical reaction is a process in which one or more substances are chemically changed into one or more new substances. A chemical reaction may involve the motion of electrons in the forming and breaking of chemical bonds. Therefore when a chemical reaction takes place‚ energy is transferred to‚ or from‚ the environment. A Chemical reaction can either be exothermic or endothermic. Exothermic Reactions During an Exothermic Reaction a transfer of energy to the
