    In the first reaction‚ magnesium was burned to produce magnesium oxide. The reaction produced a bright light‚ which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to

    Covalent Bonding In a covalent bond‚ a pair of electrons is shared between two atoms. Each of the positively charged nuclei is attracted to the same negatively charged pair of electrons. The diagram: A and B are held together by this shared attraction. Covalent bonds are often drawn as dots and crosses diagrams to show that the electrons have come from two different atoms. Molecules have a certain fixed number of atoms in them joined together by covalent bonds. Examples: Bonding in hydrogen

    CALORIMETRY AND HESS’S LAW: FINDING ΔH FOR THE COMBUSTION OF MAGNESIUM MATERIALS: 12 oz. Styrofoam cup with lid‚ thermometer‚ 50-mL and 100-mL graduated cylinders‚ weighing boat‚ 1.0 M HCl‚ 1.0 M NaOH‚ magnesium ribbon‚ magnesium oxide‚ copper wire. PURPOSE: The purpose of this experiment is to determine the enthalpy change for the combustion of magnesium: Mg (s) + ½ O2 (g) → MgO (s) ΔHrxn = ΔH combustion by determining the ΔH values for reactions which can be combined together according

    Experiment on Metals Aim-To find out which of these metals will be most reactive with hydrochloric acid‚and plan an investigation to test it out.The Metals given:Calcium‚Aluminium‚Iron‚Magnesium and Zinc. Prediction-I predict that the metal will be the most reactive with hydrocholoric acid is calcium because calcium is in Group 2 which is the alkaline earth metals in the periodic table and because calcium is at the extreme left side of the periodic table and as you go across a period‚the element

The liquid in glass ionomer cement contains itaconic acid‚ tartaric acid‚ maleic acid and water. The powder includes zinc oxide‚ aluminum oxide and calcium. One of the best qualities about this type of cement is that it releases Fluoride‚ which helps prevent tooth decay. It slowly is released from this powder because of its special combination of glass‚ ceramic particles and a glassy

    Thermite Background: Thermite is a powder made from aluminum powder and a metal oxide [usually iron oxide (Fe2O3‚ known as rust)]. The thermite reaction is a redox reaction‚ where Aluminum reduces the oxide of another metal. For example‚ when using iron oxide (as I did) the equation would be Fe2O3(s) + 2 Al(s) -> Al2O3(s) + 2 Fe(l). Black or blue iron oxide (Fe3O4) could also be used. Other examples of possible oxides are manganese thermite (MnO2)‚ Cr2O3‚ and copper thermite (CuO). Aluminum can also

But for the Group IA and Group IIA elements and Group IVA elements‚ we didn’t use litmus paper. Then‚ we wrote a balanced equation to show the reaction between Metal Oxides and water. __________________________________________________________________________ INTRODUCTION Chemical periodicity is defined as the similarities of chemical
